作者曾分别用Provvidenti和Green的芜菁花叶病毒(TuMV)株系鉴定谱,对我国十省(市)的TuMV主流分离物进行鉴定和归类,除确认C_1、C_4、C_5等3个株系外,尚有2类分离物不能按该标准归类。作者认为,我国十字花科蔬菜资源十分丰富,栽培地域广阔,生态地理差异显著,Provvidenti和Green鉴别寄主谱不能完全反映其实际差异,乃是合乎常理的。因此,根据我国的实际情况,寻求筛选新的鉴别寄主,并进行株系划分方法研究,甚属必要。本文是这方面研究工作的初步总结。
The authors identified and classified TuMV mainstream isolates from ten provinces (cities) of China using three lines of Provmidenti and Green (TuMV), respectively. In addition to identifying three strains of C_1, C_4 and C_5 In addition, there are two types of isolates can not be classified according to the standard. The author believes that cruciferous vegetables in our country are rich in resources, broad areas for cultivation and significant differences in ecological geography. Provvidenti and Green can not fully reflect the actual differences in the host spectrum, but it is not unreasonable. Therefore, according to the actual situation of our country, it is necessary to seek for the screening of new identification hosts and to study the division of strains. This article is a preliminary summary of research work in this area.
