Abstract: 【Objective】To accurately evaluate the impacts of genotype-environment interaction effect on the yield traits stability of summer maize varieties,and to assess the statistical analysis method suitable for multi-point test of summer maize in Huang-Huai-Hai area.【Methods】Using AMMI model,the grain yield,grain weight per panicle and 100 grain weight of 15 tested summer maize varieties(control variety Zhengdan 958)in the multi-point test in Huang-Huai-Hai area in the year of 2019 were measured in 21 different pilot sites,and the genotype effect,environment effect and genotype-environment interaction effect were analyzed.【Results】The genotype effect,environment effect and genotype-environment interaction effect of grain yield,grain weight per panicle and 100 grain weight reached an extremely significant level(P<0.01). Among the tested varieties,Hengyu 7182 and Xianyu 335 had high and stable yield;Hengyu 7182,Huayu 168 and Longping 206 had high and stable grain weight per panicle;Dongke 301,Lianchuang 5 and Hengyu 7182 had higher 100 grain weight and better stability;the control variety Zhengdan 958 had good stability and common yield traits.【Conclusion】Hengyu 7182 was a high-yield and stable variety,which was more suitable for planting in summer maize area of Huang-Huai-Hai area;AMMI model could accurately and intuitively evaluate the stability of the tested varieties,and could be used as an analysis method for summer maize new variety screening in multi-point test.
