Abstract:

Total DNA from green tea was extracted through improved CTAB method.Results indicated that the high quality DNA from green tea could be obtained with new method, the DNA yield ranged from 101– 498 μg/g tea sample for various green tea samples,and the average yield was 249 μg/g tea sample. The identification of green tea with ISSR suggested that different green tea produces could be effectively differentiated,which provided the reference for further research on molecular identification of green tea.
