摘要/Abstract

摘要：

采用遗传力校正的GGE双标图分析方法，对以安庆、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,基于皮棉产量进行品种生态区划分，并对划分结果进行信息比（IR）校正，为长江流域棉区棉花品种的选择提供科学依据.结果表明：长江流域棉区可以划分为3个棉花品种生态区，即以简阳和射洪为代表的“四川盆地棉花品种生态区”、以南阳和襄阳为代表的“南襄盆地棉花品种生态区”和涵盖其余试验点的“长江流域主体棉花品种生态区”.

Abstract: By using the heritability-adjusted GGE biplot analysis method, and taking the trial sites Anqing, Nanyang, Huanggang, Jingzhou, Wuhan, Xiangyang, Changde, Yueyang, Nanjing, Nantong, Yancheng, Jiujiang, Jianyang, Shehong, and Cixi as the representative cotton-planting areas in the Yangtze River basin, the ecological regionalization of cotton varieties in the basin was made based on the lint cotton yield, and the regionalization results were adjusted by the information ratio (IR) method, aimed to provide scientific basis for the selection of cotton varieties in the cottonplanting areas of the basin. The cottonplanting areas in the Yangtze River basin could be divided into three ecological regions, i.e., the “Sichuan basin cotton region” with Jianyang and Shehong as the representative, the “NanXiang basin cotton region” with Xiangyang and Nanyang as the representative, and the “majority complex cotton region in the Yangtze River basin” including all the other sites in the basin.
