Abstract: Tea is an important economic crop in China. Since 60s, tea breeding has been the focus of tea research. In order to offer new corn germplasms for tea breeding work and achieve a breakthrough in breeding work, widely development on tea polyploidy breeding research was carried out both at home and abroad. In this paper, the research progress of tea polyploidy breeding technology was summarized from the acquisition and identification two aspects. The study of polyploidy induction efficiency and the new inducer should be strengthened. It is pointed out that the chimera is a common problem in polyploidy breeding; The regeneration frequency and establishment of genetic transformation system of tea in vitro has great significance for the isolation of tea chimera and the establishment of polyploidy induction technology. In this paper the advantage in tea polyploidy breeding and developing directions are also discussed.
