Abstract: 100 greengram genotypes were evaluated to estimate genetic variability and divergence among genotypes for future breeding studies during Kharif, 2018 in RBD with three replications. Genetic analysis revealed that number of primary branches per plant showed high GCV and PCV followed by number of clusters per plant. High heritability was recorded for protein content. High heritability coupled with high genetic advance as percent of mean was observed for days to 50% flowering and number of clusters per plant. The germplasm was further subjected to Mahalanobis D² statistics and grouped into ten clusters. Cluster II was largest with 18 genotypes followed by cluster IV and VI. The maximum inter cluster distance was observed between cluster III and IV (1128.22) followed by cluster I and IV (1106.89), while minimum inter cluster distance was observed between cluster III and X (39). Cluster IV showed highest mean value for seed yield per plant.
