(1) The seed selection is the selection of the natural variation produced by the peach seed breeding population and the selection of the excellent variety type. China's local varieties are all derived from seed selection, such as Feicheng Peach, Shenzhou Peach, Baihua, Fenghua Peach, etc. These varieties are often collectively referred to as a variety of varieties, which can be further subdivided into different types. (2) Bud mutations Bud mutations are genetic mutations that occur in the meristem cells of buds. Branches sprouted from mutant buds produce new variant traits. The method of selecting good buds and carrying out vegetative propagation to form new lines is called bud selection. Annong water honey is a budding variety with early growth of sand. (3) The crossbreeding crossbreeding peach breeding techniques include the determination of breeding objectives, the selection of crossbreeding parents, the acquisition of hybrid fruits, the cultivation of hybrid seedlings, the selection and selection of hybrid offspring, and the testing and demonstration of excellent lines. Validation and promotion of new varieties. The entire process of cultivating new varieties of peach generally takes about 10 years.
