Breeding 4.0 represents a breeding revolution in genetic information integration and editing, and is an important innovation in the field of plant breeding. By integrating genetic and genomic information, Breeding 4.0 introduces highly precise genotype selection and gene editing technologies to improve breeding efficiency and accuracy. This revolutionary breeding method helps accelerate the improvement and optimization of crop varieties to meet the growing agricultural demand and sustainable development challenges. The technology and methods of Breeding 4.0, including the development of genome prediction and selection, the application of high-throughput phenotype determination, and the application of artificial intelligence and machine learning in Breeding 4.0. The application and benefits of Breeding 4.0 are obvious, including examples and advantages of genetically modified breeding and gene editing breeding, as well as the contribution of Breeding 4.0 to sustainable agricultural development. However, Breeding 4.0 faces ethical, legal, and social considerations, as well as technical and methodological challenges. Undoubtedly, Breeding 4.0 is the forefront and future direction of contemporary breeding, providing a foundation for achieving higher-level breeding goals.
