Through a variety of technology integration, molecular design breeding to breeding process simulation and optimization of multiple variables, thus put forward genetic types and produce the most suitable breeding goal genotype selection strategy of parent and offspring，and also can improving the efficiency of breeding and breeding success rate and Realize from the traditional experience breeding to the conversion of the orientation, ensure the accurate and from experience to fixed-point breeding. Meanwhile with other auxiliary molecular technology increasingly sophisticated at the same time, the rapid development of biology and informatics, biological IT software development, such as molecular design breeding is becoming the main method of rice breeding. This paper reviews recent development situation of rice molecular design breeding in our country, and combining with the domestic and foreign research situation of molecular design breeding in the future for further prospects, finally put forward our country rice molecula
