| ABSTRACT Ten crosses of peanut resulted from half diallel and five peanut were employed to estimate combining ability. General and specific combining ability, were highly significant for most studied traits. Additive and non additive were the prevailed type in the genetics of the studied traits. Three crosses i.e, P1×P2, P1× P4 andP4×P5had positive and significant specific combining ability (SCA) for most of yield and yield components. Additive genetic variance (D) and dominance genetic one (H1 and H2) were highly significant for most of yield and yield components. Average degree of dominance was more than unity and heritability in narrow sense was high for pod weight/pl., 100-pod weight and 100-seed weight (59%, 61%, 83%) respectively. | ||||
