Abstract
Genetic divergence using D2 statistic of forty genotypes of various agro-climatic region for ten
quantitative characters revealed existence of considerable genetic diversity in the material. The genotypes were
grouped into eleven clusters. Cluster VIII contained the highest number of nine genotypes followed by cluster V with
seven genotypes. The pattern of distribution of genotypes from different geographical location into eleven clusters
were random, demonstrating that geographical isolation may not be the only factor causing genetic diversity. The
highest intra-cluster distance was observed for cluster VI (112.02) and the lowest was observed for cluster II (6.24).
While the highest inter-cluster distance was observed between cluster III and X (493.41). Harvest index contributed
maximum to diversity. Cluster IX with WGG-66 recorded the highest mean for yield contributing characters viz.,
plant height, branches/plant, pods/plant and clusters/plant. Therefore it was suggested that more emphasis should be
given this genotype as parents for crossing with genotypes of other clusters which may produce novel recombinants
with desirable traits.
