The prediction of the genetic potential of crosses for generating inbred lines scoring either above or below given standards can be obtained from the F3 means and the variances among the F3 families. The methodology was tested for two soybean (Glycine max L. Merrill) traits: a) plant height at maturity, of moderate to high heritability and b) grain yield, of low heribatility. The predicitons were helpful for screening among crosses regardless of the inheritance of the trait in the absence of genotype x environmental (g x e) effects. In the presence of g x e, the use of two standards and of data from two environments improved the yield predictions. |
