Abstract China has a long history of tea plant breeding and a solid research foundation as the origin
of tea plants and a major tea producing country in the world.Clonal tea cultivars and vegetative propagation
techniques first appeared in China，and China has bred the largest number of tea cultivars in the world.The
researches on the genetics and breeding of tea plants in China have accelerated after the reform and opening
up.After entering the 21st century，it has achieved good results in many fields including the number and di⁃
versity of cultivars bred，breeding technology，and basic theory of breeding，especially in the fields of tea
whole genome sequencing and assembly，functional genomics and other fields，leading the world and strong⁃
ly supporting the high-quality development of tea industry in China. This article reviews the history and
achievements of researches on the genetics and breeding of tea plants in China，and sorts out the problems
existing in the genetic rules of the main characters of tea plants，breeding techniques，and innovation of
breakthrough varieties.In view of these problems，some priorities of researches on the innovation of basic
theories of genetics and breeding，breeding technology and cultivar in the future are put forward.It will pro⁃
vide valuable reference for further studies on the genetics and breeding of tea plants.
