以2021-2022年江苏省区域试验中25个糯玉米品种在9个试点的鲜穗产量和品质性状数据为研究对象，应用GGE双标图法分析糯玉米品种的产量及区域适应性，对试点的区分力和代表性进行评价。应用GYT双标图法分析糯玉米品种的品质性状、产量和品种×性状间的互作特性，并对参试品种进行综合评价。结果表明，2021年复试品种浙糯208、糯YH1113综合表现优良；2022年复试品种润扬白糯具有较强的地域性，适宜在徐州、淮安等地种植。连甜糯909适应性较强，综合表现优良。泰兴和海门试点的代表性和鉴别力较强，是较为理想的试验点。

In this study, the fresh ear yields and quality traits of twenty five waxy maize varieties during 2021 to 2022 were collected from nine sites in Jiangsu province to analyze the productivity,and adaptability of waxy maize by GGE biplot. In additionally, the distinctiveness and representativeness of test sites were evaluated. GYT biplot analysis was used to analyze quality traits, yields and cultivar-trait interactions of waxy maize varieties, comprehensively assess these test varieties. The results showed that, two maize varieties Zhenuo208 and NuoYH1113 had a better comprehensive performance among the second-trial maize varieties in 2021. Among those second-trial maize varieties in 2022, maize variety Runyangbainuo is suitable for growing in Xuzhou and Huai'an because of its strong regional character, while Liantiannuo909 showed strong adaptability and a comprehensive performance. The Taixing and Haimen pilots have strong representativeness and distinctiveness among the test sites, considered to be ideal test sites.
