To evaluate the genetic control associated with certain fiber properties when High Plains and Acala cultivars are hybridized, a factorial mating design was used to cross randomly‐ selected High Plains and Acala lines. The hybrid populations that resulted from those crosses were used to obtain estimates of genetic variances for fiber length, strength, elongation, and fineness. Additive genetic variance predominated for fiber length, strength, and elongation. Most of the phenotypic variance for fiber fineness was due to the environmental component; however, a statistically significant, nonadditive component was observed. The results suggested that in general, within segregating populations derived by hybridizing High Plains and Acala cultivars, lines can be selected that have desirable combinations of fiber length, strength, and elongation, but that genetic gain for fiber fineness will probably be difficult.Read More
