| 摘 要： | [目的]为更好地在生产上利用新育成反向核不育水稻FHS。[方法]利用低能氮离子柬为诱变源对籼型品系99-02进行诱变处理，在其后代中筛选到育性特殊的突变材料FHS，该研究对其开花习、柱头外露率等特征特性进行观察。[结果]反向核不育水稻FHS在10：00～10：30有明显的开花高峰期，第2个开花高峰期为中午12：00；反向核不育水稻FHS单株开花期为8月12～25日，单穗开花为8月5～10日，与培矮64S相比，其开花较早、花时集中，有利于种子繁殖；FHS柱头外露率为85．8％，外露率较低，有利于繁殖制种纯度。[结论]反向核不育水稻FHS有较好的使用价值，且可以用作光温敏核不育水稻育性转换机理研究的对比材料。

| Abstract: | [Objective] The experiment aimed to use reverse genic sterile rice FHS better in practical production.[Method] The low energy nitrogen ion beam was taken as a mutation source to conduct mutagenic treatment for hsien rice 99-02 and the mutation FHS with special fertility was isolated from their offspring.The some characteristics such as flowering habit and stigma exsertion rate of FHS were observed in this experiment.[Result] The reverse genic sterile rice FHS had a obvious peak flowering stage from 10:00 to... |
