Key Points and Practical Methods of Tea Plant Breeding Techniques Explained

Growing Techniques 0 views
In conventional tea plant breeding, single-plant selection and crossbreeding are mainly used. More than 90% of new tea plant varieties at home and abroad have been developed using these two methods. Single-plant selection uses naturally mutated material, that is, selecting superior individual plants from existing tea plant populations, then expanding their numbers through propagation while maintaining their superior traits. Crossbreeding uses gene recombination and interaction, making it possible for hybrid offspring to show combined superior traits of the parents or types superior to the parents. ① Correctly select parents; ② Master crossbreeding techniques; ③ Strengthen management after pollination.

Radiation breeding: the suitable dose for gamma ray irradiation of tea plants is: seeds 5-7 kiloroentgens, seedlings 4-6 kiloroentgens, cuttings 0.5-1 kiloroentgens.
