芸薹根肿病菌(Plasmodiophora brassicae)存在生理小种分化现象,国际上通常采用Williams鉴别系统~([1])和欧洲根肿病菌鉴别寄主(ECD)系统~([2])鉴定根肿病菌生理小种。我国尚没有研究出适合本国根肿病菌生理小种鉴定的鉴别寄主系统。国内学者研究根肿病菌生理小种通常采用Williams鉴别系统~([3])。为了明确江西省蔬菜根肿病菌致病性分化及病菌小种的变化趋势,作者采用
Plasmodiophora brassicae has the phenomenon of physiological racial differentiation. Internationally, Williams differential system ~ ([1]) and European Coophead pathogen identification host (ECD) system ~ [2] Physiological race. China has not yet developed for the identification of the domestic clubroot physiological races identification host system. Domestic scholars to study clubroot physiological races commonly used Williams authentication system ~ ([3]). In order to clarify the pathogenic differentiation of vegetable clubroot in Jiangxi Province and the change trend of the germ races,
