Principal components analysis showed that the first four principal components variance accumulation contribution rate amounts to 89 . 53 % , which reflected most of the variance information as listed characters above 通径分析结果显示，直接通径系数大小排序，产量因素性状依次为单株成铃单铃子棉重子指衣分；纤维品质性状依次为纺纱均匀性指数麦克隆值整齐度伸长率比强度2 . 5 %跨长。

Quality besides micronaire value and elongation of relevance not significant , other quality traits of both showed significant level ; yield and quality traits associated single boll weight and the first half of the average length uniformity index significantly related , and the breaking strength of correlation was significant , and micronaire value was negatively correlated ; lint and micronaire value elongation reached significant levels and a very significant level , and on average half the length uniformity index , breaking strength of correlation was significant but was negatively correlated 品质性状间除了麦克隆值与伸长率的相关性不显著之外，其余品质性状间均呈现出极显著水平；产量性状与品质性状的相关性中单铃重与上半部平均长度、整齐度指数相关性显著，与断裂比强度相关性极显著，与麦克隆值呈负相关；衣分与麦克隆值、伸长率分别达到显著水平和极显著水平，与上半部平均长度、整齐度指数、断裂比强度等相关性极显著但呈负相关。
