DOMINANCE AND EPISTASIS IN HETEROSIS OF WHITE LEGHORN STRAIN CROSSES

Genetic effects of aging on egg quality traits in the first laying cycle of White Leghorn strains and strain crosses.

Three White Leghorn strains, their two-way crosses, and two commercial lines were used to evaluate the effects of aging on heterosis (H), reciprocal effects, and additive (A), Z-chromosome (Z), and heterotic effects and their variances on egg quality traits during the first laying cycle. Egg weight (EW), specific gravity (SG), Haugh unit (HU), and albumen height (AH) were measured at 240, 350, ...

Dominance, overdominance and epistasis condition the heterosis in two heterotic rice hybrids.

Two recombinant inbred (RI) populations having 194 and 222 lines each, derived, respectively, from a highly heterotic inter- (IJ) and intrasubspecific (II) hybrid, were backcrossed to their respective parents. The RI and two backcross populations along with F1 and its two parents of each hybrid were evaluated for nine important traits, including grain yield and eight other yield-related traits....

Heterosis and Inbreeding Depression in Two Soybean Single Crosses

Heterosis is considered to be of little importance in soybean (Glycine max L. Merr.) because the crop is produced as “pure-line” cultivars or blends of inbred lines. The F1 generations Holladay/ Hutcheson (Cross 1) and Brim/Boggs (Cross 2) were generated by hand pollinations. Inbred generations were generated by bulk selfing. The F1, F2, F3, F4, and F5 generations were yield-tested in replicate...
