采用苗期人工接菌的方法鉴定了25份北欧小麦对河南省7个不同地区小麦白粉病菌分离物的抗性,同时利用与已知抗白粉病基因Pm2、Pm3f、Pm4、Pm6、Pm13、Pm16、Pm21和Pm24连锁的分子标记对其中抗性优良的材料进行基因检测。结果表明,8份材料对所有接种的白粉病菌菌株表现高抗或免疫;其中NGB7476和NGB7809携带Pm4a和Pm16基因,NGB7481和NGB9954携带Pm6和Pm16基因,NGB9955和NGB9956同时携带Pm4a、Pm6和Pm16基因,8份材料均不携带Pm2、Pm3f、Pm4b、Pm13、Pm21和Pm24基因。
The method of artificial inoculation in seedling stage was used to identify the resistance of 25 northern European wheat isolates to powdery mildew of wheat in 7 different areas in Henan Province. At the same time, the resistance to powdery mildew of Pm2, Pm3f, Pm4, Pm6, Pm13, Pm16 , Pm21 and Pm24 linked molecular markers in which the resistance of the material for genetic testing. The results showed that 8 of them showed high resistance or immunity to all the inoculated powdery mildew strains. Among them, NGB7476 and NGB7809 carried Pm4a and Pm16 genes, NGB7481 and NGB9954 carried Pm6 and Pm16 genes, NGB9955 and NGB9956 carried Pm4a, Pm6 and Pm16 genes simultaneously, No material contained Pm2, Pm3f, Pm4b, Pm13, Pm21 and Pm24 genes.
