| 摘 要： | 在人工接种高病害压条件下,对当前生产上应用的13个油菜双低和杂交品种及14份资源材料进行了 对芜菁花叶病毒( TuMV)的抗性鉴定。结果表明,参试的13个油菜品种均不抗TuMV,但感病性低于对照品种中油 821。14份油菜资源材料间抗性差异显著,有3份材料表现高抗和中抗。大部分油菜推广品种表现的高发病率和 病情指数表明在病害流行地区和年份,这些品种不足以抵挡病毒病造成的损失。

| Abstract: | Resistance of twenty seven cultivars and germplasms in oilseed rape(Brassica napus) to turnip mosaic virus(TuMV) were evaluated by artificial inoculation.13 cultivars,which were currently applied in oilseed rape production,were all susceptible to TuMV.However,their disease indexes were lower than cultivar Zhongyou 821.Among 14 oilseed rape germplasms tested,3 showed high or medium resistance to TuMV.The results indicated that the tested cultivars of oilseed rape can not resist TuMV under severe epidemic conditions. |
