评价西北春玉米区各品种的丰产性、适应性和稳定性以及不同地区的鉴别力和代表性，为西北春玉米区选择适宜品种提供参考。通过AMMI模型和GGE双标图线性统计模型2种分析方法，对玉米新品种ZD2008、ZD2139、ZD2141、ZD2230和对照品种先玉335 在2021—2022年开展的西北春玉米区绿色通道试验中白银市景泰县、临夏州临夏县、平凉市崆峒区、庆阳市庆城县、武威市凉州区、张掖市甘州区、银川市永宁县、中卫市中宁县、延安市黄陵县、榆林市靖边县等10个试点的试验数据进行适应性和稳定性综合分析。结果表明，试验各品种间、各试点间的差异均达到了显著水平，且参试玉米品种与试点间的互作效应也达到了显著水平，其中试验地点以张掖市甘州区的稳定性最好，参试玉米品种以ZD2141的稳定性最好。GGE双标图线性统计模型反映出玉米品种ZD2141在白银市景泰县、银川市永宁县、中卫市中宁县、延安市黄陵县、榆林市靖边县等试点的表现较好；玉米品种ZD2139在平凉市崆峒区、庆阳市庆城县、武威市凉州区、张掖市甘州区等试点的表现较好，说明这2个品种具有较广泛的适应性，建议加以推广。

This study evaluated the yield potential, adaptability, and stability of maize varieties in the Northwestern Spring Maize region, as well as the discriminative power and representativeness of different regions, providing a reference for selecting suitable varieties for this region. Using two analysis methods, i.e., the AMMI model and the GGE biplot linear statistical model, this study conducted a comprehensive analysis of the adaptability and stability in maize new varieties ZD2008, ZD2139, ZD2141, ZD2230, and the control variety Xianyu 335. The analysis was based on experimental data from 10 sites in the Northwestern Spring Maize Green Channel Experiment conducted from 2021 to 2022 with Jingtai County of Baiyin City, Linxia County of Linxia Prefecture, Kongtong District of Pingliang City, Qingcheng County of Qingyang City, Liangzhou District of Wuwei City, Ganzhou District of Zhangye City, Yongning County of Yinchuan City, Zhongning County of Zhongwei City, Huangling County of Yan'an City and Jingbian County of Yulin City included. Results showed that the differences between experimental varieties and experimantal sites were significant, and the interaction effects between the maize varieties and experimantal sites were also significant. Among the experimantal sites, Ganzhou District of Zhangye City showed the best stability, while among the maize varieties, ZD2141 demonstrated the best stability. The GGE biplot linear statistical model revealed that the maize variety ZD2141 performed well in experimantal sites such as Jingtai County of Baiyin City, Yongning County of Yinchuan City, Zhongning County of Zhongwei City, Huangling County of Yan'an City, and Jingbian County of Yulin City. The variety ZD2139 performed well in experimantal sites such as Kongtong District of Pingliang City, Qingcheng County of Qingyang City, Liangzhou District of Wuwei City, and Ganzhou District of Zhangye City, indicating that these two varieties have broad adaptability and are recommended for promotion.
