摘　　要：采用灰色关联度分析法,对不同来源的18个早熟棉花品种(系)的主要农艺性状与产量的关系进行了分析。结果表明:单株结铃、株高、节位与产量的关联度较高,其次是衣分、单铃重和单株果枝数,霜前花率与产量的关联度不高,病株率和病情指数与产量的关联度最低。The correlation between yield and main agronomic characters of 18 early-maturing cotton va-rieties（ lines） were studied using the grey relational grade analysis method.The results showed that the boll number per plant, plant height and fruiting branch sites had higher relational grades with yield, which were followed by lint, single boll weight and branch number per plant;the relational grade between pre-frost yield percentage and yield was lower, and that of disease index and percentage of disease plants with yield was the lowest.
