Abstract: Combining ability analysis was carried out in 36 F1’s derived out of half diallel using nine parents in Greengram. Significant differences were observed for GCA and SCA among parents and hybrids for all the traits under study. Analysis of combining ability revealed that mean squares due to general and specific combining ability were highly significant for all the characters indicating importance of both additive as well as non-additive gene effects involved in the expression of all the characters. However, higher magnitude of specific combining ability variances for almost all the traits pointed out that the preponderance of non additive component of the genetic variance was involved in the expression of the characters. For the improvement of seed yield, the crosses involving the parents, MGG-347, WGG-42, LGG-543, RM 12-13 and KM 11-564, need special consideration. The cross combination, MGG-347 X KM 11-564, was the best for high seed yield on the basis of SCA. The specific crosses, WGG-42 X RM 12-13, LGG-543 X KM 11-564 and MGG-347 X RM 12-13, revealed high number of pods coupled with high seed yield.
