摘　　要：[目的]研究高品质陆地棉株型、产量及品质3个性状间的典型相关性。[方法]于2006年采用田间试验完全随机区组设计,对26份高品质陆地棉品种(系)的16个数量性状进行典型相关分析。[结果]株型性状分别与产量性状、品质性状间的第1个典型相关系数达0.01显著水平,占总相关信息的69.36%和70.08%;产量与品质性状间的第1个典型相关系数达0.05显著水平,占总相关信息的51.36%,以上典型相关系数依次为0.8894、0.8979、0.7831。在这些性状中起主要作用的性状有:株高、主茎节距、果枝台数、衣分、衣指、比强度、麦克隆值、整齐度指数。[结论]该研究结果对于利用陆地棉株型和产量性状间接选择品质性状具有一定的指导意义。[ Objective ] The purpose was to study the canonical correlation among three waits of plant type, yield and quality of upland cotton with high quality. [Method] In field test with complete randomized block design in 2006,sixteen quantitative traits of 26 upland cotton varieties or lines with high quality were made for the canonical correlation analysis. [Result] The first canonical correlation coefficients （CCC） between plant type waits and quality waits as well as between plant type traits and quality traits were significant at 0.01 level and amounted for 69.36% and 70.08% of the total correlation information resp.The first CCC between yield traits and quality traits was significant at 0.05 levels and amounted for 51.36% of the total correlation information, The above CCCs in order were 0.889 4,0.897 9,0.783 1.The Waits that played the main role in theses Waits were plant height,length of stem node, number of fruit branch, lint percentage,lint index, fiber strength, micronaire, uniformity. [ Conclusion] These results will have certain significance for indirect selection of quality waits using plant type and yield traits in upland cotton.
