Combining ability was studied in 6 x 6 diallel set (excluding reciprocals) of cowpea for pod yield and its eleven component characters. Both gca and sca variances were highly significant. The higher magnitude of gca variance compared to sca variance indicated preponderance of additive gene effects for the inheritance of all the characters studied. Parents, Chikhali Local and Kashi Kanchan were identified as good general combiners for pod yield and its contributing traits. Majority of their crosses had also manifested significant and desirable sca effects for pod yield per plant. Out of fifteen crosses, six hybrids displayed significant and desirable sca effects for pod yield per plant. Of these Chikahli Local x Pusa Phalguni, Gadchiroli 4 x GADCP 3 and Chikhali Local x Pusa Komal had exhibited high positive sca effects for the trait. An analysis of crosses revealed majority of the superior crosses were involved high x low and in few cases high x high or low x low general combiners.
