Abstract： Maize is one of the most important food crops and plays a decisive role in the people's livelihood and national economy in China. Its sustained and stable production is of great strategic significance for ensuring food security and supply-side structural reform. Although traditional hybrid breeding technology has made a great contribution to increasing maize production, it can no longer satisfy the demand for a better life of current society. With the rapid development of modern biotechnology, molecular breeding has become an important direction and an inevitable choice for maize breeding, and the molecular module-based crop design technology, by combining multiple disciplines to achieve multi-module optimization and assembly at the whole genome level, will greatly promote maize breeding in China. Here, we provide an overview on the development of maize breeding technology and the significant achievements of molecular module-based technology in maize breeding recently. Finally, directions for maize breeding in future are also discussed.
