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 10:30,while the second peak flowering stage was at 12:00.The single plant flowering of reverse genic sterile rice FHS was from August 12 to August 25 and the single panicle flowering was from August 5 to August 10.Compared with PA64S,FHS flowered early and flowering time was concentrated,so it was good 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 also could be used as comparison material for studying fertility alternation mechanism of photoperiod sensitive genic male sterile rice.
