Abstract
In kharif 2024, the current study was carried out using a Randomised Block Design with three replications at the School of Agriculture, Loyola Academy Degree & P.G College. The goal of the current study was to analyse 40 Blackgram genotypes and one check (T-9). 40 Blackgram genotypes were found to differ significantly across all 13 quantitative characters examined by analysis of variance. For biological yield/plant, plant height, and harvest index, the most genotypic and phenotypic diversity was noted. For the number of branches/plant, biological yield/plant, and seed yield/plant, the highest GCV and PCV were noted. Biological yield/plant, days to maturity, seed/pod, number of branches/plant, and seed yield/plant all showed high heritability. For biological yield/plant, strong heritability and high genetic advancement as a proportion of the mean were noted.
