In this paper,eight main economy characters which were distributed in the 30 different part boll on BM1、BM6、 YM668 and HN109 were analyzed by Canonical correlation analysis and factor analysis.The result indicated that with the raise of high boll weight(rux1=0.6980),the lint percent(rux2=0.6556) would increase together,the uniformity(rux8=0.5399) and strength(rux6=0.3197) increased indirectly,but it would lead to certain degree disadvantage influence to the length(rux4=-0.3197) and micronaire(rux5=0.4799).
