Tobacco is one of the worldâ€™s creditable crops. This relevant study significant and desirable determine of variability due variance of specific combining ability (sca) suspend significantly for all the traits under study indicating the importance of non-additive gene action for the inheritance of these characters. As variance due to both GCA and SCA were found significant for most of the character appeared to be under the influence of both additive and non-additive gene actions. The estimates of gca effects suggested those parents, GC 1, AR 72, Motihari Hemti and Sel.15-16 were good general combiners for cured leaf yield and its related attributes. The estimates of sca effects indicated that the cross GC 1, AR 72, Motihari Hemti and Sel.15-16 were the most promising for cured leaf yield and some of its related traits. The success of any breeding programme largely depends on choice of parents and breeding procedure adopted. Persistent efforts are being made to improve yield and yield contributing characters in tobacco through hybridization.
