摘要

Mahalanobis's D2 statistics was used to study the genetic diversity among 40 genotypes of vegetable Indian bean(Lablab purpureus L.) grown during kharif 2011-12. Observations recorded on 13 characters revealed the wide genetic diversity. By adopting Tocher's technique, the 40 genotypes were grouped into nine clusters. The average intra-cluster distance revealed that the genetic diversity among the genotypes in cluster-I (6.36) was minimum followed by cluster-VIII (6.52). The maximum intra-cluster distance was observed in the cluster-VI (7.34). Selection within this cluster might be exercised with emphasis on high mean values for the desirable traits. The relative divergence of each cluster from other clusters (inter-cluster distance) indicated high order of divergence between clusters-VII and VIII (29.23) followed by clusters-V and VII (26.06) and clusters-IV and VIII (24.78). Selection of parents from these clusters would help to achieve novel recombinations in future breeding programmes. Per se performance had maximum contribution of 61.15% by number of pods per plant followed by green pod yield per plant (15.77%) towards the divergence.
