Abstract:
Central Cotton Research Institute (CCRI), Multan, Pakistan has evolved an upland cotton cultivar “Cyto-124” through introgression for Cotton Leaf Curl Virus (CLCuV) resistance. It was developed through crossing [{2(G. hir. x G. ano.) X 3G. hir.} x {2(G. arbo. x G. ano.) x 2G. hir. It was tested for seed cotton yield in varietal trials, and zonal varietal trials at Govt. and farmer fields. Cyto-124 gave 37.1, 19.9 and 22.4% higher yield as compared to three standards MNH-786, CIM-554 and CRSM-38 respectively in varietal trials whileCyto-124 had seed cotton yield of 3075 kg ha-1 in-contrast to 2919 kg ha-1 of CIM-573 in zonal trials. Cyto-124 produced more seedcotton yield (SCY) than the standards for two consecutive years (2013 & 2014) in National Coordinated Varietal Trial (NCVT). In NCVT during 2013-14, this strain had a maximum yield of 2244 kg ha-1 compared with 1326 kg ha-1 of standard variety CIM-573 in Punjab. The virus data taken in NCVT indicated that minimum disease incidence (27.9%) was recorded in Cyto-124 making it the more tolerant strain against CLCuV. The approval of this CLCuV resistant cultivar will considerably contribute a lot in the revival of cotton.

Abstract:
SUMMARYWithin the context of participatory varietal selection of peanut (Arachis hypogaea L.) in East Timor, this study investigated an approach to identify yield determinants in farmer-managed varietal trials in a type of exploratory agronomy. A singular increase of 47% in peanut on-farm productivity by variety Utamua over local varieties was recorded across agro-ecologies over 616 farmer-managed trials in five cropping seasons. Utamua has larger (c. 70%) seed than local, which resulted in poor germination initially. Farmers then started seed priming, and, by the last two seasons’ trials, 50% of farmers with on-farm trials seed primed. The volume of trials allied with detailed recording of agro-ecological, household and management conditions allowed the identification of factors affecting yield, such as seeding arrangement (two seeds/hill more productive than one seed/hill) and soil pH (pH 7–8.5 more productive than lower pH), using an unbalanced ANOVA design. Farmer innovations in management could be identified within varietal trials highlighting future agronomic possibilities.

Abstract:
Abstract Mungbean is one of the major food legume and cash crops grown and consumed by small holder farmers under rain-fed conditions in Eastern Indonesia. However, the mungbean productivity has been low, less than 1 ton ha−1 due to a number of reasons including poor awareness about new varieties and skills of crop management. Two trials: varietal trial and management practices were conducted at Malaka District, East Nusa Tenggara during wet season 2008. The varietal trial in six sites resulted in identification of Sriti, Murai, Betet, and Vima 1 varieties had high productivity (1.1-1.5 t ha−1) with single harvest, shorter maturity, compared to the local varieties which were characterized by lower productivity (1.0-1.1 t ha−1), multiple harvests and longer maturity. The management practices found that selected varieties in combination with improved technology gave doubled seed yields compared to the yields when grown using local technology. These activities showed a reliable pathway to increase productivity of mungbean at small holder levels. The varietal and agronomic management trials demonstrated the impact of the technologies on mungbean productivity at small holder levels and identified future needs to sustain food productivity in remote regions on Eastern Indonesia.

Abstract:
SUMMARYUse of a one-dimensional neighbour method of analysis in 1019 variety trials of a range of crops conducted by plant breeders in four states of Australia in 1985–87 resulted in an average reduction of 42% in variances of varietal yield differences compared with conventional randomized complete block analysis. Of these trials, 219 were designed as square, rectangular or generalized lattices and the average reduction in variances of varietal yields with incomplete block analysis and recovery of interblock information was 33%. The results emphasized that plots should be wide enough to avoid interplot competition, and that neighbour analysis is of most benefit in trials with short plots or when the field layout has many plots in a row.

