摘　　要：利用GGE双标图方法对江苏省2017年杂交晚粳组区试中14个品种的多点测试数据进行分析。基于试验点的区分力和代表性分析,发现此次区试的6个试验点均具有较强代表性。GGE双标图高产、稳产性结果显示甬优1526产量最高,其次是甬优7826、春优312;浙粳优7172稳产性最强,其次是春优312。理想品种分析结果显示甬优1526为最理想品种,既高产又稳产。这说明GGE双标图可有效且直观地评估和解释新品种的区试结果。In this study,the method of GGE-biplot was employed to analyze the dataset of the regional trail of late japonica hybrid cultivars of Jiangsu province in 2017.According to the evaluation result of discrimination and representativeness for trail sites,all the six sites possessed obvious feature of representativeness.The high yield and stability results of GGE-biplot showed that the cultivar Yongyou 1526 possessed the highest level of the yield,followed by Yongyou 7826 and Chunyou 312.However,Zhegengyou 7172 had the most prominent yield stability,followed by Chunyou312.The result of ideal variety analysis illustrated that Yongyou 1526 was the most ideal variety with high-yield and excellent stability.In conclusion,the GGE-biplot method can effectively and intuitively evaluate and interpret regional trail results for new varieties.
