摘　　要：为研究2013年湖南省棉花品种区域试验B组中参试品种与环境的互作关系,科学评价参试品种与试点,从而为品种审定、品种在生产中的有效利用及试点遴选提供理论依据。采用具有直观分析农作物两向数据的GGE双标图软件对参试品种的丰产性与稳定性、理想品种选择、品种适宜种植区域划分、各试点的代表性和鉴别力及理想试点选择等方面进行了分析。结果表明:2013年湖南省棉花品种区域试验B组各品种(系)皮棉产量的基因型、环境(试点)、基因型与环境互作效应均达极显著水平,其中环境主效(试点)、基因型主效及基因型与环境互作效应分别占处理变异平方和的57.99%、13.54%、28.48%;丰产性最好的品种是B3,稳产性最好的品种是B5,但最理想的品种是B3;大通湖管理区、君山和湖南省棉花科学研究所试点为最理想试点。The yield and stability of cotton cultivars, the pilot representative and discriminability, thescreening of ideal trial sites and ideal cultivars, cultivars suitable for cultivation of a regional division werecomprehensively evaluated by GGE biplot in Hunan Cotton Cultivar Regional Trail group B in 2013, in orderto study the interactions of testing cultivars and the environment, scientifically evaluate testing varieties andtesting sites, and provide the theoretical basis for cultivar assessment, application and suitable planting areaselection. The results showed that： genotype, environment, and genotype environment interaction effects of lintyield reached a significant level, in which the main environmental effect, the main effect of genotype andgenotype environment interaction effects accounted for 57.99% 13.54% and 28.48% of the squares variationsum respectively. We concluded that B3 was the most ideal cultivar for its high yielding, B5 was the bestcultivar for its stable yielding, and Datonghu, Junshan and Hunan Cotton Science Institute were the most idealtest sites.
