Assessment of genetic diversity in okra [Abelmoschus esculentus (L.) Moench]

The present investigation was carried out at Horticulture Research Station, Dr. Y. S. R Horticultural University, Venkataramannagudem, West Godavari district during kharif season, 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 =) followed by clusters II and VI (D2 =). Highest percent contribution towards divergence came from average fruit weight ( %) followed by fruit yield per plant ( %), fruit and shoot borer infestation on plants (), plant height () and number of seeds per fruit (). 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. | Assessment of genetic diversity in okra [Abelmoschus esculentus (L.)
