摘　　要：从山东省8个地(市)及四川省重庆分离和收集到10个番茄枯萎病菌菌株,在进行专化型测定的基础上,用番茄等位基因系品种Improved Pearson(IP)和Pearson VF-(?)(VF-(?))作为鉴别品种,采用土壤接种和孢子悬浮液沾根接种法对所获菌株进行小种鉴定。结果表明,10个菌株均能侵染IP 品种并引起发病,不能侵染VF-(?),根据对鉴别品种的反应特性,所有供试菌株均属于尖孢镰刀菌番茄专化型1号生理小种(Tusarium ax(?)spo(?)m (?)sp.Lycopersici racel)。本试验还对该小种的生物学特性进行了初步研究。Ten isolates of Fusarium oxysporum f.sp.lycopersici collected from 8 regions ofShandong Province and Chongqing of Sichuan Province were tested on the near isogemicline cultivars Improved Pearson(IP)(Susceptible to race 1)and Pearson VF-11(VF-11)(resistant to race 1 and susceptible to race 2)by methods of inoculating soil and plant root.The results showed that IP was susceptible to all tested isolates and VF-11 resistant.All iso-lates are suggested to belong to Fusarium oxysporum f.sp.lyeopersici race 1.This is thefirst record in China.The characteristics of race 1 are also described.
