Two new type rice restorer lines with 3-grain clustered type in top spikelet,Cu R3 Zi 10 and Cu R3 Zi 11,were bred by means of pedigree method,which were derived from restorer line R6030274 with the characteristics of stout stem,big spike and high grain density crossed with restorer lines Cu RH33 with long spikelet,much grains,3-grain clustered type in top spikelet.Their hybrid varieties,Shuang zi II you 10,Shuang zi II you 11,San zi guang liang you 10 and San zi guang liang you 11,by crossing Cu R3 Zi 10 and Cu R3 Zi 11 with II-32A and Guang zhan 63S,showed the good characteristics of stabile fertility,uniform plant population,big spike and much grains,high seed setting rate and high yield.
