Abstract

Abstract: Genetic diversity on 34 Fenghuang-Dancong tea plants were evaluated by AFLP fingerprinting using 5 primer combinations. The 5 primer combinations generated 438 bands and 87.6 bands were amplified by each primer pair on average, 348 bands(79.3%) polymorphic AFLP markers were detected, The result indicated that the genetic distance(GD) based on AFLP data by using DPS2000 was significant. The varience range of GD among the 34 Fenghuang-Dancong was 0.13~0.49. The GD(0.49) is highest between Zimaohuangzhixiang and Funanmilan and between Baiyedancong and Tongtianxiang, however, the GD(0.13) between Da-ansongcha and Zongsuojia is low. The dendrogram indicated that the genetic of 34 Fenghuang-Dancong germplasms have no certain relation with the aroma type.
