摘　　要：为筛选云南省不同生态区、不同栽培水平条件下的优良新品种,为该区域玉米新品种精准推广和培育提供参考依据。本研究以9个玉米品种(系)在云南省15个试点的区域试验籽粒产量数据为研究对象,通过AMMI模型和GGE双标图分析方法分析不同玉米品种(系)在云南省不同试点的丰产性、稳定性和适应性,同时综合评价参试地点的鉴别力和代表性。结果表明:基因型效应、环境效应以及基因型与环境的互作效应均对参试品种产量产生极显著影响;综合产量、AMMI模型分析及GGE双标图结果,G3(文17-115)、G6(文15-5851)和G5(文17-5313)属较理想品种;E15(普文镇试验点)和E2(石林县试验点)是综合性较好的试点,均具有较强的区分力和代表性。AMMI模型和GGE双标图分析的侧重点不同,但品种评价结果基本一致,两种方法优势互补,可以用来作为全面有效地评估品种和试点的理想工具。The study aims to screen new maize varieties with high quality in different ecological regions and under different cultivation conditions in Yunnan Province.Based on the grain yield data of 9 tested maize varieties in 15 test sites in Yunnan,the high yield potential,yield stability and variety adaptability of the tested maize varieties were analyzed by AMMI model and GGE biplot analysis method,and the discriminability and representativeness of the test sites were comprehensively evaluated.The results showed that the effects of genotype,environment and the genotype and environment interaction on maize yield were extremely significant.Comprehensive yield,AMMI model analysis and GGE biplot results showed that G3(Wen 17-115),G6(Wen 15-5851)and G5(Wen 17-5313)were ideal varieties,and E15(Puwen town site)and E2(Shilin site)were well-integrated test sites,which had relatively strong discriminability and representativeness.AMMI model and GGE biplot analysis had different analysis emphases,but the evaluation results of the varieties were similar.The two methods could be complementary to each other and taken as the ideal tools for comprehensive and effective evaluation of varieties and test sites.
