The present investigation on combining ability studies was undertaken in 10 x 10 diallel set, excluding reciprocals, for grain yield and its 14 component traits in pearl millet. Both general combining ability (GCA) and specific combining ability (SCA) variances were highly significant for all the characters in all the three environments. The predictability ratio of GCA and SCA revealed preponderance of non additive genetic components for threshing index, harvest index, starch content, earhead weight and grain yield, while, both were equally important for plant height, ear head length, 1000 grain weight and protein content. Among the parent, J-2290, J-2340, RH-RBI-458 and SB-170-06 were found to be uniformly best parent across the environments for grain yield per plant and could be used in hybridization programme to exploit their GCA effects for grain yield and attributing traits. The crosses viz., J-2444 x J-2290, J-2290 x SB-170-6, J-2444 x RH-RBI-458, J-2340 x J-2290 and J-2290 x D-23 were the most promising having good SCA, coupled with high per se performance and heterobeltiosis for grain yield and its components. Analyses of crosses revealed majority of the superior crosses were involved good x good, good x poor and poor x poor general combiners.
