Soybean cultivation in Europe has a great potential, however, little is known about different growing areas and no harmonized maturity group (MG) classification exists. The aim of our study was therefore to characterize different growing areas and to identify mega-environments in Europe, to characterize the MGs grown in Europe and in addition, to identify allelic variation at the maturity loci E1, E2, E3 and E4 and assess their effects on adaptation. The study comprised 22 locations across 10 countries and 75 European cultivars from five early maturity MGs (000 - II). Our results allowed the first unified assessment of soybean growing regions in Europe and illustrate the strong effect of photoperiod on soybean adaptation and mega-environment classification, as well as the effects of the E maturity loci for soybean adaptation in Europe.
