Abstract: A field experiment was conducted to examine the genetic divergence using Mahalanobis D2 statistics among one hundred urdbean genotypes. Significant genotypic differences were observed for twelve characters studied indicating the considerable amount of variation among the genotypes. Cluster II consisted maximum number of accessions (21) followed by cluster I and III (17) and cluster VII, X and XI consisted one accession only. The inter cluster distances were greater than intra cluster distances revealing that considerable amount if genetic diversity existed among the accessions. Higher cluster mean values for plant height, number of branches per plant, number of clusters per plant, number of pods per plant, number of days to maturity and seed yield per plant was observed in cluster VII indicating the usefulness of the genotypes present in this cluster. The genotype P 1070 may serve as potential parent for hybridization programme in the improvement of yield.
