Accurate identification and evaluation of germplasm can enhance its effective use. To evaluate the environmental adaptability and stability of Chinese soybean germplasm, we applied the additive main effects and multiplicative interaction (AMMI) model to analyze the two years' data of the 60 mini core collections of soybean in three provinces in the Huang-Huai region. The results showed that the interactions between the genotypes and environment (G×E) for plant height, effective branch number, 100-seed weight, and yield per unit area were highly significant (P＜0.01), and the squares of G×E to total squares were 16.73-24.57％, suggesting a need of further analysis for the stability of varieties. The phenotypes of different varieties were dependent on the planting sites, and some germplasm performed wide adaptability while others not in particular environment. The results laid a theoretical foundation to effectively use mini core collection for soybean breeding in Huang-Huai region.
