In the present investigation, three seed lots of eight varieties/genotypes, viz. DH 224, DH 226, DH 242, DH 259, DH 294, DH 296 (advance genotypes) and DH 228 (Hisar Bhoomit) and Hisar Anand (released varieties) of coriander were subjected to study the effect of natural ageing on different seed quality parameters. All the seed lots were analyzed for standard germination test (%), root length (cm), shoot length (cm), seedling dry weight (mg), seedling vigour index-I, seedling vigour index-II, accelerated ageing test (%), electrical conductivity (mS/cm/seed) of seed leachates, seed density (g/cc), dehydrogenase activity test (OD/g/mL), field emergence index and field establishment (%). Results revealed that all the varieties/genotypes showed the germination percentage above the Minimum Seed Certification Standards (60%) in Lot-A (½ year old seed) and Lot-B (1½ years old seed). Standard germination (%), seedling length (cm), seedling dry weight (mg), seedling vigour index-I &II, accelerated ageing test (%), dehydrogenase activity test (OD/g/mL), field emergence index and field establishment (%) decreased significantly and progressively as the ageing period increased. The electrical conductivity was negatively and significantly correlated with all seed viability and vigour parameters. Results also revealed that viability and vigour of seeds declined with faster rate in Lot-C (2½ years old seed). Among all the varieties/genotypes, genotypes DH 224 and DH 228 were found most promising for various parameters of viability and vigour.

Accelerated aging is one of the most useful tests used for the estimation of relative storability of different seed lots. In the present study, coriander seed viability and vigour of coriander seed was estimated by putting different seed lots under various period of accelerated ageing, i.e. 24, 48, 72, 96 and 120 hours at 40±1°C at 100% relative humidity during two consecutive years, i.e. 2017 and 2018. The study was carried out on the seeds produced under eighteen treatment combinations of organic manures (Farmyard manure and vermicompost), bio-fertilizers (Azotobacter and phosphate solubilizing bacteria) and inorganic fertilizers. Experimental results revealed that the co-inoculation of Azotobacter and PSB along with application of 100% recommended dose of nitrogen through vermicompost (VC) recorded significantly higher standard germination (%), seedling length (cm), seedling dry weight (mg), vigour index-I and vigour index-II at every stage of accelerated ageing. The electrical conductivity recorded was also minimum under this treatment which was due to cell membrane stability and decreased leakage of solutes from the seeds.

ABSTRACT The determination of the sanitary quality is important to diagnose if the commercialized lots are free of pathogens and to make a decision about the need for seed treatment. The objective was to evaluate the interference of fungi associated with coriander seed lots in their physiological performance and the effect of seed treatment with the fungicide Metalaxyl-m + Fludioxonil. The study was carried out in two steps. In experiment I, the physiological potential and sanitary characterization of 18 coriander seed lots were evaluated, using the tests, water content, tetrazolium test and health test. In experiment II, we evaluated the physiological performance of coriander seeds with and without fungicide treatment using the first count and germination test. Coriander seed lots showed high physiological potential, however, not all lots expressed their maximum potential in the germination test without treatment, due to the negative effect of fungi associated with seeds, mainly A. dauci and in association with A. alternata. There was an improvement in the physiological performance of coriander seeds treated with Metalaxyl-m + Fludioxonil fungicide.

Aim: Wheat varieties have been developed for yield improvement by modern plant breeding methods from the basic pedigree for long which brought about a restricted hereditary base. Therefore, the present study was designed to develop identification keys and characterize different wheat varieties on the basis of multiple traits. Methodology: Thirty-four Indian wheat (Triticum spp.) varieties released during different time scales were assessed for diversity through various approaches based on morphological, seed vigour, biochemical and molecular characterization.? Results: The results revealed that a considerable amount of variation was present in phenotypic characters such as flag leaf, plant height, spike and yield related characters. Seed vigour parameters included test weight, seedling dry weight, seedling length, accelerated ageing test and vigour indices showed significant variability among varieties. Dehydrogenase activity, tetrazolium test and electrical conductivity of seed leachates were also found worth studying for diversity. Molecular characterization included twenty-one SSRs selected after screening of 45, amplified 46 alleles, among them 42 alleles were polymorphic. PIC value varied from 0.1 to 0.65 and similarity coefficient extended from 0.34 to 0.87. Interpretation: Genetic diversity pattern analysis of genotypes based on their geographical origin did not show any clear relation, however characters like plant height, seed boldness and seedling vigour indices of varieties showed a trend with a chronology of their release. Different perspectives used in the study successfully categorized wheat genotypes into various groups.

