摘　　要：对GGE双标图在马铃薯区域试验中的应用进行评价.采用贵州省2年8个试点9个品种(系)组成的马铃薯区域试验产量资料,通过GGE双标图法,研究了马铃薯基因型与环境互作效应对试点代表性与鉴别力,以及品种丰产性与稳定性的影响.结果表明:在9个品种(系)中,(G7)26-13-1属于丰产性、稳定性高的品(种)系.在8个试点中,(E1)安顺和(E4)六盘水的代表性与区分力最好.GGE双标图为研究不同环境下马铃薯产量提供了更为科学、直观有效的分析方法.To test the application of GGE（Genotype ＋ Environrnent x Genotype）-biplot in a potato growing region. Adopting 2-years 8-pilot 9-variety potato regional test yield data in Guizhou Province, the potato geno- types and the environment interactive effect of the pilot representatives and flair and high yielding varietiesand stability were studied through the GGE double plotting method. The yield data of nine potato cultivars from eight testing sites were analyzed, with the result that （G7） 26-13-1 had the highest stability and production of all. Among the eight test sites, El（Anshun） and E4 （Liupanshui） were the best representatives of the overall testing sites, proving GGE-biplot to be one of the reliable methods that breeders could use for analyzing and evaluating the potato yield performance in regional trials.
