A cross-breeding method of a new variety of tea tree

Abstract

The invention discloses a hybridize breeding method for a new variety of tea tree, and belongs to the field of plant hybridize breeding. According to breeding objectives of high yields, good quality, high stress resistance and extra-early sprouting, field artificial hybridization is performed by adopting 'hungjinju' as a female parent (female) and introducing 'Anji white tea' as a male parent (male). The 'hungjinju' is a rare tea tree resource variety in Jiangxi, and is early-sprouting, high in sprout generating capability, high in growth speed, well-developed in root system, medium in fruiting rate, high in yield, high in cold resistance, and high in of short sprout cuttage survival rate. The 'Anji white tea' is a unique, different and excellent variety, is high in amino acid contents, unique in quality and fresh and mellow in taste, but is low in fruiting rate and medium in yield. By hybridization, single plant selection, vegetative propagation, variety comparison and zone testing, a new tea tree hybrid variety which is extra-early in sprouting, strong in shoot tenderness-keeping ability, obvious in three-dimensional sprouting, vigorous in growth, high in stress resistance, high in adaptability, high in yield and good in quality is bred. The new variety has excellent botanical characteristics of the female parent, integrates excellent characteristics of the female parent and the male parent, is obvious in hybrid advantages, meets market expectation, and has good development potential and practical popularization value.

Description

technical field [0001] The invention relates to the field of plant cross-breeding, in particular to a cross-breeding method in which "Radiant Chrysanthemum" is the female parent (♀) and "Anji White Tea" is the male parent (♂). Background technique [0002] Breeding and popularizing improved tea tree varieties is an economical and effective technical measure to increase tea yield and improve tea quality. Hybrid breeding is the main way to cultivate new varieties of tea trees. Sexual hybrid breeding uses the principle of gene recombination and heterosis to cultivate comprehensive and excellent traits with parents. And the quality exceeds the parental phenomenon. Artificial cross-breeding is to select parents according to the needs of breeding objectives, and to use local germplasm resources as parents to breed varieties, which has the characteristics of strong adaptability and easy promotion; To make use of the effective traits controlled by cytoplasmic genes, local varietie...

AI Technical Summary

Problems solved by technology

[0004] Jiangxi is a large province of tea production. There are relatively rich germplasm resources of local characteristic tea trees, and the quality characteristics of group varieties are outstanding. However, the breeding of fine varieties of famous, special and high-quality tea trees is still relatively backward. There are restrictive factors such as late germination and low yield of group varieties. Excellent traits of group germplasm resources, breeding new tea varieties with high amino acid content, strong flower fragrance, strong adaptability, excellent resistance, and special early variety, vigorously develop local famous tea varieties, actively create brands, and promote famous teas to enter the market as soon as possible Creating better economic benefits is an important topic of tea tree breeding, and will definitely be favored by tea production
