摘要

Eight genetically diverse genotypes of desi cotton (Gossypium arboreum and G. herbaceum) were assessed for combining ability of 11 economic characters using diallel crossing system. The estimates of general combining ability variances indicated that both additive and non additive gene actions were involved in the expression of seven characters, while for number of nonopodia/plant and staple length of fibre only additive type gene action was involved. The parents AKA-8808, JLA-1693 and AKA-8401 were the good combiners. The crosses JLA-0193 x AKA-8808, JLA-1693 x JLA-0193, JLA-1693 x JLA-0393 and AKA-8808 x PA-141 were identified with good specific combiners for seed cotton yield and yield contributing characters.
