[ES] La judía común (Phaseolus vulgaris L.) es la leguminosa de grano más relevante para el consumo humano directo en escala global. Las colecciones de germoplasma de judía actuales muestran una amplia variación de fenotipos, aunque en muchos países las variedades locales están siendo reemplazados por cultivares de élite, concentrando la producción agraria en un número cada vez más reducido de cultivares con la consecuente erosión genética o pérdida de biodiversidad. Este cultivo se ha extendido por todos los continentes durante los últimos siglos, lo que ha dado lugar a una compleja estructura genética fuera de sus áreas de origen y domesticación (Mesoamérica y Sudamérica). Diversas evidencias indican que el germoplasma europeo contiene una diversidad adicional mayor de la esperada especialmente en el Sur de Europa, y particularmente en la Península Ibérica, dónde fue introducida a comienzos del siglo XVI, y que ha sido documentada como un centro de domesticación secundaria de la especie. La integración de datos ómicos en las bases de datos de documentación del germoplasma de judía y su combinación con datos genéticos, fenotípicos y agro-ecológicos está abriendo una nueva era para la valorización y el uso eficiente de los recursos genéticos de la judía común como la principal leguminosa de grano para consumo humano en Europa y globalmente.
[EN] The common bean (Phaseolus vulgaris L.) is the most important grain legume for direct human consumption on a global scale. Current bean germplasm collections show a wide variation of phenotypes, although genetic erosion is gradually affecting this species as in many countries local traditional varieties are being replaced by elite cultivars. This crop has spread to every continent over the past few centuries, which has resulted in a complex genetic structure of bean germplasm outside its areas of origin and domestication (South and Central America). Some evidence indicates that this germplasm is more complex than previously thought and contains additional, as yet unexplored, diversity. This is especially the case in southern Europe, particularly in the Iberian Peninsula, where it was introduced in the early sixteenth century and has been documented as a secondary focus of domestication of the species. The integration of omic data into bean germplasm documentation databases and its combination with genotypic, phenotypic and agro-ecological data is opening a new era for the enhancement and efficient use of common bean genetic resources as the main grain legume in Europe and worldwide.
