[Objective]The paper aimed to study the restoring ability and restoring gene mapping of normal indica red rice Ruby.[Method] The pollen fertility of the(Zhenshan 97A、D62A、G46A and D702A)/Ruby F1,and F2,BC1 generations were examined,and mapping the restoring gene with SSLP.[Result] The results showed that the restoring gene was located on the chromosome 7,7.4 cM from RM182,which was not the same as the usually fertility-restoring gene family location on the chromosome 10,so it was a special restoring gene.[C...
