| 摘 要： | 采用GGE双标图分析方法对2000~2010年期间27组长江流域国家棉花品种区域试验以安庆、南阳、黄冈、荆州、武汉、襄阳、常德、岳阳、南京、南通、盐城、九江、简阳、射洪和慈溪等15个试验点为代表的长江流域棉区目标环境中可能存在的基于棉花纤维长度选择的品种生态区进行探索与划分，并对品种生态区划分结果进行信息比（IR）校正，以提高品种生态区划分的可靠性，为长江流域棉区棉花品种纤维长度的选择和推荐策略提供科学的决策依据。结果表明：我国长江流域棉区大致可划分为基于纤维长度选择的3个品种生态区，第1个品种生态区包括安庆、九江、武汉、南通、黄冈、常德和岳阳，第2个品种生态区包括荆州、盐城、南京和射洪，第3个品种生态区包括慈溪、简阳、襄阳和南阳。

| Abstract: | GGE biplot analysis method was adopted to explore and investigate the possible megaenvironments in the target cotton planting region with the trial locations including Anqing, Nanyang, Huanggang, Jingzhou, Wuhan, Xiangyang, Changde, Yueyang, Nanjing, Nantong, Jiujiang, Jianyang, Shehong and Cixi as the representatives for cotton fiber length selection in 27 independent sets of cotton variety trials in the Yangtze River Valley during the 2000~2010 periods, in order to provide the scientific basis for the decision-making of cotton variety selection and recommendation for the Yangtze River Valley. The Information Ratio(IR) adjustment method was implemented as a validate tool to ensure sufficient and necessary main principal component scores were selected in GGE biplot analysis. The conclusions showed that the cotton planting regions in Yangtze River Valley was divided into three distinct fiber length selection megaenvironments, namely,the first megaenvironment contains seven test environments including Anqin, Jiujiang, Wuhan, Nantong, Huanggang, Changde and Yueyang; the second megaenvironment contains four test environments including Jingzhou, Yancheng, Nanjing and Shehong; and the third megaenvironment contains test environment of Cixi, Jianyang, Xiangfan and Nanyang. |
