Abstract
Combining ability effects were estimated for yield, yield components and plant height in a 9 x 9 diallel analysis excluding reciprocals. The variances for general combining ability (GCA) and specific combining ability (SCA) were highly significant indicating the presence of additive as well as non-additive gene effects in the traits studied. The relative magnitude of these variances indicated that additive gene effects were more prominent for all the character under study. The eggplant genotype P4 proved to be the best general combiner for yield followed by P1 and P5. In general the cross P4 x P5 proved better for yield and also number of fruits per plant, whereas the cross P7 x P9 for fruit diameter and individual fruit weight.
