摘　　要：小麦叶锈病是一种重要的小麦病害．培育和种植抗病品种是最为经济有效的防治方法。我国在小麦抗病育种工作中引入了1BL／1RS易位系，已知小麦抗病基因Lr26、Pm8、Yr9和Sr31均位于1BL／1RS易位系上。Lr26 and Lr19 are two known important wheat leaf rust resistance genes. The positive and negative markers of the two genes have been developed at present. A total of 17 commercial wheat cultivars collected from Sichuan province were inoculated with 14 Chinese Puccinia triticina races for gene postulation in the green- house and used to detect Lr26 and Lr19 by multiplex PCR, respectively. The results showed that Lr26 was detec- ted in six wheat cultivars, and no cultivar was found to carry the Lr19 gene. The multiplex PCR can be widely used for marker-assisted selection of Lr26 and Lr19.
