    • TAXONOMY AND SPECIES DIVERSITY OF POTATO CROP WILD RELATIVES Expert consultation workshop on the use of crop wild relatives for pre-breeding in potato February, 2012 A. Salas, V. Quispe, O.

    • GEOGRAPHIC DISTRIBUTION OF THE POTATOWILDCULTIVATED DISTRIBUCION GEOGRAFICA DE LA PAPA
    • Geographic distribution of Solanum sectionPetota, wild. Most of the 187 wild potato species are rare and endemic species. They occur between 38 ° N and 41 ° S, with more species in the Southern Hemisphere. The highest species richness occurs in northern Argentina, central Bolivia, central Ecuador, central Mexico and Peru. Wild potatoes grow from sea level to 4400 m, but more often at altitudes of 2000 and 4000 m. La mayoría de las 187 especies de papas silvestres son raras y endémicas. Habitan entre 38 °N y 41 °S, con más especies en el hemisferio meridional. La mayor riqueza de especies ocurre al norte de Argentina, centro de Bolivia, centro del Ecuador, centro de México y Perú. Las papas silvestres crecen desde el nivel del mar hasta 4400 msnm, pero con mayor frecuencia entre altitudes de 2000 y 4000 msnm. Juarez H. CIP (2007)

    • DISTRIBUTION OF THE DIVERSITY OF NATIVE POTATOES Geographically, the total cropping area of native cultivated potatoes is very large, stretching from Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina to Chile. Within this large area local farmers grow the crop that has different chromosome numbers (2x, 3x, 4x y 5x). However, the highest concentration of these polyploids and morphological forms occur in the Lake Titicaca area (Meseta del Collao) in northern Bolivia and southern Peru. This area contains the highest concentration of landraces and is considered the primary center of origin. Geográficamente, el área total de siembra de las papas cultivadas nativas es muy grande, se extiende Especies de desde Venezuela, Colombia, Ecuador, Perú, Bolivia, Papas nativas Argentina y Chile. Dentro de esta gran área crecen poblaciones locales de este cultivo que tienen diferentes número cromosómicos (2x, 3x, 4x y 5x) . Sin embargo, la mayor concentración de estos citomorfismos y formas morfológicas se da en los terrenos lacustres del Lago Titicaca (Meseta del Collao) norte de Bolivia y sur del Perú. Aquí se encuentran más variedades de papa que en otras partes del mundo. Considerándose el centro de origen primario.

According to FAO, potato is the worlds fourth major food crops after wheat, maize and rice. La papa se produce en la actualidad en 143 países, y alimenta diariamente a cientos de millones de personas. De acuerdo a la (FAO), de los cultivos alimenticios principales del mundo la papa es el cuarto después del trigo, maíz y el arroz.
