摘　　要：利用AMMI模型,分析了辽宁省25个水稻品种的蛋白质(PC)和直链淀粉含量(AC)的稳定性,并对G×E互作与气候因子的关系及各品种的气候生态适应性进行了探讨。结果表明,PC和AC稳定性高的品种分别有V3(辽粳294)、V15(沈农9810)、V11(0157)等和品种V2(辽农49)、V13(沈农693)、V1(仙S38)等。温度和日照是影响G×E互作的主要气候因子,PC的气候适应性表明,品种V12(花粳49)和V9(沈农9819)对相对低温和寡照的环境有特殊适应性。各品种AC的气候适应性表明,品种V20(兴3号)、V21(东亚03-51)和V6(茂洋1号)分别对低温寡照、低温多日照和高温多日照的环境具有特殊适应性。Based on AMMI model, the stability in protein and amylose contents of 25 rice cultivars in Liaoning Province was analyzed, with the relationships between genotype-environment （G × E） interaction and climate factors as well as the eco-climatic adaptability of the rice cultivars discussed. The results showed that the cultivars V3 （Liaojing 294）, V15 （Shennong 9810） and V11 （0157） had higher stability in protein content, while V2 （Liaonong 49）, V13 （Shennong 693 ） and V1 （ Xian S38 ） had higher stability in amylose content. Temperature and sunlight were the main climatic factors affecting G x E interaction. For protein content, V12 （ Huajing 49） and V9 （Shennong 9819 ） performed significant adaptability to relatively low temperature and scant sunlight ; while for amylose content, V20 （ Xing 3 ）, V21 （ Dongya 03-51 ） and V6 （ Maoyang 1 ） had specific adaptability to low temperature and scant sunlight, low temperature and more sunlight, and high temperature and more sunlight, respectively.