Abstract:
The present study pertaining to the identification of high yielding quality protein maize genotypes was conducted under coordinated varietal trials (CVT) at Khumaltar (Lalitpur) and Kabre (Dolakha) from 2011 to 2012 summer season and under coordinated farmers' field trials (CFFT) at Lumle (Kaski), Kimugaun (Dailekh) and Kabre (Dolakha) in 2011 summer season and at Dailekh and Kabre in 2012 summer season. The results of these trials showed that the genotypes namely Obatanpa followed by S99TLWQ-B and S01SIYQ produced the highest grain yield under coordinated varietal trials and genotypes namely S99TLYQ-B followed by S01SIWQ-3 and Poshilo Makai-1 produced the highest grain yield under coordinated farmers' field trials across testing sites and years. It is suggested that the superior genotypes derived from CFFT could be released and then recommended to farmers of mid hills of Nepal.International Journal of Life Sciences 10 (1) : 2016; 7-9

Abstract:
Downy mildew is a major concern to broccoli growers in the Sonoran Desert. Control measures include wide use of fungicide applications to prevent economic damage. Recent removal of EBDC type fungicides from the market and restrictions imposed on other registered materials has increased interest by growers and broccoli breeders in developing varieties tolerant to downy mildew. From 1984 to 1989 varieties were evaluated for tolerance to downy mildew in unreplicated trials conducted in commercial fields. In 1990, named varieties of current interest in desert production which showed tolerance to the disease in the previous trials were compared to standard varieties used by the industry. Varieties were replicated four times using a randomized complete block design. A rating scale from 1 to 5 was used to describe the severity of foliar lesions. The varieties Everest, Zeus, Legend, Pirate and Sultan showed significant tolerance when compared to the more susceptible varieties Arcadia, Emerald City, Emperor, Greenbelt, Packman, Commander, and NS 649.

Abstract:
A number of improved pipeline varieties of sorghum including PARC SS-1, PARC SS-2 and PARC Ss-15 were planted in various agro-ecological zones of Pakistan for 2 years (2004 and 2005). The participatory Mother-Baby Trial methodology was used for the first time in Pakistan for varietal evaluation and selection. Six varieties of sorghum were evaluated along with the local checks. In general, the pipeline varieties developed at the National Agricultural Research Centre had a yield advantage of 15 to 20% over the local checks and other improved varieties included in the trial. The farmers were involved in the varietal selection process. These varieties were selected by the farmers on the basis of maturity, higher yield, resistance to leaf blight and red rot diseases, drought tolerance, and the dual (grain cum fodder) nature of the varieties. Based on the evaluation and selection, these varieties are being released for general cultivation in various ecologies. The results from participatory trials on various agronomic aspects are presented and discussed in this paper.

Abstract:
SUMMARYOn-farm participatory varietal selection (PVS) trials are often of two types: mother trials (with all of the entries) and baby trials (each having one, or very few of the entries from the mother trials). We conducted PVS trials on 17 wheat varieties in 12 villages of four districts of Bangladesh over three years but the data were highly unbalanced. Both quantitative and qualitative traits were measured in the on-farm trials. The factors in the trials were both fixed effects (varieties and districts) and random (years and farmers). We used the residual or restricted maximum likelihood (REML) analysis for the mixed model for quantitative traits. For qualitative data on farmers' perceptions, logistic regression procedures were used that are equally applicable to balanced and unbalanced data sets. The REML analysis provided adjusted mean values for quantitative traits for all the varieties, for the mother and baby trials separately, using the data from all years and all locations. It identified varieties BAW 1006 and BAW 1008 that yielded 19–30% more than the control Kanchan and also had a higher 1000-grain weight, were at least as early to flower and had a high overall ranking by farmers in the mother trials. The logistic regression analysis of perception data agreed with the results of the REML analysis as these varieties were most preferred by farmers for grain yield, earlier maturity and better chapatti making quality. The less labour-intensive method of recording qualitative perceptions can usefully replace actual yield measurements, particularly when validated by other participatory measures such as intended and actual adoption. In 2005, BAW 1006 was released as BARI Gom 23 or Bijoy and BAW 1008 as BARI Gom 24 or Prodip for the whole of Bangladesh. The validity of the results of the REML analysis was confirmed by the high early adoption trends of the identified varieties. Since REML is an effective analysis for unbalanced PVS trial data using a mixed model, its wider use by researchers would increase the value of the PVS process.

