摘　　要：为全面分析京津冀早熟夏玉米参试品种的适应性、丰产性、稳定性以及各个试验点的鉴别力和代表性,本研究通过对2019年该区域试验产量和主要穗部性状表现构建GGE双标图,对18个品种(含对照)在10个试验点的产量、穗长、穗行数和千粒重性状进行综合分析。结果表明,京科976和京农科829的丰产性和稳定性较好;北京顺义试验点最接近理想环境,对产量、穗长、穗行数、千粒重等4个性状均具有较好的鉴别力。To comprehensively analyze the adaptability, yielding ability and stability of early summer maize varieties tested in The Beijing, Tianjin and Hebei region, as well as the discrimination and representativeness of each test site, the yield, panicle length, panicle row number and 1 000-grain weight of 18 varieties(including control) were comprehensively analyzed at 10 test sites by constructing GGE biplots of experimental yield and main panicle traits in 2019 in this study. The results showed that Jingke 976 and Jingnongke 829 had good yield and stability. The experimental site in Shunyi distract of Beijing was closest to the ideal environment, and had good identification ability for yield, panicle length, panicle row number and 1 000-grain weight.