An experimental study was conducted during 2011/2012 and 2012/2013 at Horticulture Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Monhanpur, Nadia, West Bengal, India, to evaluate the performance of fourteen different bush type French bean genotypes for seed yield and to study varietal characterization based on plant morphology. The genotypes, studied under this experiment were namely, Abhay, Shillong Local-3, Arjun, Selection-9, Arka Anoop, Arka Komal, Badshah, Anupam, Arka Suvidha, Falguni, Sonali, Local, Victoria and Vaishnavi-264. From overall point of view of the outcome of the experiment, it has been revealed that genotype with relatively bolder seeds with more number of seeds per pod, and higher bearing capacity per plant generally gives higher seed yield. Among the genotypes under study, Arka Suvidha was the best one as it produced the highest seed yield (2180.92 kg/ha) and relatively good plant vigour and fairly high seed vigour index (2944.38). Falguni and Mohanpur Local also can be considered promising once for seed production point of view.

The objective of this work was to establish the temperature and the period of exposure needed to perform the traditional accelerated ageing test with saturated NaCl salt solution on chickpea seeds. Eight seed lots from two cultivars, including four seeds each, were subjected to germination and vigour tests for initial characterization. Following the methodology of the traditional accelerated ageing test. The seeds were placed on stainless steel screens in boxes with 40 mL deionized water. They were kept at 41 and 45º Celsius for 24 and 48 hours. Furthermore, the accelerated ageing test using [40 g of NaCl in 100 mL of water, thus providing 76% of relative humidity in air] NaCl (salt) solution in place of the deionized water was performed. Aged seeds were sowed in germination paper and kept in a germination chamber at 41º and 45º Celsius. The evaluations were performed five and eight days after sowing. The statistical analysis was performed with a completely randomized design and four replications. The traditional ageing of both cultivars showed a water content higher than the tolerated limits at 48 hour period and 41 and 45 °C. In the saturated saline test, the cultivar BRS Aleppo produced consistent results at temperatures 45 °C for 24 h. The cultivar Cícero showed a low correlation with the initial characterization as the results of accelerated ageing. Thus, for ‘BRS Aleppo’, the recommended accelerated ageing methodology was application of saturated saline solution, when seed exposed to 41 °C for 24 hours with germination evaluation at the first count date. For 'Cicero', satisfactory results were not obtained, and new studies are required to establish a methodology.

Flax (Linum usitatissimum L.), grown throughout the world for millennia. It is a multipurpose agricultural crop that can provide food, fuel and fibre. An agro-morphological characterization based on 13 traits of 26 flax accessions was carried out during the Rabi season 2017-2018 at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Rangpur. The field experiment was laid out in a randomized completed block design having four replications. Flax seeds were sown in 3.0 m × 0.6 m plot with continuous line sowing (two lines). The seed germination (%) and vigour indices of all flax accessions varied from 44.1 – 77.7 and 44.1 – 119.4, respectively. A significant variation in all growth and yield attributing descriptors was observed except 1000-seed weight of flax. Among the accessions, BD-10708 possessed the highest seed yield (182.9 g plant–1) and yield attributing descriptors viz., number of capsules plant–1 (142) and seeds plant–1 (513) of flax. The performance of the local accesson Ulipur was observed poor compared to some of the test accessions of flax. Some of these flax accessions could be used as breeding materials in varietal developmental and improvement programmes with higher yield potentials of flax in Bangladesh.

Agricultural crops are facing a continuous threat due to biotic and abiotic stresses, thus, limiting the crop productivity, and thereby, threatening food security. Plant roots attract several kinds of microbes that induce resistance in plants against these stresses by enhancing the activity of the antioxidant enzymes, phenolic and other non-phenolic compounds, and thereby, have a beneficial effect on plants. Vast research has been carried out on biocontrol agents to manage soil-borne plant pathogens, but there has been limited success in the development of region-specific, commercially viable microbial inoculants. The present research was framed with a view to screen and evaluate native Pseudomonads from the rhizosphere of different crops in lateritic soils and their exploitation in biotic and abiotic stress management under the red and lateritic zone of West Bengal. In the lateritic area of West Bengal, the lowest pH as well as the highest culturable rhizobacterial population was found in the soil of Bankura. Among all the isolated rhizobacteria, 43.33% were found to be moderately antagonistic against three different soil-borne plant pathogens viz., Rhizoctonia solani, Sclerotinia sclerotiorum and Sclerotium rolfsii—while only 6.67% were found to be very highly antagonistic against these soil-borne plant pathogens. Augmented seeds of tomato, cowpea and French bean with native rhizobacteria enhanced the vigour index and 16.67% of the isolates were found to have a high value of vigour index in the normal and acid stress conditions. Based on acid tolerance, antagonistic activity and the seed vigour assay, a total of 13 isolates from 97 of lateritic area were selected. Out of the 13 selected isolates, 7 were positive for protease and lipase production, 8 isolates were positive for the production of HCN, siderophore and salicylic acid production and 9 isolates were found to be positive for IAA, phosphate solubilisation, amylase and chitinase production. Species of beneficial Pseudomonads such as Pseudomonas aeruginosa, P. fluorescens, P. Plecoglossicida, P. helmanticensis, P. geniculate, P. baetica and P. putida were found. Five isolates were used to study the effect on plant growth in terms of germination (%), root and shoot length, as well as fresh root and shoot weight and disease patterns in terms of pre- and post-emergence damping-off under the semi-field condition.

