Eight indigenous orchids were collected from different locations in the Andaman Islands. 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) forms a major cluster from all other species with a similarity of 67%, Both the Cymbidiums exhibited the highest similarity betvween them to about 77%. Pholidota imbricata exhibited higher similarity with Dendrobium secundatum than with other species of Dendrobium.
