In construction of Pingxiang Dominant Genic Male Sterile Rice(PDGMSR)sterile gene mapping population,we found some reported maintainer lines shown the fertility restoration ability.Thus,this study systemly analyzed the fertility separation of F1,F2 and F3 populations of the crosses between the PDGMSR and the reported maintainer lines.We observed that the progenies from sib-crosses between male-sterile plant and fertile plant of the PDGMSR were always segregated in a ratio of 1 male-sterile to 1 fertile.The ...