Abstract:
Abstract Chickpea has a high yield potential, nutritional importance and diversity of use. A mutation breeding programme was undertaken at Bangladesh Institute of Nuclear Agriculture (BINA) with a view to developing early-maturing, large-seeded and high-yielding varieties of chickpea. Seeds of the popular chickpea variety 'Desi Binasola-2' were treated with different doses of gamma-rays (200, 300 and 400 Gy). The treated seeds were grown in batches according to dose for raising the M1 generation. M2 seeds were collected from individual M1 plants and subsequently grown in plant-progeny rows in the M2 generation and selections were made from the M2 families. Only 85 plants were selected from the M2 population and these were grown in the M3 generation. The mutant 'CPM-kabuli' and 28 other mutants were selected from M3 and were grown in the M4 generation. Only five mutants, including 'CPM-kabuli', were selected from M4 and were grown in M5. The selected mutant 'CPM-kabuli' along with check varieties were put into preliminary yield trials. Finally, the mutant lines were evaluated, with respect to two check varieties, in advanced, zonal-yield, on-farm and on-station trials in successive generations. All the selected mutant lines were grown at different locations in Bangladesh to observe the yield and other characteristics. The performance of the mutants was evaluated under two management practices: research management and farmers' management. Contrary to its parent, 'CPM-kabuli' was found to be tolerant to root rot and Botrytis grey mould, and also showed greater tolerance to pod borer insect-pest infestation than other mutants and check varieties. The main improved attributes are a cream seed coat colour, which reflects kabuli type, larger seed size and higher seed yield. The mutant 'CPM-kabuli' matures in the range of 115-125 days and is high yielding (1.7 t/ha). Considering all these, the bold Kabuli type chickpea mutant 'CPM-kabuli' was registered as the variety 'Binasola-9' for commercial cultivation during 2017 and is suitable for farmers in drought-prone areas in Bangladesh.

Abstract:
AbstractDuring the past few years, we have been witnesses of a critical juncture in the history of cancer therapy; indeed, immunotherapy has been introduced initially in melanoma trials and has been gradually incorporated in the treatment algorithm of a variety of malignancies in multiple settings. Immune checkpoint inhibitors (ICIs), the most widely used immunotherapy drugs, are monoclonal antibodies that target specific immune checkpoints such as Programmed Cell Death-1 (PD-1) and Cytotoxic T-lymphocyte-Associated protein 4 (CTLA-4). Response to ICIs is characterized by marked durability, but despite a great enthusiasm that accompanied the results of phase III clinical trials, a large proportion of patients do not derive benefit from ICIs. In addition, treatment with ICIs may be associated with several atypical patterns of response, such as pseudoprogression and hyperprogression. In this chapter, we aim to illustrate current data on patterns of response to immunotherapy with focus on head and neck cancer.

AbstractSince approved by the FDA for the treatment of glioblastoma brain cancer in 2015, tumor-treating fields (TTFields) have rapidly become the fourth modality to treat cancer, along with surgery, chemotherapy, and radiation [1]. TTFields are now in clinical trials for a variety of cancer types. While efficacy has been proven in the clinic, the higher efficacy is demonstrated in vitro and in animal models, which indicates much greater clinical efficacy is possible. To attain the great promise of TTFields, uncovering the mechanisms of action (MoA) is necessary.

Abstract:
AbstractThe eye is the organ in charge of vision and, given its properties, has become an excellent organ to test genetic therapies, including antisense oligonucleotide (AON) technology. In fact, the first AON receiving FDA and EMA approval was meant to treat an eye condition. Currently, dozens of clinical trials are being conducted for a variety of subtypes of inherited retinal disease. Although most of them are based on gene augmentation therapies, a phase 3 and two phase 1/2 clinical trials using AONs are ongoing. Since the retina is a layered structure of nondividing cells, obtaining human retinal tissue and expanding it in the lab is not possible, unless induced pluripotent stem cell technology is used. Mouse models have helped to elucidate the function of many genes, and the retinal structure is quite similar to that of humans. Thus, drug delivery to the mouse eye can provide valuable information for further optimization of therapies. In this chapter, the protocol for intravitreal injections of AONs is described in detail.

