In this paper,the research status and development trend of rice quality at home and abroad were reviewed,the genetic basis of rice quality formation,regulatory molecular mechanisms and strategies for optimizing rice quality were summarized,and the correlation between rice quality and related genes such as starch,protein,lipid,aroma and color was revealed.Two specific countermeasures to improve rice quality,gene editing technology and molecular marker-assisted technology,were described.The challenges in rice quality research,such as imbalance between rice quality and yield,difficulty in transforming and popularizing rice quality improvement technology,regional adaptability of rice in breeding process,high breeding cost and long breeding cycle,and consumer acceptance of improved rice,were pointed out.Countermeasures were put forward from the aspects of multi-party cooperation and resource sharing,strengthening basic research and innovative technology,efficient screening and evaluation methods,considering diversified needs,and promoting the integration of industry-university-research and technology transformation,so as to provide theoretical guidance for optimizing rice quality and cultivating high-quality rice varieties.
