Abstract: Application of molecular marker provided new technology for japonica hybrid rice breeding. It can greatly improved breeding efficiency that combined with molecular marker and traditional breeding technology. This paper summarized the research and application status of molecular marker in japonica hybrid rice breeding, including analysis of genetic diversity, construction of core germplasm, molecular marker-assisted selection in breeding, heterosis prediction and establishment of DNA fingerprintmap. The main problems for application of molecular markers in japonica hybrid rice breeding were discussed, and the application prospect was also developed.
