八十年代以来,我省在杂交稻种子生产体制上,一直坚持由地区统一进行供各县配套制种用的不育系种子生产,对提高不育系种子的产量和质量、加强杂交稻种子的计划生产、推动杂交稻发展都起着非常重要的作用。但近几年来,由于对地繁基地管理不力,不育系种子在社会上流失严重,致使出现了大面积自发制种,冲击了杂交稻种子计划市场,降低了种子质量给农业生产造成了极大危害,如何控制不育种子流失,遏制计划外制种,已成为种子工作者普遍关注的问题,
Since the 1980s, our province has always insisted on the uniform production of CMS seeds for all the counties in the system of hybrid rice seed production, which has the potential to improve the yield and quality of CMS seeds and enhance the hybrid rice seed Plan to promote the development of hybrid rice plays a very important role. However, due to the poor management of the Dafu base in recent years, the loss of seed in the sterile lines in society has led to the emergence of a large area of spontaneous seed production, which has hit the market of hybrid rice seed programs and reduced the quality of seeds to the extreme of agricultural production How to control the loss of sterile seeds and curb unplanned seed production has become a common concern of seed workers.
