Abstract: Thirty three hybrids were developed by crossing seven lines and three testers in L x T fashion at Division at Biotechnology and crop improvement, COH, Bagalkot during 2016-17 and assessed for their character association, path analysis heterosis and combining ability for twenty six parameters for productivity and quality traits. The variance due to parents vs. hybrids was also significant for all traits except plant height at 45 DAS, internodal length 45 DAS, days to first flowering, fruit diameter and seed yield per plant. The magnitude of standard heterosis was high and significant for marketable yield per plot in the cross L4 x T2 (30.36%) followed by L1 x T2 (28.44%), L3 x T2 (24.19%) and L1 x T1 (12%). Comprehensive assessment of parents by considering gca effects of 26 characters studied has resulted into identification of lines, viz., L7, L3, and L1 and the testers T2 and T3 as good combiner over all characters and among the hybrids L3 x T2, L7 X T2, L3 x T3, L1 x T3 and L7 x T2 showed good specific combiner for almost characters which can be used as high yielding hybrids. Non additive component of genetic variance was slightly higher than additive component for all the traits they can be subjected to recurrent selection for improving the combining ability for exploitation of heterosis. The study on correlation found that total fruit per plant had positive and highly significant correlation with plant height, first flowering node, number of nodes per plant, number of fruits per plant, average fruit weight. From path analysis it became clear that plant height at 90 DAS, days to first harvest, number of nodes per plant, number of fruits per plant, average fruit weight, exerted direct positive effect towards fruit yield per plant. Thus selection could be made relying on average fruit weight and number of fruits per plant for high yielding types. The information presented here about quality traits of okra showed the potential nutritional importance of okra and it has role in improved nutrition.
