1971~1996年从40余个国家(地区)引进14个科48属72种(包括变种)共11410份蔬菜遗传资源,其中20余种为国内稀有蔬菜,还有我国科研和生产急需的抗源材料、雄性不育系、耐热和耐低温等珍贵材料。根据我国不同地区的生态气候类型,与地方科研、生产单位结合对引进的5345份材料共同试种鉴定,筛选出40余个优良品种在生产上直接推广利用,获得了巨大的经济效益。选出的品种中有7个通过了省(市)品种审(认)定,共推广面积261khm2。大批引进的蔬菜优异资源被全国育种单位广泛用于培育新品种,获得了重大的社会效益和经济效益。
From 1971 to 1996, 11410 genetic resources of 72 species (including varieties) of 14 genera and 48 genera and 48 genera were introduced from more than 40 countries (including varieties), of which more than 20 species are domestic rare vegetables and the much-needed source of resistance to scientific research and production in China Materials, male sterile lines, heat-resistant and low-temperature resistant precious materials. According to the types of ecological climates in different regions of China, 5345 materials introduced from local scientific research and production units were jointly tested and identified. More than 40 fine varieties were screened out for direct utilization in production and huge economic benefits were obtained. Seven of the selected breeds passed the provincial (city) breed trial (recognition), with a total area of 261khm2. A large number of vegetables introduced excellent resources by the national breeding units are widely used to cultivate new varieties, access to major social and economic benefits.
