Abstract: The genetic diversity and relationship of 35 germplasm resources (24 cultivated Dendrobium officinale, 9 Dendrobium species and 2 adulterants) were analyzed by SRAP markers. Ten SRAP primers were screened for the SRAP-PCR reaction, and 91 polymorphic bands were detected, and the polymorphic percentage was 98.9%. The SRAP results indicated the genetic diversity of cultivated D. officinale from different areas was rich. UPGMA analysis showed the 35 germplasm resources divided into 8 groups, 24 cultivated D. officinale were in one group, and separated from other Dendrobium species and adulterants. It also showed that unknown hybrid was a cross between D. officinale and D. guangxiense.
