Abstract :
Combining ability analysis on of quantitative traits in rice bean Vigna umbellata [(Thunb.) Ohwi. Ohashi] was studied using 6 x 6 parents half dia11el cross in the FI generation. The variances due to gca (except for clusters/plant) and sca were highly significant, indicating the prevalence of additive and non-additive gene action for all the traits studied. The estimates of gca components were higher than sea components for all the traits, except clusters/plant indicating the predominance of the additive gene action for the traits. Parents RBL-50IPRR-2, RBL-6/RBL-l, were good general combinations for pods/plant and clusters/plant respectively. RBL-17/KHRP-2, RBL-6/KHRP-2 and RBL-6IPRR-2 were good specific combinations for grain yield.
