上海农科院园艺所利用抗病育种手段,于1979～1983年育出优质抗病(TuMV)的青菜新品种“矮抗青”,现将该品种的育成及推广情况陈述如下。一、选育过程及良种繁育程序 1975～1977年收集上海菜区主要青菜地方品种500余份材料,进行小区观察,根据自然发病率、经济性状及产品综合评价进行选择,并同时对每个品种材料内感病植株取样分离鉴定所感染的病毒种类,选择原始材料。“矮抗青”(E78—04)是以虹五许东矮箕为原始材料,1975年进行自交,其后代又自交多代,每代均进行室内人工苗期接种病毒(TuMV),以及自然诱发抗性鉴定,筛选而获得的。
Horticultural Institute of Shanghai Academy of Agricultural Sciences using disease-resistant breeding means, from 1979 to 1983 bred high quality disease resistance (TuMV) new varieties of green vegetables, “short anti-green”, now the breed of breeding and promotion of the following statement. First, the breeding process and breeding program 1975 ~ 1977 collected more than 500 copies of the main vegetable varieties in Shanghai vegetable area for cell observation, according to the natural incidence, economic traits and comprehensive evaluation of products to choose, and at the same time for each variety Material samples of infected plants were isolated and identified the type of virus infection, select the original material. “Short resistance to the green” (E78-04) is based on the original material of Hongwu Xuandongui and selfed in 1975. The offspring also self-crossed for many generations, each of which performed indoor artificial seedling inoculation virus (TuMV) As well as naturally induced resistance identification, screening.
