Thirty genotypes of greengram used to study the nature and magnitude of genetic divergence using Mahalanobis's D2 Statistics. The data for twelve important quantitative traits recorded from the genotypes raised in Randomized Block Design having three replications. Thirty greengram genotypes were grouped into six clusters. Cluster I was largest with eleven genotypes followed by cluster V with seven genotypes. The maximum inter-cluster distance was observed between cluster II and IV, suggesting that the genetic architecture of the genotypes in one cluster differ entirely from those included in other clusters. Three characters viz., seed index, biological yield, and plant height contributed maximum in manifestation of genetic diversity. Seed yield per plant had maximum phenotypic and genotypic Coefficient of Variation (PCV and GCV), followed by number of primary branches per plant. High magnitude of heritability (broad sense) was recorded for biological yield per plant. High heritability coupled with high genetic advance was observed for plant height and biological yield per plant suggesting that, the role of additive gene effect and possibilities of achieving high genetic progress through selection. The genotypes RMG-1014, RMG-1052, MIRCO-1008 and RMG-1078 were identified as genetically diverse parents, which can be utilized for future crop improvement programme.
