采用不完全双列杂交方法，将11个棉花自交系按7×4组成28组进行杂交并获得杂交材料，再加上亲本和对照组一共40个材料，并对其籽棉重、皮棉重等产量性状以及伸长率、断裂比强度等品质性状进行调查收集数据，再利用DPS软件计算其配合力，用SPSS软件对其进行相关性分析。结果显示，一般配合力高的亲本有S4、S6、S9、S11，特殊配合力较高的亲本组合有S4×S8（单株成铃数）、S5×S8（单铃重、籽棉重）、S6×S11（皮棉重）、S3×S8（衣分）、S3×S11（断裂比强度、伸长率）、S2×S8（整齐度指数）；产量构成因素与籽棉产量的相关系数大小依次为单铃重＞皮棉重＞单株成铃数＞衣分。这一信息启示我们，...

With the method of incomplete diallel cross, the hybrid materials were obtained from the crossing of 11 cotton inbred lines which were formed into 28 combinations according to 7 ×4.Adding the par-ents and control group, total 40 materials were investigated in the yield traits such as seed cotton weight and lint weight, and the quality traits such as extensibility and specific strength.The combining ability was calcu-lated by DPS software, and the correlations were analyzed by SPSS software.The results showed that the par-ents material S4, S6, ...
