[en] The province of Huesca (Spain) is a traditional area for growing grapevines. There are archaeological evidences of their cultivation at least since the second century B.C. Nevertheless, in the last years the varietal diversity is markedly decreasing due to the rooting out of old plantations that are replaced with new broadly known varieties, since the market demands a certain standardization of the wine producing varieties. The objective of this study is to examine and characterise the existing varieties in the province of Huesca, mainly in vineyards planted before 1960. A total of 47 accessions were collected in 14 plots from 11 municipalities. Moreover 36 accessions from the region, planted at the Movera grapevine germplasm bank (Movera collection), located at Zaragoza (Spain) were included in the study. Ampelographic characterisation was carried out with 50 OIV descriptors for two consecutive years. Molecular characterisation was made with the following microsatellites: VVS2, VVMD5, VVMD7, VVMD27, VrZAG62 and VrZAG79. Ampelographic results were compared by cluster analysis. Most of the accessions were identified, being considered as new varieties: two white, Carrillera and Moscatel, and six red or black: Macicillo, Bomogastro, Angelina, Terrer, Parraleta Roja and Garnacha Gorda. Several new synonymies were detected, as Miguel for Vitadillo or Parrel for Trepat. Seven accessions remained unidentified. Out of the studied Vitis vinifera varieties, 23 were considered as endangered, indicating the valuable patrimony of the zone to be preserved.

[es] La provincia de Huesca (Espa&ntilde;a) ha sido un lugar tradicional de cultivo de vid. Existe evidencia arqueol&oacute;gica de la existencia de dicho cultivo desde el siglo II a.C. Sin embargo, en las &uacute;ltimas d&eacute;cadas la diversidad varietal est&aacute; disminuyendo marcadamente debido al arranque de antiguas plantaciones que est&aacute;n siendo reemplazadas con nuevas variedades ampliamente conocidas, ya que el mercado demanda una cierta estandarizaci&oacute;n de las variedades productoras de vino. El objetivo de este estudio es caracterizar e identificar las variedades existentes en la provincia de Huesca, principalmente en vi&ntilde;edos plantados antes de 1960. Se muestrearon 47 accesiones de 14 parcelas en 11 municipios. Adem&aacute;s se incluyeron otras 36 accesiones de la provincia de Huesca que se encuentran en el banco de germoplasma de vid de Movera (colecci&oacute;n de Movera), situado en Zaragoza (Espa&ntilde;a). La caracterizaci&oacute;n ampelogr&aacute;fica se llev&oacute; a cabo con 50 descriptores durante dos a&ntilde;os consecutivos. La caracterizaci&oacute;n molecular se realiz&oacute; con los siguientes microsat&eacute;lites: VVS2, VVMD5, VVMD7, VVMD27, VrZAG62 y VrZAG79. Los resultados ampelogr&aacute;ficos se compararon mediante an&aacute;lisis de enjambres. Se identific&oacute; la mayor parte de las accesiones, detect&aacute;ndose las siguientes variedades nuevas: dos blancas, Carrillera y Moscatel, y seis rojas o negras, Macicillo, Bomogastro, Angelina, Terrer, Parraleta Roja y Garnacha Gorda. Se detectaron varias sinonimias nuevas, como Miguel para Vitadillo o Parrel para Trepat. Siete accesiones quedaron sin identificar. De las variedades de Vitis vinifera estudiadas, 23 se consideraron en peligro de extinci&oacute;n, lo que indica el valioso patrimonio de la zona que debe conservarse.
