- Abstract
Costus speciosus, an important medicinal plant species found in the Andaman and Nicobar Islands, was collected from 14 localities through recurrent survey. RAPD-PCR analysis involving 12 decamer random primers was used to assesses the quantum of genetic variation at genomic level. Four primers showed appreciable intra-species variation or molecular polymorphism at amplicon levels. Despite morphological identity, a great deal of polymorphism was observed among the accessions. UPGMA analysis showed ~35% variation in the collections, which is deemed to be useful in formulating sound conservation strategies for this precious medicinal plant species under the humid tropics of Bay Islands.
