抗番茄黄化曲叶病毒番茄种质资源的鉴定与筛选

番茄黄化曲叶病毒（Tomato yellow leaf curl virus, TYLCV）病是威胁广东省番茄生产的主要病毒病害. 为给番茄抗病毒育种工作积累材料基础，本研究采用基于TYLCV侵染性克隆的番茄抗病性测定方法，对103份番茄材料进行了抗TYLCV鉴定，获得抗病番茄材料8份、耐病材料14份，这些材料可用于后续番茄抗TYLCV育种及其抗病机理等相关研究.

Identification and screening of tomato germplasm resources resistant to tomato yellow leaf curl virus

Tomato yellow leaf curl virus (TYLCV) imposes the major threat to tomato production in Guangdong province. In order to obtain TYL (V-resistant tomato) germplasm resources, a viral infectious clone-based resistance identification method was established, and by using this method, the interaction of 103 tomato germplasm materials with the virus was then tested in this study. The results showed that among the tested tomato germplasms, 8 materials were resistant, and 14 were tolerant, to TYLCV. The obtained tomato resources may be used for the breeding of virus-resistant varieties, as well as further study on the potential mechanism related to tomato TYLCV resistance.
