番茄青枯病是一种世界性病害,近年在我国南方诸省,特别是湖南、四川、广东、广西、江西等省发病日趋严重,往往大片死亡,造成严重减产,成了番茄生产的重要障碍。为此,全国组成了番茄抗青枯病育种的协作组,以期育成抗青枯病的新品种。我所经过三年的研究从国内外的大量原始材料中 Tomato bacterial wilt is a worldwide disease. In recent years, the incidence of the diseases in the southern provinces of our country, especially in Hunan, Sichuan, Guangdong, Guangxi and Jiangxi provinces, has become more and more serious. It is often the result of large-scale deaths that have caused serious cuts in production and become an important obstacle to tomato production . To this end, the country formed a collaborative group of tomato resistance to bacterial wilt breeding in order to bred new varieties resistant to bacterial wilt. I have gone through three years of research from a large amount of raw materials both at home and abroad
