摘　　要：为明确我国不同种、地理来源和毒素化学型小麦茎基腐病菌的致病力分化情况,采用纸塔法对来自全国9个省市80个采样点分离的224株小麦茎基腐病菌进行致病力分析。结果表明,不同种镰刀菌的致病力不同,黄色镰刀菌Fusarium culmorum,禾谷镰刀菌F.graminearum,假禾谷镰刀菌F.pseudograminearum及亚洲镰刀菌F.asiaticum致病力强于其他种。F.culmorum致病力显著高于F.pseudograminearum和F.asiaticum,而F.pseudograminearum,F.graminearum及F.asiaticum三者之间无显著性差异。中华镰刀菌F.sinensis,木贼镰刀菌F.equiseti,锐顶镰刀菌F.acuminatum致病力较弱,三者间苗期致病力无显著性差异;多数省份F.pseudograminearum群体间致病力无显著差异,仅山东F.pseudograminearum群体的致病性显著低于河南群体;此外,产毒类型为3ADON的F.pseudograminearum群体致病力显著高于15ADON群体。In order to determine the pathogenicity variation of different species,originating regions and trichothecene chemotypes of the pathogens of Fusarium crown rot in China,a paper tower method was used to screen 224 strains collected from 80 sampling sites in nine provinces in China.The results showed that the pathogenicity of different species of Fusarium was significantly different.Among all the Fusarium species,Fusarium culmorum,F.pseudograminearum,F.graminearum and F.asiaticum had stronger pathogenicity than other species.Virulence of F.culmorum was significantly higher than that of F.pseudograminearum and F.asiaticum,and among F.pseudograminearum,F.graminearum and F.asiaticum,there was no significant difference in pathogenicity.F.sinensis,F.equiseti and F.acuminatum showed weak pathogenicity,and there was no significant difference among them.There was no significant difference in pathogenicity among F.pseudograminearum population in most provinces,except that the pathogenicity of F.pseudograminearum population in Shandong was significantly lower than that in Henan population.The virulence of F.pseudograminearum population with 3ADON chemotype was significantly higher than that of 15ADON population.
