通过杂交、辐射诱变、自然变异选择等手段培育出了Ｒ９─１、Ｒ１８３１、Ｒ１８７等有实用价值的粳型两系杂交稻恢复系，１９９２～１９９３年用Ｒ９─１、Ｒ１８７、Ｒ１８３等与粳型光敏核不育系Ｎ５０８８Ｓ、７００１Ｓ制种３３３．３ｈｍ￣２，示范１００００ｈｍ￣２左右，成为我省首批应用于生产的粳型两系法杂交组合。
The restorer lines of japonica two-line hybrid rice with practical value such as R9─1, R1831, R187 were cultivated by means of hybridization, radiation mutagenesis and natural mutation selection. From 1992 to 1993, R9─1, R187, R183, Japonica type photo-sensitive genic male sterile lines N5088S, 7001S seed 333.3hm ~ 2, demonstrating 10000hm ~ 2 or so, becoming the first batch of japonica two-line hybrid combinations used in the production.
