| 本文借助于GenStat的GGE双标图对2016—2018年马铃薯多点试验中的7个马铃薯参试高代品系在5个试点的产量及稳定性进行分析。结果表明，在参加多点试验的7个品系中，在丰产性与稳定性方面表现较好的是品系0773-2（G5）与1003-2（G2）。0904-134（G1）与0911-27（G6）既不高产，也不稳产。综合3年试验分析结果，参加多点试验的5个试点中，试点陇西（E3）的代表性与区分力综合表现好，其次为试点安定（E1），试点临洮（E2）与通渭（E5）的区分力与代表性相似，试点会宁（E4）的区分力与代表性较差， GGE双标图能够为马铃薯的新品种选育、产量稳定性评价提供快速准确的分析方法。 |
| 英文摘要: |
| The Biplot has been increasingly applied to intuitive analysis of genotype\|by\|environment data in crop variety. In this research, the yield and stability of 7 high\|generation of potato lines in 5 multipoint trials from 2016-2018 were analyzed using GGE Biplot with Genstat software. Through the analysis of the tested lines year by year, the results showed that 0773-2 (G5) and 1003-2 (G2) had better performance in terms of yield and stability among the 7 potato lines studied in this multipoint test. The 0904-134 (G1) and 0911-27(G6) had poor stability and yield among 7 potato lines. The GGE-Biplot explained the representativeness and discrimination of the test location, and divided the ecological area of the testing sites to make clearly the functional similarity of the testing sites. Based on the analysis results of the 3-years experiment, among the 5 testing sites in the multi\|point experiment, the representativeness and discrimination of testing sites Longxi (E3) were good, the second one was Anding (E1), the discrimination and representativeness of Lintao (E2) and Tongwei (E5) were similar, while that of testing sites Huining (E4) was worse than others. The GGE Biplot can scientifically and systematically evaluate the stability and yielding ability of high generation lines and provide a fast and accurate analysis method for the selection and breeding of new varieties of potato. |
