Abstract: With the rapid development of biotechnology, gene editing technology has become an important tool in the field of modern agricultural breeding. Especially in maize, a globally important food crop, the application of gene editing technology shows great potential and prospects. In this study, the recent progress and applications of gene editing technology in maize research are reviewed, with a focus on the latest achievements in maize genome editing by systems such as CRISPR/Cas. Firstly, the basic principles and types of gene editing technology are introduced, particularly the working mechanism of the CRISPR/Cas system and its application advantages in maize. Secondly, a detailed review of the research progress of gene editing technology in maize breeding is provided, covering various aspects from basic genome editing to complex multi-gene regulation, aiming at the improvement of key traits such as maize yield, quality, and stress resistance. Finally, the contributions of outstanding researchers in China and the existing issues of gene editing technology in maize breeding are discussed, along with an outlook on future development trends. With the continuous improvement and breakthroughs in gene editing technology, it will play an irreplaceable role in maize breeding, propelling maize research to new heights.
