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.  aBrazil  abreeding  ainbred lines  aCruzamento  aGlycine Max  aMelhoramento  aSoja  aBrasil  aCross  aGenetic potential  aLinhas puras  aParana  aPotencial genetico  aSoybean1 aTOLEDO, J.
