1997、1998年分别对安徽省28个县市的主栽稻区分得的30个菌株,在安徽农业大学农场(无病区)进行田间成株期测试,用全国统一的IR-26、Tetep、Java-14、南粳-15、金刚-30 5个鉴别品种,于孕穗期剑叶剪叶接种测定。结果表明,安徽水稻白叶枯病菌,除肥东菌株(Xo-01)与怀远菌株(Xo-71)属Ⅲ型外,多数菌株属Ⅱ型,而皖南和沿江稻区菌株致病力弱,多属0- Ⅰ型。
In 1997 and 1998, 30 strains isolated from main rice growing areas in 28 counties and cities in Anhui Province were tested on the farmland of Anhui Agricultural University (without disease area) and tested in the field with uniform national IR-26, Tetep, Java-14, Nanjing-15, King Kong -30 5 identification varieties, at the booting stage flag leaf cutting measured. The results showed that most of the isolates belonged to type Ⅱ except Xo-01 and Xo-71, while the isolates in Wannan and the Yangtze River had weak pathogenicity. Mostly 0- Ⅰ type.
