摘要
利用中国统一的 7个稻瘟病菌鉴别品种对 2 0 0 2 2 0 0 3年采自贵州省黔南、黔东南、黔西南、遵义、毕节、铜仁、六盘水和贵阳等八个地区 2 2个县 (市 )的 12 9个稻瘟病菌有效单孢分离菌株进行接种鉴定。共鉴定出 6群 2 9个生理小种 ,其中 ,ZB群小种的出现频率达 49.61% ,ZA群小种的出现频率为 3 3 .3 3 % ,这两个种群为贵州省稻瘟病菌的优势种群和次优势种群。
One hundred and twenty-nine isolates obtained from rice blast specimen collected from 8 areas-Qiandongnan, Qianxinan, Qiannan, Zunyi, Bijie, Tongren, Liupanshui and Guiyang, which included 22 counties in Guizhou Province were assessed on 7 Chinese vnitive rice cultivars through inoculation. Total 6 race population including 29 different races were identified, in which race population ZB was the predominant one with a incidence frequency of 49.61%, followed by race population ZA with a incidence frequency of 33.33%. These two race populations were respectirely the predominant and Sub-predominant tice blast in Guiahou Province.
