摘 要：
１９８７～１９９０年以辽宁、河北、山东、山西等地采集的菌源，在７０个谷子品种上接种，进行粟锈菌（Ｕｒｏｍｙｃｅｓｓｅｔｔａｒｉａｅ－ｉｔａｌｉｃａｅＹｏｓｈ）生理分化研究。发现不同来源粟锈菌存在明显的生理分化现象，并筛选出１３个鉴别寄主。以２５个不同地区的粟锈菌接种上述鉴别寄生的结果，将粟锈菌划分为１０个生理小种（或类型）。并发现粟锈菌的两个新寄主—珍珠粟（Ｐｅｎｎｉｓｅｔｕｍｔｙｐｈｏｉｄｅｓ）和野稗草（Ｅｃｈｉｎｏｃｈｌｏａｃｒｕｓｇａｌｌｉ（Ｌ）Ｂｅａｕｖ）。粟锈菌生理分化研究，为抗病育种和引种提供了依据．

摘 要：
The uredial samples of the millet rust collected from Liaoning, Hebei, Henan,Shandong, Shanxi, Jinn Provinces. and so on. Identification was carried on in greenhouse. It was found that the millet rust fungi showed physiological specilizations.Zbout 70 millet varieties have been screened for the selection of identifing host.13 arieties were employed as the differential varieties.From the rust of identification of the uredial samples,it was found these samples comprised 10 races.According to the field test of the rust resistant identification, there was no immune varieties and the resistances of those varieties have had a great difference.In the course of the experiment.The authors had found two new hosts (Pennisetum typhoides and Echinochloa crus galli)of Uromyces setariae-it alicae Yosh.
