Genetic diversity analysis among the Indigenous orchids of Bay of Islands using RAPD markers

Eight indigenous Orchids of Andaman and Nicobar Islands were collected from different location of the Andaman Islands. All the accessions were fingerprinted using 80 random amplified polymorphic DNA (RAPD) markers. Among the 80 primers, 40 showed amplification and a Similarity coefficients were calculated based on 400 selected bands and UPGMA clustering analysis. The result showed that the green orchid Eulophia andamensis (Pretty Green Bay) formed a major cluster from all other species with a similarity of 67%, Both the Cymbidiums exhibited the highest similarity between them to about 77%. Pholoidata impricata exhibited higher similarity with Dendrobium secundatum than the other species of the Dendrobium.
