Use RAPD Analysis to Classify Tea Trees in Yunnan

<正> RAPD assessment on genetic variations of 45 tea trees in Yunnan was carried out. Eight primers selected from 40 random primers were used to amplify 45 tea samples, and a total of 95 DNA bands were amplified, of which 90(94.7%)were polymorphism. The average number of DNA bands amplified by each primer was 11.5. Based on the results of UPGMA cluster analysis of 95 DNA bands amplified by 8 primers, all the tested materials could be classified into 7 groups including 5 complex groups and 2 simple groups, which was basically identical with morphological classification. In addition, there were some speciations in 2 simple groups.
