Abstract We constructed a microsatellite‐enriched genomic library for Bactris gasipaes , an economically important, domesticated palm. We developed 18 polymorphic microsatellite markers, and found an average of seven alleles per locus in a sample of 14 individuals selected from a germplasm bank. Cross‐species amplification was evaluated in six other Bactris species. The loci detected will permit population studies and germplasm characterization, and can be used for genetic analyses in related species.
