Keeping consideration over this experiment was designed to study genetic variability and heritability under non-irrigated and irrigated condition on some morphological and quality traits an experiment on Indian mustard (Brassica juncea L.Czern & Coss), was conducted by accommodating 20 genotypes, from various Rapeseed & Mustard centres located across country, randomly in three replications during Rabi 2016-17 in Randomized Complete Block Design (RBCD), one subjected to a drought regime inside the Rainout shelter under non-irrigated condition which was also devoid of rainfall and another one provided with normal irrigated field condition in Dr. Rajendra Prasad Central Agricultural University , Pusa, Samastipur. Analysis of variance for the studied traits revealed considerably exploitable variability. Out of 20 genotypes under both non-irrigated as well as irrigated condition, Rajendra Suphalam showed tolerance towards water stressed condition and performed well in terms of productivity in an irrigated situation for all the traits. PKRS-28 identified as tolerant genotype under non-irrigated, and Pusa Mahak as well suited under an irrigated condition in terms of flowering-maturity, siliqua characteristics and yield contributing traits. Under both conditions, high heritability coupled with high GAM for traits namely, HFPB and SBP-1 which were indicative of preponderance of additive gene action for expression of these traits hence are acquiescent for simple selection. The height of first primary branch and secondary branches per plant due to wide variability, meagre environmental influence along with high heritability and genetic advance suggested the exploitation of these traits for the further breeding programme as these traits are fixable in nature can be utilized in further segregating generations.The initiation of primary branches from the lowest position of the plant can accommodate number of branches and also provides a way to utilize the non-usable portion of the mustard plant from the base up to 55-60 cm.

Wilczek) were conducted on 15 Mung bean genotypes at Horticulture Research Farm, SGT, Gurugram, Haryana during kharif 2021. The study was set up in a Randomised Block Design with three replications and focused on variability of 16 morpho-physiological characters. The analysis of variance revealed extremely significant variations across accessions for all characteristics. There is potential for improvement in traits with high mean and high range, such as Days to 50% blooming, Days to initial flower opening, Days to cessation of flower, Relative water content, Biological Yield, Harvest Index, and Grain yield per plant. IPM205-7 demonstrated advantage in terms of early blooming as well as a number of yield-related features like height of the plant, number of secondary and primary branches per plant, number of pods, root length, and number of roots, biological yield, harvest index, and grain yield per plant.

Their symbiotic relationship with plants has evolved over millennia, resulting in co-adaptations that facilitate the reproductive success of many plant species. This review sheds light on the multifaceted interactions between insect pollinators and plants, emphasizing their contributions not only in crop production but also in maintaining broader ecosystem services. The importance of insect pollinators, such as bees, butterflies, beetles, and flies, among others, is highlighted by their direct influence on the yield and quality of many crops. Notably, global agricultural sectors like fruits (e.g., apples and berries) and nuts (e.g., almonds) heavily depend on these insects for pollination. In economic terms, pollinators contribute substantially, with their decline potentially resulting in significant economic losses globally. Bey...

It is an unexplored crop with a great economic potential. The present study deals with assessment of genetic diversity in the crop. Twenty two RAPD and 18 SSR primers were used for analysis of the 47 different sesame accessions grown in different agroclimatic zones of India. A total of 256 bands were obtained with RAPD primers, of which 191 were polymorphic. SSR primers gave 64 DNA bands, of which all of were polymorphic. The Jaccard& s similarity coefficient of RAPD, SSR, and pooled RAPD and SSR data ranged from 0.510 to 0.885, 0.167 to 0.867, and 0.505 to 0.853, respectively. Maximum polymorphic information content was reported with SSRs (0.194) compared to RAPDs (0.186). Higher marker index was observed with RAPDs (1.426) than with SSRs (0.621). Similarly, maximum resolving power was found with RAPD (4.012) primers than with SSRs (0.884). The RAPD primer RPI-B11 and SSR primer S16 were the most informative in terms of describing genetic variability among the varieties under study. At a molecular level, the seed coat colour was distinguishable by the presence and absence of a group of marker amplicon/s. White and brown seeded varieties clustered close to each other, while black seeded varieties remained distanced from the cluster. In the present study, we found higher variability in Sesamum indicum L. using RAPD and SSR markers and these could assist in DNA finger printing, conservation of germplasm, and crop improvement.

Water shortage is a deleterious consequence of both population growth and climate change and is one of the most severe factors limiting global crop productivity. In order to study correlation and cause effect of deficit irrigation on some physiological traits on yield an experiment on Indian mustard (Brassica juncea L. Czern & Coss), was conducted in Randomized Complete Block Design (RBCD) accommodating 20 genotypes, from various Rapeseed & Mustard centres located across country, randomly in three replications during Rabi 2016-17, one subjected to a drought regime inside the Rainout shelter under residual moisture condition and another one provided with normal irrigated field condition in Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur. Analysis of variance revealed considerably exploitable variability for all the 15 traits. Under both conditions of phenotypic correlation revealed that grain yield per plant showed significant and positive correlation with RWC, LMSI, CC, CA, PERO, PRO, RGR, LAI, SLW, OY except ELWL. Phenotypic path coefficient under both condition revealed that all the physiological parameters showed the low direct effect except oil yield showed high direct effect on grain yield per plot. This indicated that improvement in all the physiological parameters which showed significant positive effect and direct effect on grain yield per plot will ultimately enhances the grain yield.

Correlation studies indicated that, grain yield per plot exhibited significant and positive association(with plant height (0.28,0.63), panicle length (0.39,0.69), number of tillers per plant (0.35,0.60), number of spikelets per panicle (0.62,0.49), relative water content (0.36,0.72), maximum root length (0.44,0.72), flag leaf area (0.58,0.73), harvest index (0.61,0.27), chlorophyll content (0.68,0.59) and 1000 grain weight (0.58,0.68), at phenotypic level under both normal and aerobic condition. Path analysis revealed at genotypic level that under aerobic and normal condition traits like days to fifty percent flowering (0.487), no. of spikelet per panicle (0.572), no. of tillers per plant (0.688), relative water content in flag leaf (0.98) and maximum root length (0.832, 1.18) had highest positive direct...
