用我国小麦条锈病菌(条中1、2、8、10、13、17、20、21、23、24、25、26、27、28和水源11致病类型)15个生理小种,在美国的12个小麦条锈病鉴别寄主上进行抗性鉴定.结果表明,美国的鉴别寄主对我国小麦条锈菌生理小种的鉴别能力很低。说明我国小麦生产上发生流行的15个生理小种与美国记载流行的25个生理小种没有相似之处。因此条锈病菌在不同的国家是自成流行体系,在不同流行体系内,应有各自的鉴别寄主.实践证明,国内自选鉴别寄主对国内小种最具有鉴别能力.美国鉴别寄主中的 MORO,可作抗源利用.
Fifteen physiological races of wheat stripe rust (1, 2, 8, 10, 13, 17, 20, 21, 23, 24, 25, 26, 27, 28 and water source 11 pathogen) The identification of 12 wheat stripe rust disease-resistant hosts in the United States was carried out for resistance identification.The results showed that the identification of the host of the United States on the identification of wheat stripe rust races in China is very low. It shows that there are no similarities among the 15 physiological races that prevail in wheat production in our country and 25 racial races popular in the United States. Therefore, the stripe rust bacteria in different countries is a self-contained system, in different epidemic systems, should have their own identification of the host.Practice has proved that the domestic self-selection of the identification of the most domestic species of the ability to identify the United States to identify the host MORO, Can be used for anti-source.