Seeds are the most effective and thriving propagation material of Salacia. As part of ex-situ conservation programme, four highly sought Salacia species, viz., Salacia brunoniana Wight & Arn., Salacia fruticosa Wall. Salacia malabarica Gamble and Salacia oblonga Wall. through fruit, seed and seedling characterization was carried out. For this, phenology and morphology of fruits and seeds with reference to polymorphism were documented. Effect of fresh and desiccated moisture content especially that of critical moisture were tested to understand the extent of viability of seeds. Since, these species became threatened in their natural habitat; attempts were made to standardize their seed germination characters and seedlings were raised. Seedling characters along with seedling vigour were documented up to 6 leaf stage and also an identification key was made based on their seedling characters which would aid in the demarcation of the species at their juvenile stage.

Biochar is considered one of the most promising long-term solutions for soil quality improvement, representing an ideal environment for microorganisms’ immobilization. Hence there is a possibility to design microbial products formulated using biochar as a solid carrier. The present study was aimed at development and characterization of Bacillus-loaded biochar to be applied as a soil amendment. The producing microorganism Bacillus sp. BioSol021 was evaluated in terms of plant growth promotion traits, indicating significant potential for production of hydrolytic enzymes, indole acetic acid (IAA) and surfactin and positive tests for ammonia and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase production. Soybean biochar was characterised in terms of physicochemical properties to evaluate its suitability for agricultural applications. The experimental plan for Bacillus sp. BioSol021 immobilisation to biochar included variation of biochar concentration in cultivation broth and adhesion time, while the soil amendment effectiveness was evaluated during maize germination. The best results in terms of maize seed germination and seedling growth promotion were achieved by applying 5% of biochar during the 48 h immobilisation procedure. Germination percentage, root and shoot length and seed vigour index were significantly improved when using Bacillus-biochar soil amendment compared to separate treatments including biochar and Bacillus sp. BioSol021 cultivation broth. The results indicated the synergistic effect of producing microorganism and biochar on maize seed germination and seedling growth promotion, pointing out the promising potential of this proposed multi-beneficial solution for application in agricultural practices.

The present work was conducted to study the genotypic variability of rice genotypes at the germination and seedling stages at different levels of salinity (0 M, 0.15 M, 0.2 M and 0.25 M NaCl). The results showed that increasing salinity decreased germination and seedling growth. Significant genotypic variability exists in the germination and seedling stages in response to different NaCl concentrations. Most of the genotypes showed more than 90% germination in the control, indicating good seed vigour. Two genotypes, VBR 638 (93%) and VBR 644 (84%), were selected as being tolerant to salinity at 0.2 M NaCl at the germination stage. Therefore, these could be used as source materials for genetic improvement for salinity tolerance at the germination stage. A considerable amount of genotypic variability was also found under control and saline conditions at the seedling stage with respect to the variables shoot height, root length, shoot and root dry weight. The high heritability observed for these variables offers good scope for genetic improvement for salinity tolerance both at the germination and seedling stages. The genotypes VBR 616, VBR 628, VBR 645, VBR 640, VBR 611, VBR 620, VBR 612, VBR 618, VBR 644, VBR 629, VBR 625 and VBR 630 were selected as being tolerant to salinity at the seedling stage.

Aim: Isolation, screening and characterization of beneficial rhizosphere bacteria associated with healthy (field-resistant) coconut palms in root (wilt) disease endemic hotspot areas of Kerala. Methodology: One hundred and ten rhizobacterial isolates associated with healthy coconut palms of root (wilt) diseased tract of Kerala were isolated and screened in-vitro for IAA production and solubilization of fixed forms of mineral nutrients. Seven isolates showing multiple phytobeneficial properties were characterized and the selected isolate was tested for its biopriming effect on maize. Results: Of the total isolates screened, 54 isolates produced IAA. Among the nutrient solubilizers, silicate solubilizers (57%) and phosphate solubilizers (48%) dominated. Of the seven isolates with multiple phytobeneficial properties, five rhizobacterial isolates belonged to Enterobacteriaceae family including three Enterobacter spp. The isolate T4HFB9 belonged to Acinetobacter sp. The green fluorescent Pseudomonas isolate K3HPSB2, showed 99% sequence similarity with Pseudomonas migulae. Seed biopriming of maize with Pseudomonas sp. strain K3HPSB2 recorded significant increase in germination percentage and seedling vigour index over untreated control. Interpretation: Disease-resistant coconut palms in RWD endemic tracts host a good proportion of phytobeneficial rhizosphere bacteria,with demonstrable multiple plant growth promoting traits. Multi-nutrient solubilizing Pseudomonas sp. with bioinoculant prospects has been selected for further studies on bio-priming for palm health management in RWD endemic tracts.

