A 4-parent complete diallel cross, including CRIS-134, Marvi, N-74-666/108 and DPL-14 of Gossypium hirsutum L. of diverse origin, was used for assessing the magnitude of gene action for four important traits viz. number of sympodial branches per plant, number of bolls per plant, seed cotton yield per plant, and micronaire value. All the traits were conditioned by additive and non-additive type of gene action except micronaire value which was governed by additive genes only. The parental lines CRIS-134 and Marvi proved good general combiners more or less for all the characters studied. The hybrid CRIS-134 x N-74-666/108 and Marvi x DPL-14 proved best specific combiner for number of bolls per plant, seed cotton yield per plant and micronaire value. The meaningful reciprocal effects were manifested by N-74-666/108 for almost all the traits which suggest that female parent N-74-666/108 might be used as seed parent in further hybridization programme.
