摘要
将根肿菌单孢分离技术和Williams生理小种鉴定方法结合,对中国9个大白菜主要产区的根肿菌进行单孢分离及生理小种鉴定。共获得281个单孢菌株,通过Williams鉴定,这些单孢菌株分别属于该系统中除5号生理小种之外的15个生理小种类型。其中4号生理小种所占比例最大,共191个,占67.97%,9个地区的优势生理小种均为4号小种。
We combined the single spore isolation technology and Williams identification method to isolate single spores of Plasmodiophora brassicae from nine major Chinese cabbage producing areas in China and identify their physiological races,to obtain more types of single-spore physiological races.A total of 281 single-spore stains were obtained and identified by Williams identification,these single spores belong to 15 types of physiological races other than No.5 physiological race in the system.Among them,191 single-spores were of the No.4 physiological race accounting for 67.97%.The dominant physiological race in the 9 regions was No.4.
