摘　　要：应用因子分析法可把23份茎瘤芥品种资源的15个数量性状集约在5个主因子上,采用正交因子和斜交因子模型分析了性状间的遗传作用关系,并探讨了各因子间的关系及其生物学意义。23 varieties of tumorous stem mustard were planted in a random block designed with 3 replications. 15 quantitative characters were evaluated during the growth period. These characters were concentrated to five factors by factor analysis on the basis of correlation matrix. The orthogonal and oblique factor load matrices were analyzed for the genetic correlationship of characters. The biological meaning and the correlationship of factors were also discussed.
