搞好原种生产是为农业生产提供优良种子的关键,因此,历来为国内外种子生产者所重视,并且在长期实践中创造了一些原种的生产方法。用原原种生产原种,在国外是被普遍运用的,而且绝大多数发达国家原种生产途径也仅此一种。在法国,原始材料、原种、基础种均属育种家的种子,并由育种者负责生产;而合格种子是由基础种子或原种直接繁殖的种子。墨西哥规定原原种由育种家或品种改良者控制,是生产基础种(原种)的来源。意大利规定基础种由育种家或育种单位直接生产,也可 Therefore, it has always been valued by both domestic and foreign seed producers and some original production methods have been created in long-term practice. The original species produced by the original species, is widely used abroad, and the vast majority of developed countries, the original species production is also only one. In France, the original material, the original species and the basic species belong to the breeder’s seed, and the breeder is responsible for the production; the qualified seed is the seed directly bred from the basic seed or the original species. Mexico provides that the original species is controlled by the breeder or breed innovator and is the source of the base species (original breed) produced. The Italian law stipulates that the basic species should be directly produced by breeders or breeding units