The descriptive and vegetative characterization of fifteen ecotypes of Trichosanthes cucumerina L (snake gourd) in Nigeria was carried out. The field study was done in two locations Markurdi and Umudike to evaluate the descriptive and vegetative characters of fifteen ecotypes of T. cucumerina from Middle Belt of the country, the South-South, South Eastern part and South Western part of Nigeria. Randomized Completed Block Design was adopted for the experiment at the exploration farm of Michael Okpara University of Agriculture, Umudike and Federal University of Agriculture, Makurd at the same growing season. Descriptive and vegetative analysis was done using Minitab 16. The qualitative vegetative characteristic of snake gourd accessions vigour levels ranged from low, moderate and high. Leaf colour was from deep/pale/light green, stem colour was light, pale and deep green. The mean of the vegetative characters ranged from 2.7660-1575 ±0.48-99; cumulative variation percentage 7.65-64.75;. The germination percentage of all the accessions was significant (p<0.05). CRS – IKM (100+00), Osu – OSH – 2 (91.67±4.82).EKT – OYE was higher than Ben-MKDI (58.36±8.34). The plant height among the accessions was not significant, block was significant (P≤0.05). Leaf sizes (cm) of all the accessions were not significant (P>0.05), while main vine length (cm) at 5% probability was not significant and their treatment interaction was insignificant (P>0.05). The main vein length was highest in ABI-UKW with 636.0±164.0, followed by EKI-OYE 514.0±84.3 and least from RIV-ELE 275.7±26.4. The fruit colour at ninety days (90) of ten (10) accessions of snake guard was orange green or strip orange green and remaining accessions was milky green or light green. The fruit shape was long, thick and cylindrical. The seed colour was speckled russet.

A key step in characterization of germplasm is the identification of phenotypic variation present in a given population. A study was carried out to determine the effect of different dosages of gamma rays (50 and 100Gy) on phenotypic variation using 21 standardized morphological descriptors of the UPOV Tea Test Guidelines. The trial comprised of open-pollinated seed stocks from six commercial tea cultivars namely TRFCA SFS150, TRFK 303/1199, EPK C12, GW Ejulu-L, TRFK 301/1 and TRFK 301/4 along with untreated controls. Data was collected for three seasons (dry, warm wet and cold wet) using five randomly selected plants from each treatment. Principle Component Analysis using 17 informative descriptors showed the first eight principal components accounted for 78% of the total variance, with 15 being highly informative. Cluster analysis further identified characters such as young shoot anthocyanin colouration at base of the petiole, leaf blade shape/color/length, shoot color/length, density of pubescence, plant vigour and density of branches as most discriminating descriptors resulting in four phenotypically well-defined groups. Most traits showed significant correlation, an indication that the traits could be used for indirect selection. The study provides a basis for rapid and early screening of base populations for identification of elite cultivars.

Phytotoxic activity ofOcimum tenuiflorum(Lamiaceae) plant extracts was investigated against the germination and seedling growth of cress (Lepidium sativum), lettuce (Lactuca sativa), alfalfa (Medicago sativa), Italian ryegrass (Lolium multiflorum), barnyard grass (Echinochloa crus-galli), and timothy (Phleum pratense) at four different concentrations. The plant extracts at concentrations greater than 30 mg dry weight equivalent extract mL−1reduced significantly the total germination percent (GP), germination index (GI), germination energy (GE), speed of emergence (SE), seedling vigour index (SVI), and coefficient of the rate of germination (CRG) of all test species except barnyard grass and GP of lettuce. In contrast, time required for 50% germination (T50) and mean germination time (MGT) were increased at the same or higher than this concentration. The increasing trend ofT50and MGT and the decreasing trend of other indices indicated a significant inhibition or delay of germination of the test species byO. tenuiflorumplant extracts and vice versa. In addition, the shoot and root growth of all test species were significantly inhibited by the extracts at concentrations greater than 10 mg dry weight equivalent extract mL−1. TheI50values for shoot and root growth were ranged from 26 to 104 mg dry weight equivalent extract mL−1. Seedling growth was more sensitive to the extracts compared to seed germination. Results of this study suggest thatO. tenuiflorumplant extracts have phytotoxic properties and thus contain phytotoxic substances. Isolation and characterization of those substances from this plant may act as a tool for new natural, biodegradable herbicide development to control weeds.

