摘　　要：辣椒叶脉斑驳病毒(Chilli veinal mottle virus,ChiVMV)为马铃薯Y病毒属(Potyvirus)的确定种,在我国烟草上的危害呈上升趋势,了解ChiVMV侵染烟草品种的症状和品种的抗性有利于病害防治。本文通过塑料大棚内摩擦接种,分析了21个烟草品种的症状特征和对ChiVMV的抗性。ChiVMV侵染烟草的典型症状为褪绿黄化、花叶、疱斑和叶缘下卷。按照国家标准GB/T 23224—2008,依据接种ChiVMV后14 d的平均病情指数,各品种对ChiVMV的抗性分别为:MD609,巴斯玛1号和云烟97为感病,MSK326,MS云烟87,MS云烟85,红花大金元等18个供试品种为高感。云南省烟草主栽品种缺乏对ChiVMV的抗性,ChiVMV的危害需要引起重视。The damage of tobacco caused by Chilli veinal mottle virus （ChiVMV） in China has in- creased, understanding ChiVMV symptoms on tobacco varieties and cultivars resistance could direct dis- ease management. In this study, the symptoms and resistance to ChiVMV of 21 tobacco cultivars were el- evated by mechanical inoculation in plastic tunnel. The typical symptoms of ChiVMV were chlorosis, yellowing, mosaic, blotch, leaf edge roll down. Cultivars of MD609, Basma 1 and Yunyan 97 were sus- ceptible to ChiVMV, other 18 varieties （MSK326, MSYunyan 87, MSYunyan 85 and Honghuada- jingyuan, etc. ） were highly susceptible to CbiVMV. No variety was resistant to ChiVMV from the tested Yunnan tobacco varieties. More attention should be paid to the impact of ChiVMV on tobacco.
