Abstract


Three Indian okra (Abelmoschus esculentus) varieties, along with 7 exotic lines, were involved in making a diallel set of crosses. The parents and their 45 F< sub>1</ sub> progeny were evaluated for weight of good pods (without borer infestation) per plant. Crosses between India and exotic varieties gave the highest yields of good pods, with the best combinations being IHR x PI489782 (from the Ivory coast), Pusa Sawani x Smooth Green (from the Philippines) and Pusa Sawani x PI496620 (from Ghana) (500, 325.5 and 305.8 g, respectively). PI489782 registered the highest GCA for pod yield and was also the best general combiner based on pooled score analysis of GCA for 9 other qualitative traits.
