双标图法分析大豆多点试验中品系产量稳定性及试点代表性

GGE-Biplot Analysis on Yield Stability and Testing-site Representativeness of Soybean Lines in Multi-environment Trials

采用GGE双标图法对2008-2009年黑龙江省5个试验地点的9个大豆品系试验数据进行分析。结果表明：嫩00-2111属于高产、稳产性较好的品系,平均产量2 508.1 kg·km^-2;庆农05-1071和庆农05-1028在大庆试点表现较好,其产量分别是3 513.8和3 434.8 kg·km^-2,具有特殊适应性,在局部地区有推广价值。在5个试点中,杜蒙试点最好,既具有代表性又具有较强的鉴别力。

In this study,GGE-biplot method was used to analyze the data of soybean multi-environment trials from 2008 to 2009.Nine lines of soybean were tested in five sites.The results showed that Nen 00-2111 had higher yield and better yield stability than other lines.Qingnong 05-1071 and Qingnong 05-1028 possessed special adaptabilities,so it had promotional values in some areas.＇Dumeng＇ testing-site of Heilongjiang province was the best representative testing site and had better discrimination than other sites.
