Oilseed Brassica plays the important role in Indian agriculture in relation to oil production. The major insects in Brassicas are Lipaphis erysimi, Bagrada hilaris, Athalia lugens proxima (Klug), Chromatomyia horticola Goureau, Pieris rapae, Bagrada cruciferarum Kirkaldy are of practical importance. Out of these, the Lipaphis erysimi (Kalt.) [mustard aphid], a part of family Aphididae with order Hemiptera leads to great yield losses in rapeseed-mustard. To overcome this problem, the easiest solution is to grow resistant and tolerant varieties. The screening is done on the basis of aphid infestation index scale for categorization of the genotypes into resistance and tolerance. Experiments were carried out at the experimental farm of Division of Plant Breeding and Genetics, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology, Jammu during rabi of 2017–18 and 2018–19 to evaluate mustard germplasm against Lipaphis erysimi and selecting the resistant genotypes of Brassica for its cultivation and expansion purposes. A total of fifteen cultivars were evaluated based on population buildup of mustard aphid and infestation index. The genotypes RSPN-28, CNH-11-13, RL-1359, HNS-1101, GSC-101, CNH-11-2 and HNS-1102 were found moderately resistant during the rabi 2017–2018 and during rabi 2018–2019, due to weather conditions only two genotypes CNH-13-2 and RSPN-29 were found moderately resistant and susceptible against aphid infestation.

An experiment was carried out during 2017-2018 to estimate fatty acids and the oil content (OC) in fifteen Brassica napus genotypes. The quality parameters of oil include fatty acids (FA) and the oil content (OC), important trait differed significantly (p?0.05) amongst the Brassica species genotype. Among the genotypes, significant differences were noted for the fatty acids and the oil content (OC). In Brassica napus seeds oil content varies in between the range of 37.45–41.86% respectively. The saturated fatty acid (SFA) includes the Palmitic acid (PA) varied in between the range of 2.68–4.43% and oleic acid (OA) content results lied between 8.88-56.18% respectively. In linoleic acid (LA) and linolenic acid (LNA), presence of significant differences (p?0.05) was there. The content of linoleic acid (LA) lies in the range between 12.97- 17.98% respectively and linolenic acid (LNA) content varied from 13.41-23.42% respectively. The stearic acid (SA) content varied from1.20-1.66 respectively. Erucic acid, another essential trait, significant differences were noted amongst the Brassica species genotypes i.e. 12.96-48.80%. The minimum erucic acid (EA) content was noted in GSL-1 genotype and the genotypes namely RSPN-28 and CNH-13-2, EC552608, GSC-6 have also low EA content and the rest of the genotypes namely, RSPN-29, DGS-1, RSPN-25, CNH-11-7, CNH-11-13, RL-1359, HNS-1101, GSC-101, CNH-11-2, HNS-1102 have high erucic content. In fatty acids (FA) content, significant differences were observed in rapeseed-mustard. Desirable cultivars with higher yield and oil content are the chief objective of this concerned study to be further employed in the breeding program.

Rising temperature has adversely affected wheat production globally. In this realm we studied various morpho-physiological traits governing heat tolerance using thirty bread wheat RILs developed via crossing LOK-1 x HUW- 468, LOK 1 x HUW 234 and Raj-4014 x PBN-51. Correlation studies reflected that traits like number of tillers per plant, plant height, and chlorophyll content were significantly positive correlated with grain yield per plant, on the other hand, path coefficient analysis revealed that the chlorophyll content (0.362) and tillers per plant (0.222) showed a significant positive correlation with grain yield per plant, whereas significant negative correlation for grain yield was exhibited with relative water loss (-0.392) and canopy temperature (-0.402) at genotypic level.
