Combining ability effects were estimated for different characters in a line x tester crossing programme comparing 45 crosses and 45 F2S produced by crossing 15 lines and 3 testers of okra. Parents hybrids/crosses differed significantly for gca arjd sea effects, respectively. High average degree of dominance revealed predominance of non-additive gene effects for all the traits. The parents namely KS-442, 7109, K-Bonia, KS-423, KS-437, 7216, PK, and AB-2 were found good general combiner for many of the traits. Therefore, these lines can be used for hybridization for producing promising recombinants. This indicates that parent showing high gca for edible fruit yield per plant might be due to days to flowering, plant height, number of branches per plant, number of fruits per plant. High sea effects were expressed for cross combinations, KS-305 (Red) x PK, KS-341 x AB-2, K-Bonia x AB-2, KS-423 x BO-2, AB-1 x AB-2 for fruit yield per plant and also exhibited high sea effects for edible fruit yield component traits.
