摘　　要：[Objective] This study was to use reverse genic male sterile FHS better in field production. [Method] Low energy nitrogen ion beam was taken as a mutation source to conduct mutagenic treatment for indica rice 99-02 and the mutant FHS with special fertility that was isolated from their offspring. 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 an obvious peak flowering stage from 10:00 to 10:30, while the second peak flowering was from August 5 to August 10. Compared with PA64S, FHS flowered early and its flowering time was concentrated, showing that it is for seed propagation. The stigma exsertion rate of FHS was 85.8% and low exsertion rate was good for the purity of seed. [Conclusion] The reverse genic sterile rice FHS had good value in use, besides, it could also be used as comparison material for studying fertility alternation mechanism of photoperiod sensitive genic male sterile rice.[Objective] This study was to use reverse genic male sterile FHS better in field production.
