The general combining ability of four parents and specific combing ability of six direct crosses were estimated through combiningability analysis for yield and eleven other related traits in okra using a half diallel analysis. The ratio of gca to sca suggested the preponderance of non-additive gene action for inheritance of all the characters. The signifficant sca of the crosses were due to combinations of high x high, high x low, lowx low gca of parents for individual fruit weight, plant height at final harvest, number of branches per plant and yield/ plnat indicating additive x additive, additive x dominant and dominant x dominant types of interactions. The parent VarshaUphar was adjudged as best general combiner and the hybrids MF-3 x Varsha Upphar, MF-3 x Anamika and Varsha Uphar X Arka Anamika were adjudged as the best specific combiners.
