良种繁育的任务一是加速繁殖和推广审定的新品种,使新品种尽快地应用于生产,替换与生产不适应的老品种;二是保持现有品种的优良种性,即对生产应用的良种进行提纯复壮,以提高其丰产性和优良品质。优良品种的推广应用是靠良种繁育体系进行的,《中华人民共和国种子法》(以下简称《种子法》)颁布实施前的良种繁育体系,对于优良品种的选育、推广以及保障农业生产,做出过重要贡献,但已不适应新形势下种子工作的要求,如何在新的形势下做好良种繁育体系建设工作,值得研究探讨。
The first task of breeding is to speed up the propagation and promotion of validated new varieties so that the new varieties can be quickly applied to the production, replacement and production of unsuitable old varieties. Second, to maintain the superior varieties of existing varieties, that is, the production and application of improved varieties Purification and rejuvenation to enhance its high yield and good quality. The popularization and application of fine varieties are carried out on the basis of improved seed breeding system. The “Seed Law of the People’s Republic of China” (hereinafter referred to as the “Seed Law”) promulgates the fine seed multiplication system before implementation, and selects and promotes fine varieties and agricultural production Have made important contributions but have not met the requirements of seed work in the new situation and how to do a good job of breeding and breeding system under the new situation is worth studying and discussing.
