摘要: 利用棉花(Gossypium hirsutum)雄性不育不仅可以培育优质的杂交种, 还能提高棉花制种效率并降低制种成本。该研究以冀2658系及其同核异质不育系冀2658A为母本, 以6个恢复系为父本配制12个杂交组合。利用F1代研究棉花细胞质对棉花农艺性状、抗病性、种子中粗脂肪和粗蛋白含量、纤维品质及产量性状的影响。结果表明, 冀2658A的细胞质主要影响棉花杂交种F1代的产量相关性状、黄萎病抗性及棉籽粗脂肪含量等, 表现为衣分显著降低(比对照组低1.61%), 黄萎病抗性增强(黄萎病指数比对照组低18.29%), 棉籽中的粗脂肪含量降低(比对照组低2.88%)。该研究初步探讨了胞质不育型细胞质对陆地棉主要性状的影响, 为陆地棉胞质雄性不育系的利用提供了理论参考。

Abstract: The use of a cotton cytoplasmic male sterility (CMS) line can lead to breeding high-quality cotton seeds and also improve the efficiency of the preparation and decrease the cost of seed production. This study used the JI 2658 and JI 2658A cotton lines, which have the same nuclear background but different cytoplasm as female parents, with another six restorer lines as the male parent; 12 crosses were made according to one-to-one correspondence. The F1 hybrids were used to study the cotton cytoplasmic effects on agronomic traits, disease resistance, fat and protein content, fiber quality and yield. The CMS cytoplasm effects of the 2658A line on cotton hybrids mainly involve lint yield, verticillium wilt resistance and fat content-related characters. As compared with controls, crosses showed reduced lint yield and fat content of seeds by 1.61% and 2.88% and verticillium wilt resistant increased by 18.29%. These results are preliminary in understanding the CMS cytoplasm effects on upland cotton and will be important for using upland cotton CMS.
