Tea clone breeding
The breeding method of combining single plant breeding with asexual reproduction to produce new varieties was adopted. Tea varieties bred by clones are called tea clone varieties or tea clone varieties. It can reflect the heredity of the mother tree, can maintain the excellent characters of the improved tea varieties, the propagation speed is fast, the propagation cycle is short, and it can be propagated by cutting seedlings at the seedling stage, and the propagation coefficient is high. Since the successful popularization of tea short-spike cuttings, tea clone breeding is the breeding method of "single plant selection-cutting propagation". Breeding prescription
