Potato systematics and germplasm collecting, 1989–2000

Article

Abstract

This paper reviews the systematics of wild potatoes over the past 11 years, in reference to the latest comprehensive taxonomic treatment by Hawkes (1990. The potato: evolution, biodiversity and genetic resources. Belhaven Press, Washington, D.C.). Included here is information on monographs and floras, new germplasm collections made since 1988 compared to total potato distributional data, new taxonomic changes (including synonymy and new species descriptions), ingroup and outgroup relationships, intraspecific studies, diversity studies, and fingerprinting. In addition, data supporting taxonomic changes and phylogeny from ploidy levels, Endosperm Balance Numbers, and morphological studies of taxonomically important characters are reviewed. A revised list of 206 species is presented (from 232 in Hawkes) that incorporates recent synonymy of names, recognition of new names, and new species descriptions. New germplasm collections of 58 potato taxa were collected that did not occur in genebanks before 1988.

Resumen

En este articulo se resume el tratamiento sistematico de las papas silvestres durante los pasados 11 anos, en referencia al mas reciente tratado taxonomico deHawkes (1990. The potato: evolution, biodiversity and genetic resources. Belhaven Press, Washington, D.C.) Aquí se incluye información sobre monografías, nuevas colecciones de germoplasma hechas desde 1988 y comparadas con la distribución geográfica completa de papas silvestres, nuevos cambios taxónomicos (incluidas la descripción de sinónimas y de nuevas especies), parentesco filogenético dentro y fuera del grupo, estudios intraespecíficos, estudios diversos y tipificacion del ADN. Adicionalmente, se revisan los datos que sustentan los cambios taxonómicos y en el parentesco filogenético: niveles de ploidia, Balance Numérico de Endosperma y estudios morfológicos de caracteres taxonómicamente importantes. Se presenta una lista revisada de 206 especies (de 232 de Hawkes) que incorpora la reciente sinonimia de nombres, el reconocimiento de nuevos nombres y la descripción de nuevas especies. Se colectaron 58 taxa de papa que no se encontraban en los bancos genéticos antes de 1988.
