美国自建国以来,作为农业振兴的基础,积极开展了从世界各国引进植物遗传资源的工作。美国遗传资源的引进、保存、管理体系是由国立和州立试验研究机构组成的组织网进行的,其工作方针由委员协商决定。该组织网的业务包括各种遗传资源的引进、保存、评价和提供等。已保存的品种和系统数为:国立种子贮存研究所约17万份,农业部农业研究中心约7万份,总数超过34万份。 Since the founding of the United States, as the basis for the revitalization of agriculture, the United States has actively carried out the work of introducing plant genetic resources from all countries in the world. The introduction, preservation and management system of American genetic resources is carried out by a network of state and state experimental research institutes whose working principles are decided upon by members. The network’s operations include the introduction, preservation, evaluation and provision of various genetic resources. The number of varieties and systems preserved is about 170,000 from the National Seed Storage Institute and about 70,000 from the Agricultural Research Center of the Ministry of Agriculture, with a total of more than 340,000 copies.
