Rye (Secale cereale L.), as an important crop with both food and feed value, has strong adaptability in arid and semi-arid regions and is a key variety resource for ensuring food security and the development of animal husbandry. However, under dryland conditions, the yield and quality of rye are highly constrained by environmental factors, showing a significant genotype-environment interaction (G×E) effect. To deeply assess the performance of superior rye varieties in different ecological regions, this study, based on the multi-environment test (MET) method, systematically analyzed the yield, quality, stress resistance and resource utilization efficiency of multiple elite rye varieties under typical arid conditions. By comparing the yield differences, stability of quality traits and water and nitrogen utilization efficiency under different ecological environments, Combining GGE-Biplot and stability analysis methods, varieties with high yield, high quality and wide adaptability were screened out. The research results show that multi-environment trials can not only reveal the restrictive factors of the environment on rye production, but also provide a theoretical basis for regionalized variety recommendation and the establishment of breeding goals in dryland farming areas. This study aims to promote the application and popularization of superior varieties by scientifically evaluating the comprehensive performance of elite rye varieties under dryland conditions, and to provide references for future rye breeding and sustainable agricultural development in arid areas.
