| 摘 要： | 通过对两系杂交水稻两优航2号亲本（航2号与SE21S）特性及开花习性观察，结果表明：SE21S在福建沙县稳定的不育期较长，从7月至9月上旬具有稳定的不育期，在此时期进行制种安全可靠。两亲本的全生育期比较长，制种过程容易攻好苗架；且两亲本的播始历期非常接近，几乎没有播差期，花期容易相遇，两者抽穗高峰期花时相遇较吻合，是一个易制种获高产、稳产的新组合。

| Abstract: | In this paper,the characteristics and flowering habits of SE21S and Hang 2(the female parent and male parent of Liangyouhang 2) were investigated.The results showed that: SE21S had relatively long and stable sterility period from July to the first ten days of September in Saxian county of Fujian province.And its fertility was also safe and reliable.The two parents had quite a long whole growth period which was easier to reached a good seedling quality during seed production of hybrid rice.The duration from ... |
