The present investigation comprised 30 genotypes of black gram to assess the genetic divergence based on 13 traits including seed yield. Based on Non-Hierarchical Euclidean cluster analysis, these genotypes were grouped into six clusters. Ten genotypes falls in Cluster III, forming the largest cluster followed by cluster I comprised seven genotypes, cluster VI comprised six genotypes and cluster II comprised four genotypes. Among these six clusters, cluster VI was noted as mono genotypic cluster. The maximum inter-cluster distance was observed between cluster II and cluster VI, where as the maximum intra-cluster distance was observed in cluster V. Cluster VI showed maximum cluster mean value for seed yield per plant. Therefore, Superior genotypes may be developed by hybridization between genotypes belonging to different clusters. Genotype IC-250188 showed more diverse than others because it fall in cluster VI, clustering by Ward and Tocher methods. Among all the characters, biological yield/plant (27.64%) contributes maximum followed by seed yield/plant (14.94%) and seeds/pod (12.64%).
