General combining ability (GCA) describes the general usefulness of the parental form in terms of the concerned trait, whereas specific combining ability (SCA) indicates importance of the joint action of the genes of parental forms. Such information is useful to identify the best combiners which may be hybridized to build up favourable genes. This present investigation aimed to determine the GCA and SCA effects of...
