Initial evaluation of in breds for general combining ability (gca) enables plant breeders to discard undesirable ones and identify those that are potential for the production of superior hybrids. In this context, 11 parental in breds which are contrasting for Late Wilt Disease (LWD) reaction (4 LWD resistant and 7 LWD susceptible) and yielding ability were selected and were evaluated for their gca related to grain yield plant-1, its attributing traits and reaction to LWD infection. The analysis of variance revealed significant differences among the inbred lines for their per se performance as well as their gca. Similarly, the hybrids differed significantly for per se performance and their specific combining ability (sca) effects for all the traits. The non-significant correlation between per se performance and gca effects suggested that per se performance of inbred lines is not a good indicator of their gca effects for any of the traits studied including reaction to LWD infection. However, significant positive and fairly high magnitude of correlation between per se performance of hybrids and sum of parental gca effects for all the traits under study including reaction to LWD infection indicating that parental gca effect is good indicator of per se performance of hybrids. hence, parents having higher gca effects are expected to give good performing hybrids.
