This study further discusses the potential role and development direction of GWAS in rice breeding, especially its application prospects in precision breeding, multi-trait improvement, and adaptation to climate change. The importance of further understanding the rice genome, including studies of non-coding regions and epigenetic modifications, and the role of these studies in promoting the development of rice breeding technology are also discussed. In addition, this study also analyzed the challenges and opportunities facing rice genetic breeding, and pointed out that combining modern genetics technology, especially GWAS and gene editing technology, can effectively meet the challenges of improving disease resistance and meeting global food demand. Through GWAS analysis, researchers can accurately identify key genetic markers and genes related to rice yield and quality, providing a scientific basis for the cultivation of high-yield and high-quality rice varieties. Keywords Genome-wide association studies (GWAS); Rice breeding; Yield improvement; Quality improvement; Genetic markers 1 Introduction Rice (Oryza sativa L.) is one of the major global food crops, providing a staple food for most of the world's population. As the population grows and living standards improve, the demand for rice yield and quality continues to increase. However, traditional breeding methods have been unable to meet the growing demand. Therefore, it is particularly important to find new breeding methods and strategies to improve rice yield and quality. GWAS is a method to explore the relationship between genes and traits by comparing large-scale genotypic and phenotypic data. With the continuous development and cost reduction of sequencing technology, the application of GWAS in the agricultural field has received widespread attention and application. Especially in the field of crop genetics, GWAS has become an important tool for research, providing a new way to analyze the genetic basis of complex traits. In the field of rice, GWAS has successfully revealed many genes related to yield and quality. By analyzing large-scale rice germplasm resources and phenotypic data, researchers have identified many genes that have important effects on rice yield, resistance, and quality. The discovery of these genes provides new genetic resources and theoretical basis for rice breeding, helps to speed up the breeding process and improve breeding efficiency. This study aims to review the research progress of genome-wide association analysis (GWAS) in revealing genes related to rice yield and quality. This study will introduce the importance of rice yield and quality and the limitations of traditional breeding methods in meeting the needs. The basic principles and application status of GWAS in the agricultural field were further introduced in detail, especially its application in rice genetic breeding (Fang et al., 2017). The existing research results, including published GWAS articles and discovered genes related to yield and quality, will be used to predict the potential role and future development direction of GWAS in rice genetic breeding. Through research and analysis, we will comprehensively understand the application progress of GWAS in rice genetic breeding, provide reference and inspiration for future research, and also provide new ideas and methods for improving rice yield and quality.
