A 5x5 diallel analysis was conducted to study the inheritance of seed cotton yield, number of bolls and boll weight in Gossypium hirsutum L. using combining ability technique. The analysis of the data revealed that variance due to specific combining ability was significant for all the three traits signifying the importance of non additive gene action. The comparison of the parents showed that NF-801-2-37 was the best general combiner for seed cotton yield, number of bolls and boll weight followed by Acala-63-75. Best hybrid combinations identified were Acala-63-75 x NF-801-2-37 for seed cotton yield and DPL-61 x NF-801-2-37 for number of bolls and boll weight. Higher proportion of dominance variance in all three traits suggested delayed selection or use of heterosis breeding in crop improvement programs.
