摘　　要：用GGE双标图对2009—2010年度南方冬大麦品种区域试验进行分析,以图谱的形式阐述了参试品种在各试验点的表现、各品种的平均表现和稳定性、各品种的适应地区、各参试品种的相似性和环境的相似性及两品种之间的比较等问题,很好的解答了品种与环境互作的问题。双标图显示‘苏啤3号’是一个适应性很广的品种。产量相关性状的图谱分析表明:本年度试验中有效穗与产量相关性最高,是影响产量的制约因素。The cultivar evaluation of China southern winter barley trial using GGE biplot during 2009-2010 was reported.The following questions could be visually addressed from the biplots： the growth performance of each cultivar in a given test site,mean performance and stability of each cultivar,the most favorable environments for a given cultivar,similarity of a pair of cultivars or environments,the difference between a pair of cultivars and the interaction between cultivars and environments.The results on biplot indicated that Supi No.3 was a cultivar with wild adaptability.Graphic assessment of yield-related trails showed similarity of effective ears and yield was high in the test,and effective ear was the restrictive factor of yield.
