Breeding method for new tea tree variety

Abstract

The invention provides a breeding method for a new tea tree variety. According to the breeding method, variety breeding is carried out for parents with local germplasm resources of Chun'an County, andparent bodies are selected according to high yield, high quality, strong stress resistance, the peculiarity and high whitened degree which serve as the breeding targets; a wild Jiukeng albino tea variety and a group albino tea variety are finally selected as the parent bodies for artificial field interbreeding, and breeding is carried out through early-stage pre-selection identification and systematic breeding; due to the influence of double-parent cell heredity, the characters of offspring obtained by interbreeding tend towards the characters of the wild Jiukeng albino tea variety, in orderto enable the effective characters controlled by plasmagene to be utilized so as to achieve more excellent characters of the wild variety, the parent bodies with the same ecological features, the samegeographic origin and different genetic relationships are selected at the same time, and due to the fact that the genetic bases of the parents are different, a new variety which surpasses the parentsand is high in adaptability can be more easily bred by the obtained new variety.

Description

technical field [0001] The invention relates to the technical field of mixed breeding of tea trees, in particular to a method for mixed breeding using wild Jiukeng species albino tea and group species of Jiukeng species albino tea as mother bodies. Background technique [0002] The "wild albino tea" species of Jiukeng has white tender buds and leaves, like platinum, named wild albino tea, which is rarely found. It is a tree type shrub type, with branches fully open, middle leaves, dark green leaves, and thicker leaves. , the new shoots are longer, the spring buds have a strong germination force, the quality of the tea is very good, the freshness of the buds and leaves is very good, the albino tea of ​​Jiukeng species is an excellent variety, the young buds are white jade in early spring, and the tea leaves are white in color in the late spring tea. As the temperature rises, the leaf color gradually turns green, and the spring buds germinate in late March. The tree type is sh...

Problems solved by technology

[0005] The purpose of the present invention is to provide a breeding method for a new variety of tea tree, which solves the problem of low yield, slow growth rate, low fruiting rate, underdeveloped root system, and low survival rate of cuttings in the wild albino tea tree of the Dove Keng species. The technical problems of pit-species albino tea with impure degree of albinism and unstable physiological properties
