Breeding of tea varieties refers to selecting and improving tea varieties to cultivate new varieties with high yield, high quality and strong stress resistance. The methods of tea variety breeding mainly include traditional breeding and molecular breeding.

Traditional breeding mainly adopts natural hybridization, artificial hybridization, selection and progeny test to select individuals with excellent traits, and finally selects bred varieties with excellent traits.

Molecular breeding is to use molecular biology and biotechnology to analyze and transform tea tree genes, so as to realize accurate improvement and breeding of tea tree characters.

How to maintain the traditional flavor and aroma of tea is also an important aspect of tea variety breeding, so it is necessary to carry out tests and research on taste evaluation and chemical analysis in breeding.
