两系杂交稻新组合两优688高产制种技术

High-yielding Seed Production Techniques for New Two-line Hybrid Rice Combination Liangyou 688

两优688是南平市农科所用福建省农科院水稻所选育的两系不育系SE21S和自选恢复系南恢688配组育成的两系杂交晚稻新组合,2009年通过福建省农作物品种审定,2010年通过国家农作物品种审定。介绍了两优688双亲特征特性,结合建阳、武夷山等地制种实践,总结了其高产制种技术。

Liangyou 688,a new two-line late-season hybrid rice combination,was developed by Nanping Institute of Agricultural Sciences,which was crossed with a two-line sterile line SE21S from Rice Research Institute of Fujian Academy of Agricultural Sciences and a restorer line Nanhui 688 from ourselves.This combination was released by Fujian province in 2009 and by the state in 2010,respectively.According to the characteristics of parents and the practice of seed production from various sites such as Jianyang and Wuyishan,the high-yielding seed production techniques of Liangyou 688 were summarized.
