Abstract

In a diallel set involving 7 strains/varieties of Asiatic cotton, additive gene action was predominant for seed cotton yield. The cross Bhav-38 x 824 showed significant heterosis for yield over midparent as well as better parent, while crosses 733 x G.27 and 588 BK x G. 27 showed a significantly high heterosis for this trait over the standard hybrid check. Two parents, i.e. 824 and G.27, proved to be the best general combiners for yield. The gca effects of the parents and sca effects of the crosses were not related with their per se performance.
