Abstract


Knowledge on the prepotency in the parents of the hybrid is an essential requirement. To have the information on combining ability of the parents and crosses, a set of eighty one cross combinations of nine male sterile lines and nine restorer lines of sorghum were studied. Analysis of variances showed significant differences among the genotypes for days to 50 per cent flowering and grain yield per plant. The variance due to lines was significant and larger in magnitude. Days to 50 per cent flowering is largely under control of non-additive genetic effects. The components of variance for grain yield due to GCA and SCA pointed out the preponderance of non- additive gene action as reflected by high SCA variance. The male steriles 296A, 2077A and TNAU ms 1A among the lines and Co 25, TNS 34 and IL 101 among the testers with more of additive genetic effects could be utilized in exploitation of hybrid vigour
