In the present study, 66 urdbean genotypes were evaluated for various agro-morphological traits during rainy season (kharif)
2012 at IIPR, Kanpur to assess the level of genetic diversity among the genotypes. Based on hierarchical average linkage
clustering method and D2 statistic the genotypes were grouped into seven clusters having significant inter-cluster distances.
Shannon-Weaver’s diversity index (H) and Simpson’s index (1/D) was used to assess the phenotypic diversity for all eight
yield attributes. The H index revealed moderate diversity for most of the traits. The average Shannon – Weaver’s diversity
index for all traits in whole population was 0.54 with the lowest value of 0.49 for biological yield per plant to highest value for
grain yield per plant and pods per plant (0.58). The simple correlation coefficients showed significant positive correlation
of grain yield per plant with plant height (0.44 * * ), clusters per plant (0.65 * * ), pods per plant (0.77 * * ) and biological yield per
plant (0.70 * * ). Based on the inter cluster D2 value, genotypes with high inter cluster distances could be used in hybridization
programme to generate diversity in breeding programme.
