摘要

Western Himalayas is a hot spot for common bean variability. We evaluated 45 diverse genotypes for ten agronomic and seven seed nutritional traits, as well as disease response and molecular diversity analysis using 50 SSR markers. Significant variability was recorded for all the agronomic and seed micronutrient traits as revealed by higher mean, broader range and higher CV values. Among nutritional traits, iron content was as high as 114.00 ppm, whereas zinc content as high as 57.00 ppm. Seed yield per plant showed significant positive correlation with pods per plant and seeds per pod. In case of seed nutritional traits, iron was positively correlated with Mn, K and Zn. However, most of the yield traits did not show any significant correlation with nutritional traits except seed length and breadth. GY*T approach elucidated the trait relationships in a more objective manner and identified superior genotypes for agronomic and nutritional traits. Genotypes WB-54, WB-954, WB-451, WB-185, and WB-352 showed higher positive MSI values indicating higher overall superiority for agronomic and seed nutritional traits. Several genotypes exhibited stable resistance to ALS, ANT and BCMV with WB-396, WB-1607, DARS-10, PBG-26 and N-7 showing resistance to more than one disease. SSRs were highly effective in discriminating bean genotypes with PIC value ranging from 0.496 to 0.857. Population structure revealed three groups with group-II having largest number of genotypes. In the present study identified several genotypes that could be used for improving agronomic traits, seed micronutrients as well as disease resistance for sustainable bean farming systems in Kashmir valley.
