以一组闭花受精和开花受精棉花近等基因系为材料，对两种类型的棉花在纤维品质方面的差异进行了研究。试验结果表明，种子来源于闭花铃的各材料，它们又分离出的闭花铃与开花铃，其纤维品质无显著差异，各项主要纤检指标成正相关，并且纤维长度和整齐度相关显著。结果说明，如能在育种或良种繁育实践中利用棉花的闭花受精特性，在纤维品质方面不会存在问题。 Taking a group of near-isogenic lines of flowering and fertilization and flowering and fertilization cotton as materials, the differences in fiber quality between the two types of cotton were studied. The results showed that the seeds originated from the materials of the closed flowers, the flowers and the boll weighers had no significant difference in their fiber quality. The main indexes of the fiber were positively correlated, and the fiber length and uniformity were significantly correlated . The results showed that if the use of cotton in the breeding or breeding practice of the closed flower fertilization characteristics, there is no problem in terms of fiber quality.
