Identification of autochthonous grapevine varieties in the germplasm collection at the ITA of 'Castilla y León' in Zamadueñas Station, Valladolid, Spain

Abstract

During the last decades a study of the grapevine collection located at the Zamadueñas Station of the Instituto Tecnológico Agrario de Castilla y León (ITACyL) was carried out. Recently, molecular markers have been used for varietal identification and detection of the possible synonymies in the collection. This work shows the results of that characterisation, as well as the detected synonymies and homonymies in the study. The maintenance of the existing plant material is recommended, particularly with reference to the varieties with a marked risk of extinction because they are not presently object of new plantations.
