Thirty five genotypes of mung bean were evaluated during kharif 2011 with the objective to work out the genetic divergence in the genotypes for future breeding studies. Significant differences were observed for all the traits studied. The material was subjected to genetic analysis and further, based on Mahalanobis D2 statistics genotypes were grouped into seven clusters, with cluster II having maximum of 13 genotypes, cluster-I 11 genotypes and cluster IV and V, (4 genotypes each) and the rest of the cluster were monogenotypic. Inter-cluster distance was maximum between cluster VI and VII (9308.29) followed by cluster IV and VII and Cluster I and VII (5236.69) the cluster means for seed yield plant-1 revealed that the magnitude of differences among the means ranged from (4.65 g) in cluster IV to (2.83 g) in cluster V. On the basis of divergence between clusters, genotypes from cluster-VI and VII followed by cluster-IV and VII can be involved in the hybridization program for recovery of superior recombinants or transgressive segregants in segregating generations.
