Abstract

Betula alnoides is an ecologically and economically important species in the tropics and warm subtropics. Nineteen polymorphic microsatellite markers were isolated from this species, which displayed three to 12 alleles per locus. The observed heterozygosities ranged from 0.100 to 0.905, and the expected heterozygosities from 0.510 to 0.893. These markers would be useful tools in genetic resource assessment, molecular marker-assistant breeding, parentage analysis and genetic diversity studies for this species.
