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.

The present investigation comprised of 20 varieties of coriander (Coriandrum sativum L.) was undertaken to characterize the varieties based on morphological and molecular markers including protein, isozymes and random amplified polymorphic DNA (RAPD) markers. All the varieties were also studied to know the vigour potential and also to find out suitable predictor for seedling establishment. The study revealed that morphological characters like days to 50% flowering, plant height, plant appearance, days to maturity, number of umbels per plant, number of umbellets per umbel, number of seeds per umbel and seed yield per plant were found important diagnostic characters for categorizing these varieties. Seed characters such as seed size, seed shape and test weight clearly differentiated the varieties into different groups. Total soluble seed protein analysis using SDS-PAGE revealed that varieties namely Sadhna, Sindhu, RCr-436 and RCr-684 gave different banding patter from rest of the varieties showing dissimilarity from them. Similarly, superoxide dismutase isozymes analysis using native PAGE revealed that varieties like CS-6, Sindhu and Swathi gave different banding pattern from rest of the varieties and showed dissimilarity from other varieties. However, peroxidase isozyme analysis showed lack of polymorphism in bands and hence, it could not differentiate the coriander varieties. Twenty RAPD primers were used to assess molecular polymorphism in the coriander varieties. A total of 90 bands were obtained from twenty random primers and out of that 73 bands were polymorphic while 17 bands were monomorphic resulting in 81.1 per cent polymorphism among the varieties. The majority of bands were polymorphic (73 bands, 81.1%) and only 17 bands (18.9%) were monomorphic. Out of twenty primers, four primers gave 100 per cent polymorphism. A few primers produced specific allele/DNA band which distinguished the variety from rest of the varieties. Results showed that RAPD bands were more effective and clearly differentiated varieties from each other but no primer gave polymorphism with all the varieties simultaneously. Maximum vigour potential was shown by GC-2, CS-6, H. Anand, H. Surbhi, RCr-435, RCr-436 and RCr-480 varieties, which showed superiority for almost all vigour parameters. Standard germination, tetrazolium test, and Accelerated ageing test were found the most suitable predictors for seedling establishment in coriander.
