The nature and magnitude of genetic effects on morpho-yield traits were studied in a 6 × 6 F1 and F2 diallel cross in upland cotton. An additive-dominance model was adequate for most of the traits except plant height and seed cotton yield, where the model was partially adequate. Genetic parameters were estimated following Hayman�s and Mather�s model. Additive effects controlled lint percentage and monopodia in both generations, and plant height and sympodia in F2. Non-additive inheritance with over-dominance controlled yield in both generations, and plant height and sympodia in F1. Most traits presented an unequal proportion of positive (U) and negative (V) alleles in the loci (H2<H1) and an asymmetrical distribution of genes in the parents...
