摘　　要：通过在盛花期对7个品系光合速率和含糖量的测定,分析其与纤维品质和产量性状的灰色关联度,结果表明:盛花期光合速率与衣分和籽棉产量关联系数最大,叶片含糖量与衣分和果枝层数关联系数最大。The paper through the determination of photosynthetic rate and the determination of the sugar content of 7 strains in the flowering period, and to analyze the grey correlation degree of them and fiber quality、yield traits . Results showed that：the correlation degree of photosynthetic rate and seed cotton yield and lint percentage was high,sugar content in leaf and lint percentage and fruit numbers had higher correlation degree .

关 键 词：棉花 光合速率 含糖量 纤维品质 产量
