Genetic diversity analysis is a powerful tool in quantifying the degree of divergence between biological populations and to assess the relative contribution of different components of total divergence. The present investigation aimed to study the genetic divergence and clustering pattern of 50 genotypes of Green gram (Vigna radiata L. Wilczek) for selection of suitable parents that can be utilized in hybridization programme and to study the genetic parameters attributing to yield. The crosses of genotypes from cluster I, i.e. Kopergaon, Vaibhav, BM-4 and BM-2005-1 with those of genotypes BM-2003-2, PM-203- 18, AKM-9907 and AKM-08-01 belonging to cluster III and RVSM-11, PM-201-19, ML-1354, AKM-0603 belonging to cluster II has the highest intercluster distance and might produce high level of segregating population in regards to yield as well as earliness. Among the thirteen characters the protein content contributed maximum amount towards divergence. High heritability estimates coupled with high genetic advance was observed for harvest index and biological yield per plant resembling the action of additive genes in controlling these particular characters and selection would be rewarding for yield improvement.
