利用７个白叶枯菌群，对山东水稻生产上主要种植的５个品种进行了抗性接种鉴定。结果表明，５个品种对６个菌群表现为抗到高感。Ｈ３０１对６个菌群平均表现中抗，对致病力较弱的ＣＲ６表现抗性。ＣＲ３因致病力不稳定，５个品种都没有发病。
Seven populations of Bacterial blight were used to identify five main cultivars in Shandong rice production. The results showed that the five cultivars showed resistance to high susceptibility to 6 bacterial populations. H301 showed average resistance to the six bacterial populations and showed resistance to the weaker virulence of CR6. CR3 due to the virulence instability, five varieties have no incidence.
