AhmadManzoor 8200038Genetic analysis of F1 and F2 data obtained by crossing eight parents in diallel fashion was made following simple additive dominance model, in order to study the type of gene action controlling variation in oil content in Gossypium hirsutum L seed. The parents and 56 hybrids differed significantly from each other for oil content. Estimation of genetic components of variation showed that non additive genes controlled oil content in F1 generation and the genes with additive properties appeared to be important in F2 generation, with varying degrees of dominance in both the generations. Dominance acted towards the parents with higher oil content. Depending upon the magnitude of additive gene effects estimates of heritability in narrow sense were moderate in F1 and high in F2. The presence of additive genes effects and high estimate of heritability of oil content in F2 generation suggest that prompt and effective progress in oil content may be made following recurrent selection method.]]>Azhar, F.M. and T.
