Effects of the G, E, and GE interaction were found to be significant and accounted for 51, 12, and 36% of the variation, respectively. The first and only significant interaction principal component axis (IPCA1) accounted for 26% of the sum of squares due to original GE interaction. This concentrated the largest proportion of the pattern of GE interaction. Environments associated with Anhembi and Esalq proved more favorable, while Areão contributed negatively to the grain yield. However, Anhembi and Areão were more predictable for the crop years. USP 93-5082 and USP 93-5243 lines combined high adaptability and stability.  aCrop yield  aGenotype-environment interaction  aSoybeans  aGlycine max  aRendimento  aSoja  aAdaptabilidade  aAdaptability  aAMMI model  aEstabilidade  aEstability  aInteração genótipo-ambiente  aInteracción genotipo-ambiente  aModelo AMMI  aRendimiento de los cultivos  aSemillas de soja1 aVELLO, N.
