ABSTRACT
Fourty four okra genotypes were assessed for genetic divergence using Mahanalobis D2
statistics. The population was grouped in to
twelve clusters. The cluster III was the largest with eight genotypes followed by cluster I and VIII with seven, cluster II with five, cluster
XII with three while, clusters IV, V, VI, IX, X and XI included only two genotype in each. The clustering pattern indicated that there was
no association between geographical distribution of genotypes and genetic divergence. The intra-cluster distance was maximum in
cluster XII (28.14), while inter-cluster distance was maximum between cluster VI and VIII (35.57) followed by I and IX (35.31), thus
being a good source for attempting hybridization. The characters namely days to 50% flowering (35.62%), 100 seed weight (28.44%),
number of seeds per fruit (17.23%) and average fruit weight (8.14%) were directly contributed towards maximum divergence and,
therefore, selection of divergent parents based on these characters is recommended for getting good hybrids or segregants in okra.
