摘要
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。
Total 11410 accessions of exotic vegetable germplasm,belonging to 14 families,48 genera,and 72 species were introduced into China from 40 countries or regions from 1971 through 1996.More than 20 species were rare vegetable in China.Some of them were disease and pest resistant,male sterile,heat or cold tolerant materials.5345 accessions have been evaluated at different ecological regions.More than 40 varieties have been selected from these materials. Those varieties have been already extended in the production and got enormous economic benefits.A large amount of the elite genetic resources are being used for developing new varieties.
