摘　　要：于2012-2013年利用自然冷水源这一得天独厚的条件,对2个遗传背景完全相同的同一温敏型两用籼型核不育系水稻进行不同水温处理;利用2个处理群体抽穗时间差,通过育性镜检等,实现核心种子的生产。研究了奥龙1S在自然冷水源条件下的提纯繁殖技术。Using the dual-purpose thermo-sensitive genic male sterile lines with the same genetic background as materials, the treatment of different temperature, two treatment groups at heading time difference and fertility micro- scope technology were set in the experiment to achieve the core of seed production. The purification and propagation technology of AoLong 1 s was studied under natural condition of cooling water resource.
