Random amplified polymorphic DNA-based assessment of genetic variation in natural and cultivated allspice (Pimenta dioica (L.) Merr.) populations in Guatemala

The fruit of the allspice tree (Pimenta dioica (L.) Merr.) is a valuable non-timber forest product traded for its flavour, oils and secondary metabolites. Intense selection pressure from traditional harvesting methods has favoured low-height, high-yield phenotypes, potentially impacting genetic diversity. Although phen...