Abstract:
Yellow rust, caused by Puccinia striiformis Wes. is one of the most significant diseases constraint to winter wheat production in the world. Since 2011 in Europe have appeared distinct new races – Warrior, Kranich, Warrior (-) that have caused wide epidemics on different cultivars of wheat. Grain yield losses can be prevented by using a combination of varietal resistance and fungicides. Information on wheat variety susceptibility to local yellow (stripe) rust Puccinia striiformis Wes. races can help to reduce the risk of yield losses in high disease pressure situations. Field trials with eight most popular and perspective winter wheat varieties in Latvia were established in the North-Western part of Latvia (Stende Research Centre) in autumn of 2016. The trial was designed as two randomized complete blocks (treated and untreated) and data were statistically interpreted. Two applications of fungicides at BBCH 29-32 by T1 (prothioconazol 53 g L-1, spiroxamin 224 g L-1, tebucanazole 148 g L-1) and at BBCH 37-39 - T2 (bixafen 65 g L-1, prothioconazol 130 g L-1, fluopyram 65 g L-1- 1.5 L ha-1) were used to control the YR. Yield and 1000 kernel weight (TKW) were determined. Preliminary results indicated the difference between genotypes resistance/susceptibility to YR. The severity of infection level was 1- 80% depending on genotype resistance. Application of fungicides increased grain yield by 2.9 % to 33.0% and TKW by 3.4% - 33.2 % depending on variety. Observations showed the difference in the occurrence of symptoms on YR in different varieties of winter wheat under conditions of 2017 in Stende.

Abstract:
The speed/power characteristics of ships have always been at the core of ship design. To prove contractually agreed values, speed trials are conducted by the yard prior to delivery of the ship to the owner. In the past schedule integrity of the vessel was often the most important factor for the speed requirement. Today, owners and operators are keen to reduce fuel consumption to decrease operational costs. So far a variety of methods for conducting and analyzing speed/power trials have been used by shipyards. With the assistance of the Sea Trial Analysis-Joint Industry Project, ITTC developed guidelines for the execution and analysis of speed/power trials compliant with IMO EEDI. The need to reduce fuel costs and exhaust gas emissions including the upcoming environmental regulations such as EEOI by IMO urge for reliable monitoring of ship performance in service conditions. This requires accurate information of the speed through water. Although the speed log is one of the oldest instruments on board it is not considered the most reliable one. Results of an extensive monitoring campaign on board a 1800 TEU container vessel equipped with six speed logs within SPA-JIP will be presented. The state of art of performance monitoring will be presented.

Abstract:
Our aim was to create a competitive variety of essential oil Rose L. with a high yield of concrete. Studies were carried out at the experimental plots of FSBSI “Research Institute of Agriculture of Crimea” in 2011-2015. As a result of long-term breeding work, a new variety ‘Zolushka’ was created. Rose blooms yield reached 39.2±5.8 cwt/ha; the amount of concrete – 8.68±1.96 kg/ha. According to competitive variety trials, ‘Zolushka’ exceeded varieties ‘Lany’ and ‘Lada’ in flower (petals) yield by 17.2 and 14.3 cwt/ha; in yield – by 3.74 and 2.92 kg, respectively.

Abstract:
Abstract Pipeline integrity management involves the analysis of pipeline condition information (e.g., pipe size, existence, and size of features), operational/environmental conditions and line pipe material properties in engineering assessment (fitness-for-purpose) tools to evaluate operational risk. While nominal or minimum specified material properties and SCADA reported, design or estimated operational loading conditions can be considered, pipeline operators depend heavily on pipeline condition data from in line inspection systems. This paper will present the details of performance trials supported by the Pipeline Research Council International (PRCI) evaluating the ability of ILI systems to provide pipeline condition information for dents with coincident or closely aligned features. A set of sample dent features were prepared along with a trial protocol and performance metrics beyond those presented in API 1163 that were used to characterize performance. The ILI system pull and pump through trials of magnetic, ultrasonic and caliper-based ILI technologies from seven ILI Service Providers were used to consider detection, identification and sizing performance for isolated corrosion features, dents with variety of shapes including those without coincident features and those with corrosion, gouges, cracks, cracks and corrosion. The effect of dents on the ILI system detection, identification and sizing of the coincident features was evaluated. The presentation will describe trial protocols including new feature characterization techniques that considers the position of the coincident feature in the dent pipe wall deformation. The trial results include consideration of various technologies, the effect of speed and relative position of the dent and coincident feature on probability of detection, identification, and sizing accuracy by considering unity plots and observed statistical variation and trends. The final objective of this work was to report on the performance of ILI systems in detecting, characterizing, and sizing dents with coincident features such that this information can be used to support the pipeline integrity management process and provide feedback to ILI Service Providers to support advancement in technology development. The results of this work described in this paper provide confidence that ILI systems are capable of reporting dents and any coincident features to support fitness for service evaluation or integrity management.
