基于R语言的GGE双标图在玉米品种区域试验中的应用

为了鉴定高产稳产玉米新品种以及为玉米高产栽培提供理论依据，通过基于R语言的GGE双标图法分析了10个玉米新组合在四川省甘孜州高海拔地区生态条件下的丰产、稳产性和适应性，同时分析了5个试验点对参试组合的辨别力和代表性。结果表明：‘康玉试0903’和CH327 2个组合高产且稳产；而SZ694较高产，但稳产性稍差，在海螺沟试验点有特殊适应性。综合各试验点的区分力和代表性，丹巴、九龙和海螺沟较好：九龙和海螺沟的区分能力强，丹巴试验点的代表性最佳。

Application of GGE-biplot Based on R Language in Regional Trial of Maize Varieties

This paper used GGE-biplot based on R language to analyze high-yield, stability and adaptability of maize yield, with ten new maize hybrid combinations planted in five ecological conditions of high altitude in Garze Tibetan Autonomous Prefecture, Sichuan Province, to provide references for identification of new varieties and maize high-yield production. Meanwhile, representativeness and discrimination of five different testing sites was analyzed. The results showed that, ‘Kangyushi 0903’ and CH327 were both the combination with a high and stable yield, and SZ694 had a relatively high yield also, but its stability was a bit poor, so it had a special adaptability in Hailuogou. In terms of discrimination and representativeness, Jiulong, Hailuogou and Danba had a better performance: Hailuogou and Danba had the best discrimination, while Danba site had the best representativeness.
