dc.description.abstractMusa acuminata Colla, the wild progenitor of banana, has a long evolutionary history intervened by human activity. Forty three accessions of M. acuminata ssp. burmannica, collected from 3 wildlife sanctuaries of Agastyamalai Biosphere Reserve of Western Ghats, India were studied for their genetic diversity and differentiation using random amplified polymorphic DNA (RAPD) markers. The results indicated a relatively high level of genetic diversity in Musa accessions at the species [Nei’s gene diversity (H)=0.47; Shannon information index (I)=0.66)] as well as population level (H=0.42; I=0.61). A relatively high degree of genetic differentiation was also observed among the populations (GST=0.30). Moreover, analysis of molecular variance (AMOVA) showed the existence of vast (81%) genetic variation within the populations. The Mantel test revealed a significant correlation (Rxy=0.54; P<0.001) between the geographic distance and the genetic distance of these populations. The genetic variability among these accessions suggests that the management for the conservation of the genetic diversity in M. acuminata should aim at preserving each and every accession at Agastyamalai Biosphere Reserve. en_US
