摘　　要：对感染小麦条锈病的８２份小麦品种（系）进行抗锈性鉴定，结果将８２份品种（系）分为高度慢锈性品种、中度慢锈性品种、耐锈性品种、中度感锈性品种和高度感锈性品种等５大类型。通过Ｂａｙｅｓ判别分析，分别建立了５个判别函数，其符合率为９７．５６％．Slow stripe rusting resistance in 82 wheat varieties (lines) was identified at the boot stage of plant development in field.5 resistant types were dirived from 82 varieties by cluster analysis:high slow stripe rusting varieties,middle slow stripe rusting varieties,durable stripe rusting varieties,middle susceptible stripe rusting varieties and high susceptible varieties etc.5 distinguish functions were established with Bayes analysis,and their fit rate was 97.56%.
