摘　　要：为了确定黄淮海地区2020年夏播青贮玉米区域试验参试品种的丰产性和稳定性,为进一步的品种推广种植提供合理的分析方法和理论参考,选用2020年黄淮海夏播青贮玉米667 m^(2)5000株密度组区域试验参试的15个品种(系)、13个试点的数据,应用基因型主效应与基因型×环境相互作用(GGE)双标图的分析方法,分析参试品种的丰产性和稳产性以及试点的区分力和代表性,结果表明,丰产性和稳产性较好的品种为皖农科青贮6号、川单99、连青贮101和渝青玉9号,也是本组区域试验较理想的品种,适宜在黄淮海大部分地区种植推广。河北石家庄是本组区域试验最理想的试点。In order to determine the high yield and stable yield of the trial varieties of summer sown silage maize in Huanghuaihai Region in 2020,and to provide reasonable analysis methods and theoretical references for further variety promotion and planting,data from 15 varieties(lines)and 13 pilot sites of the 5000 seedlings per 667 m^(2) density group regional trial of summer sown silage maize in the Huanghuaihai Region in 2020 were selected.The analysis method of genotype main effects and genotype×environment interaction(GGE)biplot was applied to analyze the high yield and stable yield of the trial varieties,as well as the differentiation and representativeness of the pilot sites.The results showed that the varieties with high yield and stable yield were Wannongke Silage 6,Chuandan 99,Lian Silage 101,and Yuqingyu 9,which were also the ideal varieties in this group of regional trials.The ideal variety is suitable for planting and promotion in most areas of Huanghuaihai Region.Shijiazhuang City,Hebei Province is the most ideal pilot for this regional trial.
