COMBINING ABILITY STUDIES IN MUNG BEAN (VIGNA RADIATA (L.) WILCZEK)

Abstract

Combining ability studies were carried out through a 5 X 5 diallel cross for seven quantitative characters. Variances due to general and specific combining ability were significant for all the characters. Additive gene effects for branches/plant and test weight and nonadditive gene effects for days to maturity, plant height, pods and seed yield/plant, and seed protein were predominant. The best combiners were McTM 11/395 for earliness, PS 11 for dwarfness, pods and seed yield/plant, EC 213012 for branches/plant and test weight, and Co2 for protein content. The cross McTM 11/395 X EC 213012 showed highly significant sca effect for earliness, dwarfness, branches and seed yield/plant, and protein content.
