ABSTRACT

Mode of gene action and heritability were estimated for ginning out-turn, staple length, fibre maturity, fibre fineness, fibre strength and yield of cotton. Six genotypes B-557, Culture 728-4, MNH156, B-1850 (ne), Culture-604-4 and MNH147 were crossed in all possible combinations in diallel fashion. The results from scaling tests for the adequacy of additive-dominance model indicated that ginning out-turn, fibre fineness and fibre strength were found full adequate, whereas staple length, fibre maturity and seed cotton yield were partially adequate for further genetic analysis. Ginning out-turn, fibre fineness, fibre strength and yield were controlled by additive genes, whereas over-dominance was prevalent in staple length and fibre maturity. High narrow sense heritability for ginning out-turn and fibre strength suggested that these parameters could effectively be improved through selection in the early segregating generations, whereas chances of improvement for fibre fineness and seed cotton yield would be moderate as heritability estimates for these parameters were medium (h2 NS = 0.608 and 0.702%, respectively but poor for staple length.
