通过大棚内摩擦接种，研究了20个烟草品种发生烟草脉带花叶病毒(Tobacco vein banding mosaic virus，TVBMV)的症状特征和对TVBMV的抗性。TVBMV的症状因品种是否携带抗PVY的va位点和抗TMV的N基因而异。其典型症状为脉带花叶、深绿色斑块。vava基因型烟草品种(NC55,TN86)耐TVBMV，VaVa基因型品种(K326,云烟87和云烟97等)感TVBMV。供试品种对TVBMV表现为耐病或感病，缺乏持久抗性。

Symptoms and resistance to TVBMV (Tobacco vein banding mosaic virus,TVBMV) of 20 tobacco cultivars were studied by mechanical inoculation in green house. TVBMV symptoms on tobacco cultivars varied due to va locus conferring resistance to PVY and N gene conferring TMV resistance, with typical symptoms of vein banding mosaic and dark green mottle. Genotype vava cultivars (NC55,TN86) were tolerant to TVBMV,while genotype VaVa varieties (K326,Yunyan87 and Yunyan97) were susceptible to TVBMV.
