摘　　要：运用AMMI模型对1997～1999年甘肃省陇东片冬小麦区域试验结果进行分析,结果表明:陇原961、西峰27号、庆农8号属于高产稳产型品种;陇鉴223属于低产稳产品种;8821-45-58、9038-1、陇鉴215属于低产不稳产型品种;陇原935高产但不稳产,具有较强的区域性。从AMMI互作效应值可看出:庆农8号、陇原961、陇鉴223三个品种具有广泛的适应性;西峰27号除在通渭县外具有较广泛的适应性;陇原935对除静宁县、通渭县两个相对低产区域外,在正宁、镇原、西峰、宁县等地具有较强的适应性;88(3)-8-5-1、8821-45-58对通渭县、静宁县具有特殊的适应性。The data of winter wheat regional trial in Eastern Gansu Province in 1997 - 1999 was analyzed through the AMMI model. The results showed Longyuan 961, Xifeng 27 and Qingnong 8 had higher and more stable yield. Longjian 223 had lower but not stable yield. 8821 -45 -58, 9038 -1 and Longjian 215 had lower and not stable yield. Longyuan 935 had higher but not stable yield, it had higher regional character. From the AMMI interaction value, it can be learned that （ 1 ） Qingnong 8, Longyuan 961 and Longjian 223 had extensively adaptability ; （ 2 ） Xifeng 27 had extensively adaptability except in Tongwei County, Longyuan 935 had stronger adaptability in Zhengning, Zhenyuan, Xifeng and Ningxian Counties, but it had lower yield in Jingning and Tongwei Counties; （3）88 （3）-8 -5 - 1,8821 -45 -58 had special adaptability in Tongwei and Jingning Counties.
