Susceptibility of 33 Lycopersicon species and varieties to Tobacco mosaic virus (TMV) and Cucumber mosaic virus (CMV) were studied. Plants were mechanically inoculated with the C/U1 strain of TMV and U/246 strain of CMV. Virus infection was checked by symptomatology, DAS ELISA and back inoculation (biotest). All the studied Lycopersicon species and varieties were susceptible to TMV-C/U1. L. esculentum Mill. convar. infiniens Lehm. var. flammatum Lehm., L. esculentum Mill. convar. fruticosum Lehm. var. speciosum Lehm. and L. esculentum Mill. convar. infiniens Lehm. var. validum Bail. showed extreme resistance to CMV-U/246. The other 30 species and varieties were susceptible to CMV-U/246. New compatible and incompatible host-virus relations have been reported. The extreme resistant Lycopersicon varieties could be used as resistance sources in tomato breeding.
研究了33种番茄属物种和品种对烟草花叶病毒（TMV）和黄瓜花叶病毒（CMV）的敏感性。用TMV的C/U1株系和CMV的U/246株系对植株进行机械接种。通过症状观察、双抗夹心酶联免疫吸附测定（DAS ELISA）和回接接种（生物测定）来检查病毒感染情况。所有研究的番茄属物种和品种均对TMV-C/U1敏感。普通番茄栽培变种无限生长型火焰番茄、普通番茄栽培变种灌木型美丽番茄和普通番茄栽培变种无限生长型健壮番茄对CMV-U/246表现出极高抗性。其他30个物种和品种对CMV-U/246敏感。报道了新的亲和与不亲和的寄主-病毒关系。极端抗性的番茄属品种可作为番茄育种的抗性资源。
