摘 要 ：本文以32个低酚棉品种（系）为材料，对10个产量、纤维品质性状进行的遗传分析结果表明：低酚棉多数产量构成因素与皮棉产量为正相关，提高衣指、降低籽指虽可提高衣分和单株结铃数，但不利于增加单铃重；高产、优质的矛盾主要表现在纤维长度、比强度与衣分和单株结铃数有较强的负相关。在较大群体的基础上，通过早代的正向选

Abstract:Ten characters of 32 glandless cotton genotypes were studied for genetic analysis. It was found that most yield components were positively correlated with lint yield, and main fiber quality characters, including 2.5% span fiber length, fiber strength and micronaire value, were negatively correlated
