摘　　要：为了明确几种分析方法对杂种棉后代综合评价的异同,于 2002—2003 年通过聚类分析、关联度分析以及多目标综合值评定分析原理对 10 个杂种棉后代在不同生态点的主要农艺及经济性状进行了分析.结果表明:3种分析方法对杂种棉后代的综合评价趋势基本上一致.从纤维品质来看,以湘 Z-010,湘 Z-004,湘 Z-008,湘 Z-007纤维品质较好.从产量性状来考虑,以湘 Z-001,湘 Z-002,湘 Z-004 产量较高.从湖南定位 50~60 支纱区划方针和产量性状来看,以湘 Z-004 表现最好,属于高产优质品种.In order to study the similarities and differences of the comprehensive assessment on hybrid cotton offspring, the main agronomic and economic characters of ten hybrid cotton in different ecology site have been analysised by means of cluster analysis、the interrelative methods of gray systematic theory and various target comprehensive analysis.The study showed that:the comprehensive assessment tendency of ten hybrid cotton offsprings were essentially unanimous by three kinds analysis means,as for the fiber quality characters,the fiber quality of XiangZ-010,XiangZ-004,XiangZ-008, XiangZ-007 were better.As for the yield properties,the yield of XiangZ-001,XiangZ-002,XiangZ-004 were high.According to orientation 50s^60s yarn and the yield properties,XiangZ-004 demonstraled good yield and fiber quality in Hunan.
