本文阐述了在研究小麦寄主和叶锈菌之间的相互关系时,用毒力频率的研究方法来代替分小种测定小麦抗叶锈性方法的优越性。我科研组采取毒力频率来研究河北省小麦品种和河北省叶锈菌的相互作用,我们认为:这种研究方法能直接反应品种与菌株之间相互作用的情况,对生产者和抗病育种工作者提供的信息,要比小麦叶锈菌小种鉴定提供的以编号对小种命名的小种名单要有用得多。毒力频率研究法目前也被应用于小麦白粉病和稻瘟病。
This article describes the superiority of the method of virulence frequency to replace the method of determining leaf rust resistance of wheat in the study of the correlation between wheat host and leaf rust. Our research group takes the frequency of virulence to study the interaction between wheat varieties in Hebei Province and the leaf rust in Hebei Province. In our opinion, this research method can directly reflect the interaction between varieties and strains, The information provided by the workers is much more useful than the racial list provided by the identification of the wheat leaf rust races. The virulence frequency research method is also applied to wheat powdery mildew and rice blast.
