Abstract: Line × tester analysis was conducted to assess the GCA for 12 parents and the SCA for 32 hybrids of the eggplant. The combining ability investigation revealed large variations for all the characters. The variance estimates, GCA and SCA were highly significant for most of the traits emphasizing the importance of additive and non-additive gene actions in inheritance of fruit yield and its contributing traits. Among the female parents, PR-5 and PLR-1, whereas, among male parents, BCB-464, BCB-71-1, Swarna Mani and CO-2 were effective general combiners for fruit yield and its influencing characteristics. According to the action of the impacts of specific combining ability, the cross combinations, viz. PR-5 × BCB-71-1, PR-5 × BCB-464, PLR-1 × BCB-71-1 and PLR-1 × Swarna Mani exhibited desirable effects in all three environments (seasons) as well as over pooled environment.
