Twenty-three diverse types of dolichos beans were evaluated for yield and their contributing characteristics. Genotypes were grouped into seven clusters on the basis of the relative magnitude of D2 values. The maximum inter-cluster distance was observed between cluster III and cluster VI followed by clusters V and VI. The minimum inter-cluster distance was observed between cluster I and cluster VII. The maximum intra-cluster distance was in cluster VI followed by cluster IV. The mean value for most of the traits was highest in cluster V. Pod yield plant-1 followed by crude fibre, crude protein and number of seeds pod-1 and green pod girth contributed higher towards genetic divergence. Hence, that the genotypes from cluster V and cluster I could be selected for crop enhancement.

Keywords : Dolichos bean, Hyacinth bean, genetic divergence, variability.
