Abstract

Based on AFLP method, AFLP figure were obtained in Guangdong tea plants. In this study, totally 365 bands were amplified by 5 pairs of primes and 73 bands were amplified by each primer pair on average, a total of 338 (92.6%) polymorphic AFLP markers were detected. The results indicated that the genetic distance (GD) based on AFLP data by using DPS 2000 was significant. The GD(0.5) is highest between Guibeidaye and Fenghuangshuixian, but the GD(0.12752) between Qingliangshan tea and Qingyuanbijia tea is low. This indicated that the Guangdong tea plant has a high genetic diversity.
