ABSTRACT
55 genotypes collected from various sources were grouped into seven clusters following Mahalanobis’ D2 statistics. Cluster I was the largest (34 genotypes) followed by clusters IV (eight), II (Six), V (four) and three monogenotypic clusters (III, VI and VII). The maximum intra-cluster distance was observed in cluster I suggesting that genotypes are having diverse genetic architecture. The inter-cluster distance was high between clusters II and VI there by indicating wide range of variation among the clusters. The per cent contribution towards genetic diversity was high in number of pods per plant (26.12%). Based on cluster mean and per se performance, seven genotypes were selected for hybridization.
