Rice, a major food crop in China, contributes significantly to international food stability. Advances in rice genome sequencing, bioinformatics, and transgenic techniques have catalyzed Chinese researchers' discovery of novel genes that control rice yield. These breakthroughs in research also encompass the analysis of genetic regulatory networks and the establishment of a new framework for molecular design breeding, leading to numerous transformative findings in this field. In this review, some breakthroughs in rice yield traits and a series of achievements in molecular design breeding in China in recent years are presented; the identification and cloning of functional genes related to yield traits and the development of molecular markers of rice functional genes are summarized, with the intention of playing a reference role in the following molecular design breeding work and how to further improve rice yield.
水稻是中国的主要粮食作物，对国际粮食稳定做出了重大贡献。水稻基因组测序、生物信息学和转基因技术的进展推动了中国研究人员对控制水稻产量的新基因的发现。这些研究突破还包括遗传调控网络分析和分子设计育种新框架的建立，在该领域产生了众多变革性成果。本文综述了近年来中国在水稻产量性状方面的一些突破以及分子设计育种的一系列成果；总结了与产量性状相关的功能基因的鉴定与克隆以及水稻功能基因分子标记的开发，以期对后续分子设计育种工作及如何进一步提高水稻产量起到参考作用。
