Abstract:
Combining ability analysis was carried out for fruit yield and yield attributing traits in brinjal. Both general combining ability (GCA) and specific combining ability (SCA) variances were highly significant for almost all the characters indicating the importance of both additive and non-additive gene actions. SCA variances were higher than the GCA variances except for three characters, indicating non-additive gene action in most of the traits and these traits can be improved by heterosis breeding. These hybrids would be advantageous for production and quality improvement. The three characters like plant height, fruit length and fruit length to diameter ratio showed additive gene action which can be improved by reciprocal recurrent selection. The parents like Biliuddabadane, Natibadane and Mullukaibadane showed highly significant positive GCA effects, the crosses Thailand badane x Doddamullinabadane, Sakleshpurbadane x Doddamullinabadane and Bilichandubadane x Mullukaibadane showed the highly significant positive SCA effects for the yield per plant.
