A field experiment organised in three different years (2021, 222, 2023) at Research and Development Station for Agriculture (RDSA) Turda studied the yield stability and seed quality of some soybean genotypes of European and Asian origin, cultivated in the conventional system. The 119 soybean genotypes were sown in the experimental field of the Soybean Breeding Laboratory and consisted of seven different maturity groups (MG), from 0000 MG to III MG, characterised by different growing season. Based on the experimental results, genotypes that originated in Europe performed better in terms of grain yield compared to Asian genetics. In years with high temperatures and water deficit during the growing season, such as 2022, it seems that better results were obtained in genotypes with purple flower compared to those with white flower; with grey pubescence compared to the brown one, and in terms of growing season, the extremes of the experiment, namely extra and very early soybean genotypes along with late and very late genotypes, overcame critical phases characterized by lack of water and high temperatures, achieving superior yields.