The organisation of germplasm into genetically divergent groups is of extreme importance for the development of hybrid varieties in which the identification and exploitation of heterosis is very important for the final result of breeding. It can also be beneficial for breeding of self-pollination varieties, clones and synthetics. The discovery of heterotic groups in standard grain quality maize significantly improved the process of testing. The improvement in sweet maize was relatively modest in comparison to standard grain quality maize due to a relatively narrow genetic base of sweet maize, then poorly defined heterotic relations, scarce sources of germplasm that satisfy commercial standards, poor seed vigour, low quality of root and stalk, as well as, a short period of time for the estimation of yield and quality. The efficiency of hybrid breeding programmes would be significantly higher if heterosis could be predicted prior to the evaluation in the field. The application of the multivariate analysis method to data of phenotypic characterization according to the UPOV Descriptor was an attempt to establish whether such a procedure can be beneficial for the determination of related groups and whether the phenotypic distance, obtained on the basis of a visual estimation of a plant group, can be an indicator of heterosis. Obtained results indicate that clustering is highly analogous to the pedigree. Since sweet maize breeders have at their disposal less significant genetic variability and search for the development and defining of heterotic groups, as such a procedure can be useful in both, the process of the hybrids development and the process of new inbreed development and genetic variability increasing. Certainly, further systematic studies aimed at this direction are necessary to reliably ascertain that the phenotypic distance is a justifiable indicator of heterosis.

The experiment was carried out during winter (rabi) season of 2016–17 and 2017–18 with 18 treatments comprising of inorganic fertilizers, biofertilizers and manures to compare the coriander (Coriandrum sativum L.) seed quality. The experiment was laid out in randomized block design with three replications. Results revealed that the co-inoculation of Azotobacter and phosphate solubilizing bacteria (PSB) along with recommended dose of nitrogen through vermicompost (T5) recorded significantly higher test weight, standard germination, seedling length, seedling dry weight, vigour index-I, vigour index-II, dehydrogenase activity, superoxidase dismutase, field emergence index and seedling establishment. The electrical conductivity was also recorded less in this treatment. The same treatment recorded significantly higher standard germination (31.50%), seedling length (14.09 cm), seedling dry weight (1.88 mg), vigour index-I (444), vigour index-II (59.25) and minimum electrical conductivity (696.92 μ S cm-1 g-1) after accelerated ageing of seed for 120 h at 40±1°C at 100% relative humidity. Suitable combination of organic manures and biofertilizers can be used to produce good quality coriander sees.

Coriander is one of the most widely used herb. Coriander generally grown for leaf and grain purpose throughout the world. Induction of mutation is considered to be effective in improving various characteristics in plants like seed germination, plant vigour, yield etc. In present study we used three different chemical mutagens Colchicine, Sodium azide (SA) and Methyl methane sulphonate (MMS) on four different varieties of coriander (Green wonder, Cross-91, Mrudul and Surabhi). The study was performed by exposing the seeds of four varieties of coriander (Coriandrum sativum L.) to Colchicine (0.01%,0.02%,0.03% and 0.04%), Sodium azide (SA) at (0.1%,0.2%,0.3% and 0.4%) and Methyl methane sulphonate (MMS) at (0.01%,0.02%,0.03% and 0.04%) respectively. The observations were made on seed germination in field and laboratory conditions and the observations on seedling height, number of primary branches and leaves were made in field conditions. All the mutagens significantly affect the germination and seedling growth. The study revealed that germination percentage, plant height, no. of primary branches and leaves decreased with increase in dose/concentration of mutagen. Among three different chemical mutagen we observed that colchicine is better mutagen for induction of mutagen after that sodium azide (SA) had good results for seed treatment. Some of the concentrations of methyl methane sulphonate (MMS) (0.01% & 0.02%) were better. Among all four varieties of coriander Cross-91 gave better result after that Mrudul and Surabhi respond well to some concentrations. We categories the effectiveness of mutagen to induce mutation in coriander as MMS>SA>Colchicine.

Experiment was conducted to evaluate the potential of selected plant growth promoting rhizobacteria (PGPR) towards enhancement of growth and yield of coriander crop (Coriandrum sativum L. cv Acr-1) under semi-arid condition in India. Six PGPR isolates showing in-vitro indole acetic acid production and tricalcium phosphate solubilization were the prime targets. These rhizobacterial isolates were evaluated for their ability to promote growth and yield of coriander under open field conditions. Highest seedling vigour index was recorded for B. aerophilus Cor-15 (1178.50) followed by B. megaterium (1125.20) and minimum was observed with control. The maximum total chlorophyll content was assayed with B. subtilis NRCSS-I which was 1.38 mg/g f wt and 1.30 mg/g f wt at 45 and 90 DAS respectively. The highest Pox activity was recorded with B. megaterium ISB28 (4.31 IU/min/g) in coriander shoot tissues at 90 DAS followed by B. aerophilus cor-15. At harvest stage, maximum plant height was recorded with B. aerophilus Cor-15 (84.36cm) which was at par with B. megaterium (82.90 cm). Coriander seed yield ranged from 1128.80 to 1650.94 kg/ha and the maxmum seed yield of 1650.94 kg/ha was recorded with B. aerophilus Cor-15 being at par with B. subtilis strains and the minimum in control. Maximum essential oil yield was recorded with B. megaterium ISB-28 (5.86 l/ha) followed by B. aerophilus Cor-15 (4.64 l/ha) and least was observed with control (3.09 l/ha).

