摘  要:
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。

摘  要:
The procedures of testing for virulence frequency and its application in the study of leaf rust of wheat were introduced. Wheat varieties and leaf rust samples of Hebei province were collected in 1982 and study of interaction between host and pathogen was made in 1983. The results expressed by virulence frequency showed that this method of investigation provided directly the information of the interrelationship between the wheat varieties and the rust fungus. It seems that this information is much more useful than providing a list of races named by numbers for the breeders and the wheat growers. Improvement of this method and the application of this method to the studies of powdery mildew of wheat and rice blast were also discussed.
