Abstract: The genetic relationship of 36 tea cultivars grown in Sichuan was studied by RAPD technique.
Sixteen primers selected from 50 random p rimerswere used to amp lify 36 tea samples, and a total of 167 DNA
bandswere amplified, among which 158 (94.61% ) were polymorphic. Genetic distances between the culti
vars varied from 0.149 to 0.679. UPGMA cluster analysis of 167 bands amplified by 16 p rimers was made.
The result showed that 36 tea cultivars tested could be classified into 3 comp lex group s and 2 simp le group s. It
was found that there was a certain correlation between the results and the derivation of tea cultivars.