The evaluation of seed quality parameters in coriander (Coriandrum sativum L.) under different irrigation regimes based on climatological approach and varied compositions of stress mitigating chemicals was carried out in the Laboratory of Seed Technology Research Unit, Department of Plant Breeding and Genetics, College of Agriculture, JNKVV Jabalpur (M.P.). The investigation consisted of four Irrigation regimes ie IW/CPE 0.6, 0.8, 1.0 and 1.2 and stress mitigating chemicals (Salicylic acid, thiourea and KNO3) with different concentrations. The experiment was laid out in Completely Randomized Design with three replicates during Rabi season (2020-21 and 2021-22). Marked influence of applied irrigation regime was exhibited by the seed lot collected from plots with IW/CPE ratio 0.8. The maximum standard germination of 82.89% was recorded in seeds from the plants which were grown in sufficient moisture content comprising of IW/CPE 1.2. Exogenous application of salicylic acid improved the seed germination parameters. The highest concentration was most effective in each treatment. Salicylic acid @ 150 ppm expressed better results. The results depicted higher test weight with 17.80g, higher plumule length of 15.75cm, radical length of 5.61 cm, seedling height of 21.36 cm, maximum magnitude 1841.64 and 28.33 of seed vigour index I & II respectively for Jawahar Dhaniya-10 was registered when the seeds harvested from plots with treatment combination of IW/CPE 0.8 along with foliar spray of salicylic acid @ 150ppm (I2C2). Higher content of 89.57% total solids was expressed under interaction of IW/CPE 0.6 with exogenous application of thiourea @ 500ppm (I1C3). Hence it can be concluded that treatment combination of IW/CPE 0.8 along with foliar spray of salicylic acid @ 150ppm (I2C2) ascertained better seed germination and quality attributes.

Plant growth promoting rhizobacteria (PGPR) are a group of useful bacteria that colonize the plant roots and significantly enhances the plant growth promotion. Keeping this in mind, an investigation was performed for the screening of potent PGPR strains for enhancing seed germination and vigour index of Hordeum vulgare (commonly called barley). Rhizobacterial strains were isolated and screened for various plant growth promoting traits, their effect on seed germination and vigour index of barley plant through pot trial, and resistant ability under various temperature and pH range. Based upon 16S rRNA sequencing data, Pseudomonas punonensis LMT03 (R1), Pseudomonas plecoglossicida R4, Pseudomonas aeruginosa DSM50071 (R2) and Alcaligenes faecalis (DBHU5) isolates were selected and showed positive result for IAA production, Phosphate solubilization, ammonia production, catalase activity, siderophore production and MR-VP test. Barley plants treated with P. punonensis and P. plecoglossicida both showed 94.44% of highest seed germination %, while P. aeruginosa and A. faecalis showed 83.11% and 77.33% respectively in comparison to the control plant shows which 49.99% seed germination only. These respective isolates also showed 2.57, 2.37, 2.0 and 1.69 fold of increase in vigour index as compare to the control plants. The above increase in fold in vigour index and seed germination is much higher as compared to earlier reports. Collectively, the data of current study underpin that addition of these PGPRs to barley rhizosphere appears a promising strategy to enhance root and shoot biomass of this important agriculture crop. To the best of our knowledge this is the first report demonstrating the effect of P. punonensis and P. plecoglossicda on barley crop.

We studied variations on different traits of (D.C.) Merr. in twelve provenances systematically from their source of origin to a controlled environment where representative seedlings were grown. Among the provenances, P1 gave the best result for seed traits including germination traits, P7 for pod traits and P10 for seedling vigour. Effects of seasonal distribution of rainfall and temperature on seed and pod traits were also determined by computing multiple regression analysis. The results displayed winter rainfall and summer temperature as the most important factor determining pod and seed traits. Latitude also significantly (Pâ<â0.001) affected PWT (râ=â0.52), SWP (râ=â0.46) and SW (râ=â0.50). A common garden study for germination and seedling growth indicated P1 and P10 provenance as the best among all. Seeds drawn from P10 gave the highest seedling vigour with an average growth rate of 0.61 cm/day from 90th to 180th day. Highest broad-sense heritability values (h) were observed in germination traits, followed by seedling collar diameter. The lowest h was observed for seedling height.Parkia timoriana22

