摘要： Hybrid rice breeding is mainly based on the advantages of male sterility and effective restorer lines. The strong restorer lines Minghui 63 and Minghui 86 and other related restorer lines were successfully bred and widely used in the 20th century. The approaches and technologies of restorer line breeding for hybrid rice are summarized in this paper. Breeding methods have been improved with pyramiding of restoring genes with genetic diversity, setting up a protocol for blast resistance, screening restorer lines, and combining characteristics of high yield, high grain quality, blast resistance, wide adaptability, and ideal plant type in different ecosystems. Thus, breeding efficiencies were promised. The new generation of restorer lines was much improved by integrating elite characteristics. Furthermore, the current status of the application of restorer lines for hybrid rice is discussed and ideas on hybrid rice development are proposed.
