This paper explores the development of Breeding 2.0, which represents the transition from Breeding 1.0 (primitive selection) to Breeding 2.0 (conventional breeding). Breeding 2.0 is a scientifically driven breeding approach based on Mendel's laws of inheritance and quantitative genetics theory. One of its key features is the creation of variation populations and the application of phenotype selection to improve plant varieties. The emergence of Breeding 2.0 has shifted breeding practices from unconscious selection and empirical methods to a more scientific and conscious selection approach. By creating variation populations and employing phenotype selection, breeders are able to more accurately select and improve plant varieties, enhancing crop yield, quality, and resistance. Breeding 2.0 has had a lasting impact on plant breeding and agricultural development, laying the foundation for future advancements in breeding.