Coriander (Coriandrum sativum L.) is an annual herbaceous plant and suffers from different fungal, bacterial andviral diseases of which stem gall caused by Protomyces macrospores is one among them. The disease appears in theform of tumour like swellings of leaf veins, leaf stalks, peduncles, stems and on fruits. The test pathogen was isolatedfrom infected stem and seeds and pure culture of the fungus was obtained on potato dextrose agar enriched with yeastextract medium. The colour of colony was creamy white initially which later turned light brown. Morphologicalcharacters comprising chlamydospores were studied which were yellowish brown, spherical or globose to oval,single-celled, smooth and measured 40-80 μ in diameter. For molecular characterization, genomic DNA was isolatedusing standard procedures and a region of the nuclear rDNA gene containing the internal transcribed spacer regionswas amplified from the genomic DNA. Phylogenetic tree showed that isolated strain A clustered close to Protomycesinouyei with 62% similarity only. Based on morphological characteristics, the isolated fungus was identified asProtomyces macrosporus but on the ITS sequences comparisons, strain A was similar to Protomyces sp. Pathogenicitytests showed that crushed powder of infected seed added to soil was better in disease development over mycelialsuspension and the symptoms of the disease appeared in 42.5 days.

Background: Sesbania species are widely used in different agricultural systems providing green manure, forage, firewood, pulp, food, landscape decoration, control of soil erosion and soil improvement. The biomass yield and yield contributing descriptors of Sesbania depend on different physiological traits. Methods: An experiment was conducted at Bangladesh Agricultural University to find out the morphological and physiological variability among four Sesbania genotypes. Sesbania species, viz. S. bispinosa, S. cannabina, S. sesban and S. rostrata, were used as experimental materials. Seeds were sown in 2.5 m × 2.0 m plots to maintain 200 plants m-2 following randomized complete block design with three replications. Seed length and width, 1000-seed weight, germination percentage, vigour index, seedling length and biomass yield parameters were recorded. Different growth data were recorded and physiological descriptors were calculated at every 10 days intervals up to 60 days after sowing (DAS). Result: The results revealed that the highest value of plant height, number of leaflets pair leaf-1, leaf length and biomass yield were found in S. bispinosa and the lowest in S. sesban at 60 DAS. Sesbania sesban produced higher biomass and studied growth descriptors up to 20 DAS and thereafter declined, however, other three species produced higher biomass and studied growth descriptors from 30 to 60 DAS.

Abiotic stresses in rice restrict the growth and potential of the crop hampering the production and productivity. Screening for abiotic stress tolerance was conducted for salinity and water stress (1% and 2%) during Kharif 2019 at Regional Agricultural Research Station, Maruteru, Andhra Pradesh, India. The physiological characterization of selected genotypes showed that among all treatments, seed germination, root length, shoot length and seedling vigour index was greater under control followed by 1% mannitol, 2% mannitol and salinity stress. The entries IET 27773, IET 27750 and IET 26861 performed well under moderate water stress (1% mannitol and 2% mannitol induced stress) and hence can be identified as relatively tolerant. Under salinity stress AC 1303 followed by IET 27750, IET 27772 and IET 27773 performed well. The above cultures can be used as physiological donors for respective stresses. The seedling vigour was highest in IET 27773 under all the stress treatments. IET 27750 and IET 27773 showed tolerance to both salinity and water stress. In the field experiment, IET 26961 (6230 kg/ha), IET 27768 (6060 kg/ha) and IET 27773 (6050 kg/ha) recorded the highest grain yield. Among all the genotypes tested, IET 27773 was found to be a good performing genotype as it exhibited tolerance to abiotic stress in lab conditions and recorded higher yields under field conditions.

Abstract Drought stress significantly affects chickpea production. The “QTL-hotspot”, a genomic region on pseudomolecule Ca4 in chickpea that harbours major-effect quantitative trait loci (QTLs) for multiple drought-adaptive traits, represents a promising target for improving chickpea drought adaptation. To investigate the mechanisms underpinning the positive effects of “QTL-hotspot” on seed yield under drought, this study introgressed the “QTL-hotspot” region from ICC 4958 genotype into five elite chickpea cultivars. The resulting introgression lines (ILs) and their parental lines were evaluated in multi-location field trials and semi-controlled experiments. The results showed that the “QTL-hotspot” region improves seed yield under water deficit by: (1) increasing seed weight, (2) reducing flowering time, (3) regulating canopy growth-related traits, and early vigour, and (4) enhancing transpiration efficiency. Whole-genome sequencing data analysis of ILs and parental lines revealed four genes underlying the “QTL-hotspot” region associated with drought adaptation. We validated diagnostic KASP markers closely linked to four genes using ILs and parental lines for deployment in chickpea breeding programs. The CaTIFY4b-H2 haplotype of a potential candidate gene CaTIFY4b was identified as the superior haplotype for 100-seed weight. The candidate genes and superior haplotypes identified in this study could serve as direct targets for genetic manipulation and selection for chickpea improvement.

