中文摘要：

Long-term fertility cycle,low self-compatibility and short flowering period limited the tea breeding by conventional method.It is necessary to apply biotechnology,especially genetic transformation method,to obtain new mutants and to accelerate tea breeding.This paper reviews the status and progress in genetic transformation and related influencing factors.It has been noticed that tea genetic transformation has advantages in getting useful target mutants.The genetic transformation by Agrobacterium-mediated and gene gun methods are usually used.However,further research should be focused on improvement of plant regeneration.
