| Abstract: | Five fiber traits of 8 parents and their 28 F 1 crosses of upland cotton were analyzed for their additive dominance and maternal effects alternatively by MINQUE(1) approaches. The results indicated that maternal effects for 2.5% span length, uniformity and elongation were statistically signsificance at 0.10, 0.05 levels.Fiber strength and micronaire value didn't show maternal effects. The fiber traits were mainly controlled by the additive effects and by dominant effect rather significantly as well. Broad and narrow sense heritability estimates were significance at 0.01 level for fiber traits. The better parent beterosis of fiber traits were analyzed by the genetic model of additive dominance by MINQUE(1) approaches for predicting the genotypic value and heterosis for offspring of hybrids. The fiber traits were significantly negative for the better parental heterosis in upland cotton. |
