Shan tea is popular in the Northern mountainous region of Vietnam, this tea which known to grow more than 100 years ago, thus it was called the old tea. Shan tea is valuable gene source in Vietnam. In order to preserve, exploit and expand this tea variety; specially for tea breeding, beside evaluation of morphological and agnominal traits, the application of molecular techniques is to play very important role. Therefore, in this study, RAPD markers have been used to analyze genetics diversity of 39 Shan tea samples with 20 primers. The result indicated that 16 primers showing clearly polymorphism between samples, 9 main groups were identified with highly genetic similarity, correlation coefficient is ranging 0.61 - 0.94. The result also indicated that the tea samples collected in the same region which were mainly clustered in the same correlation group.
