Abstract

The general combining ability of four parents and specific combing ability of six direct crosses were estimated through combining ability analysis for yield and eleven other related traits in okra using a half diallel analysis. The ratio of gea to sca suggested the preponderance of non-additive gene action for inheritance of all the characters. The significant sca of the crosses were due to combinations of high x high, high x low, low x low gea of parents for individual fruit weight, plant height at final harvest, number of branches per plant and yield/ plant indicating additive x additive, additive x dominant and dominant x dominant types of interactions. The parent Varsha Uphar 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.
