Assessment of combining ability for fruit yield and its related traits in brinjal

Abstract

The investigation on combining ability for yield and yield-related traits in brinjal revealed that dominance variance was higher than additive variance for the majority of characters indicating a preponderance of non-additive gene action. Thus these characters could be improved through recurrent selection or heterosis breeding. The parent Mattigulla and Melavanki identified as good general combiners for various characters studied. Similarly, the cross Melavanki× Malapur and Coorg × Mattigulla identified as good specific combiners. GCA to SCA ratio was less than for many of the traits one indicating the predominance of non-additive gene action which can improve through recurrent selection or heterosis breeding.