An experiment was conducted to evaluate the growth promotion in isabgol (Plantago ovata Forsk.) with native rhizobacteria strains (ISB-2, ISB-5, ISB-8, ISB-9, ISB-10, ISB-125, ISB-15 and ISB-28) isolated from the rhizospheric soils collected from western semi-arid region of India. These isolates were tested for their indole acetic acid production, insoluble phosphate solubilization and ability to promote germination of isabgol seeds under controlled conditions. Three rhizobacterial isolates (IBS-5, IBS-9 and IBS-28) were found promising towards enhancing the growth and yield of isabgol plants. The isolate ISB-5 was identified as Azotobacter vinelandii, ISB-9 as Pseudomonas stutzeri, and ISB-28 as Bacillus aryabhattai based upon their biochemical and molecular characterization. The highest seedling vigour index was recorded for B. aryabhattai (316.52±3.02) followed by A. vinelandii (310.22±7.56) and the lowest seedling vigour was recorded with ISB-10 which was found to be at par with control. The maximum shoot dry weight at harvest was recorded with B. aryabhattai (2.33g) being at par with P. stutzeri and the minimum shoot dry weight was for control. The highest seed yield per plant (0.72 g) was observed with B. aryabhattai followed by A. vinelandii(0.61 g).

The objective of the present study was to produce a pheno-morphological characterization of 13 faba bean lines selected by the Institute of Arid Regions from 42 local populations. The pheno-morphological variability of these lineages was observed and followed from planting through to seed maturity by biometric measurements and by qualitative evaluations on different plant parts. Morphological characteristics were described by using the UPOV (2000) descriptor. The analysis of results made it possible to distinguish between 2 groups based on precocity and hundred-seed weight. The first group was represented by line 8 which differs from others by the fact that it was the earliest and had the highest one hundred-seed weight. The second group was divided into 3 subgroups that differed in terms of plant vigour and productivity. The first subgroup was characterized by a lower number of flowers per raceme, a hundred-seed weight average ranging from 162.96 g to 165.24 g and a highest number of seeds per pod. This first subgroup contained the lines 5, 10, 11, 12 and 13. The second subgroup included lines 6, 7 and 9 which were the most homogenous on 50 % owering date, plant height and length of lea et. The latter subgroup included the lines 1, 2, 3 and 4, characterized by a highest number of pods per plant, number of stems per plant, and number of flowers per raceme. These lines should be preserved and valued for the varietal improvement programs of Vicia faba. Successive selection should be practiced until a more productive synthetic variety is obtained that is better adapted to the dry conditions of South Tunisia.Key words: Phenology, agromorphology, characterization, Vicia faba

A field survey was conducted in 12 districts of Assam viz., Jorhat, Golaghat, Nagaon, Marigaon, Goalpara, Dibrugarh, Tinsukia, Lakhimpur, Dhemaji, Sivsagar, Kamrup and Barpeta. A total of 92 root samples were collected and 37 bacterial isolates were isolated from commercial banana cultivars. The culture filtrates extracted from 37 endophytic bacterial isolates, were screened against southern root-knot nematode, Meloidogyne incognita in vitro and under pot culture studies. The five bacterial isolates viz., EB4, EB8, BC1, BC11 and BC12 showed 100% inhibition of egg hatching and juvenile mortality of M. incognita with an exposure period of 48 and 72h. On seed bacterization, with these five promising isolates, two isolates viz.EB4, BC1 significantly enhanced germination percentage (33.33, 25.31%) and vigour index (75.5, 64.39%) of paddy, receptively. The potential bacterial isolates viz., BC1 and EB4 were identified as Lysinibacillus sp. and Pseudomonas sp., respectively , based on the morphological phenotypic and biochemical characterization. The pot culture experiment revealed that the bacterial endophytes viz., Lysinibacillus sp. (BC1) Pseudomonas sp. (EB4) significantly reduced the soil (61.64, 56.71%) and root nematode population (77.29, 68.87%), number of adult females (73.97, 69.89%), egg masses (85.63, 80.11%) and root-knot index (1.33, 1.67) of M. incognita compared to untreated control. The bacterial endophytes viz., Pseudomonas sp. (EB4), Lysinibacillus sp. (BC1) were also significantly increased the growth parameters viz., shoot length (43.33, 39.18%), and root length (78.24, 59.26%) and pesudostem girth (58.38, 52.13%).
