烂铃是影响棉花产量和纤维品质的重要因素。为了明确烂铃对棉花产量因子和纤维品质的影响程度，以11个常规种和11个杂交种为试验材料，分别测定了烂铃与正常铃的产量因子和纤维品质性状。结果表明：与正常铃相比，烂铃的铃重、子指和衣分3个产量因子均出现了极显著差异，其中，铃重和子指分别降低了19.22％和15.33％，衣分提高了1.31％；烂铃纤维的马克隆值、断裂比强度、伸长率、上半部平均长度和整齐度也出现了极显著差异，分别下降了20.37％、10.18％、9.26％、4.21％和3.27％。并分析了烂铃对杂交种与常规种产量因子和纤维品质的影响，结果显示，除对衣分的影响差异达到了显著水平外，对铃重、子指以及纤维品质性状的影响差异均不显著。

Cotton boll rot was an important factor affecting cotton yield and fiber quality.In order to clear the influence degree, in this research, with 11 conventional varieties and 11 hybrids as experimental materials, the normal bolls and rot bolls were tested respectively on factors affecting yield and fiber quality.The results showed that compared with normal boll, boll weight, seed index and lint percentage of rot bolls had significant differences.The boll weight and seed index were reduced by 19.22% and 15.33%, the lint percentage was increased by 1.31%.Fiber traits which were tested also had significant difference compareing with normal bolls.The micronaire, breaking tenacity, elongation, upper half mean length, uniformity were respectively reduced by 20.37%, 10.18%, 9.26%, 4.21% and 3.27%.The influence of boll rot on conventional varieties and hybrids were studied respectively, the results showed that the effect on lint percentage was significantly different, and the boll weight, seed index and fiber traits had not obvious difference.
