Abstract: Studies were conducted on eighteen genotypes of black gram (Vigna mungo) to evaluate their comparative performance under rainfed conditions. Highly significant differences were observed for all the traits except leaf area which showed non-significant differences. Leaf area, pods plant-1, plant height and biological yield plant-1 showed high genotypic and phenotypic variances exhibiting greater variability in these traits. The magnitude of heritability was high for 100-seed weight (94%), pods plant-1 (91%), pod length (91%), biological yield (87%), grain yield (85%), days to maturity (80%), harvest index (76%), branches plant-1 (75%) and plant height (71%) indicating additive type of gene action. Pods plant-1, branches plant-1 and biological yield plant-1 showed highly significant and positive correlation with grain yield showing that these traits have good positive effect on grain yield. Selection of genotypes on the basis of these traits can be useful. The present study enabled to identify early to medium duration lines without losing grain weight and yield potential.
