在病害三角关系中 ,病原物的致病性及寄主的抗病性是决定病害发生与否的内在因素。小麦叶锈病是一种世界性病害 ,人们已对小麦叶锈菌生理分化和小麦抗叶锈基因分析作了大量的研究。在本文中综述了这两方面的国内外研究进展 ,以期为我国小麦叶锈病的研究提供有参考价值的资料 In the triangle of diseases, the pathogenicity of the pathogen and the resistance of the host are the internal factors that determine whether the disease occurs or not. Wheat leaf rust is a worldwide disease, people have made a lot of studies on the physiological differentiation of wheat leaf rust and wheat leaf rust gene analysis. In this paper, the progress of both domestic and foreign research are summarized in order to provide valuable information for the study of wheat leaf rust in our country
