Abstract

Prior to 1996, worldwide holdings of germplasm of wild potatoes from Costa Rica amounted to just two collections; this country therefore formed a priority for collecting. We mapped all localities of wild potatoes from herbarium specimen data from Costa Rica and collected throughout the country. We made 13 collections, 10 of these with botanical seeds. These collections considerably extend the numbers of accessions and geographic range of the germplasm available from Costa Rica. The taxonomic identity of the species of wild potatoes (Solanum sect. Petota) in Costa Rica was previously unresolved. Our fieldwork supports the concept that Costa Rican wild potatoes belong to a single species,S. longiconicum.

Resumen

Antes de 1996, las colecciones de germoplasma de papas silvestres de Costa Rica eran sólo dos en todo el mundo; este país, por lo tanto, estableció como una prioridad formar su colección. Con ese fin, asociamos todas las localidades de papas silvestres, tomándolas de una base de datos de muestras de herbarios de Costa Rica y las colectamos a lo largo y ancho del país. Formamos 13 colecciones, 10 de ellas con semilla botánica. Esas colecciones extendieron considerable-mente el número de accesiones y rangos geográficos del germoplasma disponible de Costa Rica. La identidad taxonómica de las especies de papa silvestre (Solatium sect.Petota) de Costa Rica no había sido resuelta previamente. Nuestros trabajos de campo apoyan el concepto de que las papas silvestres de Costa Rica pertenecen a la especie singularS. longiconicum.
