Abstract Mahalanobis D-square (D2) statistics was applied to assess diversity in the 9 gree gram genotypes from Odisha condition. These genotypes were grouped into five clusters. Cluster I and II had two genotypes each while cluster III had maximum divergence with three genotypes. Cluster IV and each shared single genotype. The inter cluster distances were greater than intra cluster distance revealing that considerable amount of genetic diversity existed among the accession. The maximum and minimum divergence was revealed between cluster V with I and cluster V with II respectively. Cluster IV and V exhibited high and low mean values respectively for most of characters. Chlorophyll content, number of pods/plant, number of seed/pod, seed weight, nitrogen content and protein content of the seed were major traits causing genetic divergence among accessions. It has been suggested that for varietal improvement hybridization among the genotypes of divergent cluster should be done in order to obtain better results in terms of variability and diversity.
