Merrill] meal and oil exporter in the world, with crops covering a 23 to 39 S latitude range, allowing the presence of genotypes from different maturity groups (MG). Multi-environment yield trials (MET) for commercial cultivars are conducted each year across the crop area. The aim of this paper was to evaluate the consistency of MG effects and its interaction with environments (E), first to investigate if different mega-environments (ME) for oil, protein, and oil+protein exist in Argentina, and second to identify superior MG regarding these
