Abstract：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.
