Abstract: Seeds of a plant, supposedly a palm tree known popularly as peach palm (Bactris gasipaes), were seized by the Federal Police in the state of Pará, Brazil, without documentation of legal origin to authorize transportation and marketing in Brazil. They were alleged to be from the western part of Amazonas, Brazil, near the frontier with Peru and Colombia, justifying the lack of documentation. The species was confirmed to be peach palm. To determine the likely place of origin, a genetic analysis was performed to determine the relationship between the seized seeds and representative populations of peach palm from all of Amazonia, maintained in the Peach palm Core Collection, at the National Research Institute for Amazonia, using nine microsatellite loci. Reynolds’ coancestry analysis showed a strong relationship between the seeds and the Pampa Hermosa landrace, around Yurimaguas, Peru. The Structure program, used to infer the probability of an individual belonging to a given population, showed that most seeds grouped with populations close to Yurimaguas, Peru, corroborating the coancestry analysis. The Pampa Hermosa landrace is the main source of spineless peach palm seeds used in the Brazilian heart-of-palm agribusiness, which motivated the smugglers to attempt this biopiracy. © 2017 Elsevier B.V.
