Abstract
Forty-eight okra accessions were subjected to a replicated field trial arranged in a Randomized Complete Block Design (RCBD) to examine the genetic dissimilarity and distances pertaining to quantitative traits. Mahanalobis D2 analysis portioned the genotypes into ten separate clusters. Cluster II constituted the largest group followed by cluster III. Also three solitary clusters (VII, IX, and X) were reported. In compliance with genetic distances, cluster IV, VIII and VI had broad divergent genotypes within them along with wide genetic dissimilarity was between the clusters VII and X, following I and X, I and IX. Cluster IX had genotypes with high cluster means for fruit yield than others. Among various morphological characters, fruit yield per plant alone contribute nearly 36 per cent toward divergence preceded by days to first flower, and plant height at 80 per cent maturity. Therefore, top priority in artificial selection of diverse parents might be given to the genotypes in clusters I, II, VII and IX for attempting improvement of complex traits in okra.
