摘要
对2006年在吉林省内各市、县田间采集的稻瘟病标样中分离出的148个有效单孢菌株,用中国稻瘟病菌生理小种鉴别品种,鉴定出7群25个中国小种,优势种群为ZE群,优势生理小种为ZE1,其次是ZG1和ZA57。同去年相比中国小种的优势小种无变化,两年间的频率差距并不显著。
One hundred forty-eight mono-spore strains were separated from the samples of rice blast which were collected in each county and city in Jilin province in 2006.7 groups with 25 physiological races were identified by comparing with China verified strains, among which ZE group was dominant group, ZE1 was dominant physiological and ZG1 and ZA57 were the secondary physiological races. The dominant physiological race of Jilin did not change to compare the last year, and their frequency difference was not remarkable in two years.
