The present study is aimed to estimate general combining ability of the parents and specific combining ability of hybrids for seed cotton yield and component traits. Combining ability analysis for seven characters was studied using diallel mating design involving 9 genotypes of cotton (Gossypium hirsutum L.). Combining ability analysis of variance revealed that non-additive gene action were important in the inheritance of various traits as evident from the significant of characters under study. Among the parents, GN.Cot-22, GJHV-337 and EC-10786 were the best general combiner for most of the characters under study. Six best combinations viz.,GJHV-337 x GN.Cot-22, GJHV-337 x EC-10786, GN.Cot-22 x KH-119, GN.Cot-22 x EC-10786, DELTA-15 x EC-10786 and GSHV-97/13 x GJHV-337 had high per se performance coupled with significant high sca can be exploited for hybrid vigour or to be utilized for the improvement of genotype.
