摘要
杂交水稻良种繁育体系包括制种技术体系，三系原种生产体系和供种体系三个方面，文中概述这三方面的研究和进展。
Hybrid rice seed production system includes three aspects:technical system of hybrid rice seed-making,foundation seed production system of″three lines″,and seed-supplying system.The effectivecombination of conventional cultivation and special cultivation in rice is the main content of the technical sys-tem of hybrid rice seed-making.In foundation seed production system of″three lines,the seed productionprogram called,″three lines with seven blocks″has been established,and its main purpose is keeping the seedpurity.The main points of seed-supplying system are the consolidation and development of special seedproduction bases,and market adjustment in the process of seed circulation.
