Abstract

                                A study was conducted in mungbean (Vigna radiata (L.) Wilczek) to assess the combining ability of the parents as well as hybrids involving five lines and four testers crossed in line x tester model. The ratio of additive and dominance genetic variance (σA2: σD2) indicated that all the characters were found to be predominantly controlled by non additive gene action except solids lost which is governed by both additive and non additive gene action. The parents Vamban 2 and VGG 77 were found to be good general combiners for most of the quality traits and yield. The crosses ML 682 x Vamban 2, VGG 77 x KM 2 and VGG 80 x KM2 were identified as best specific combiners.

Key words : combining ability, additive genetic variance, dominance genetic variance, quality.
