Abstract:

The present investigation was carried out at Horticulture Research Station, Dr. Y. S. R Horticultural University, Venkataramannagudem, West Godavari district during kharif season, 2018.Based on D2 values, the twenty-nine hybrids of okra grouped into six clusters. Among the sixclusters, cluster III comprised the maximum number of hybrids (6) followed by cluster II (5), cluster V (5), cluster VI (5), cluster I (4) and cluster IV (4). The maximum inter cluster distance was observed between clusters I and VI (D2=65.06) followed by clusters II and VI (D2=62.51). Highest percent contribution towards divergence came from average fruit weight (17.49 %) followed by fruit yield per plant (13.30 %), fruit and shoot borer infestation on plants (12.07%), plant height (11.33%) and number of seeds per fruit (10.34%). The data on inter cluster distances suggested that selection of one or two elite genotypes from divergent (I & VI) and (II & VI) clusters based on the above characters and crossing them would result in more heterotic and novel hybrids in okra.
