Abstract: The genetic diversity and relationship of 30 Wuyi rock tea germplasms were analyzed by Sequence-related amplified polymorphism (SRAP) markers. Forty three pairs of primers selected from 88 pairs of candidate SRAP primers produced 385 amplified fragments. Among them, 236 were polymorphic, accounting for 61.30% of the total fragments. The results showed that there was distinct genetic diversity within Wuyi rock tea germplasms. The genetic distance ranged from 0.31 to 0.98 with an average of 0.63. Thirty Wuyi rock tea germplasms were classified as three categories basing on the UPGMA cluster analysis. This study was of great significance for genetic research, breeding and resource protection of Wuyi rock tea.
