Abstract: 30 genotypes of clusterbean were studied for genetic divergence analysis utilizing Mahalanobis D2 technique. Genetic divergence analysis revealed that genotypes could be grouped into 6 clusters. The cluster I was the largest and consisted of 16 genotypes followed by cluster II with 10 genotypes and cluster III, IV, V and VI had solitary genotype. Therefore, selection and intercrossing of genotypes involved in these clusters would be useful for inducing variability in the respective characters. Average intra and inter-cluster D2 values among 30 genotypes revealed that cluster I recorded maximum intra cluster distance followed by cluster II revealing thereby the existence of diverse genotypes in these clusters. While, inter cluster differences were maximum between cluster II and cluster IV followed by II and V, IV and VI, I and VI and I and III indicating that the genotypes from these clusters can be selected for future breeding programme to produce heterotic hybrids.
