Genetic and ampelographic identification of different grape varieties known as 'Tempranillo' in Rioja (Spain)
Spanish viticulture possessed great genetic resources which were in danger of extinction, but nowadays they are being recovered and studied through several research programmes. During previous studies carried out in Rioja appellation (MARTÍNEZ DE TODA et al. 2004 ), 76 vine accessions were collected and planted in a germplasm bank in the farm of Rioja's Government, called "La Grajera". 'Tempranillo' is the red variety with higher number of hectares grown in the Iberican Peninsula, in Spain and in Rioja appellation. In the germplasm bank of "La Grajera" there are 14 accessions whose local name includes 'Tempranillo': 'Tempranillo', 'Tempranillo Blanco', 'Tempranillo Royo', 'Tempranillo del Barón' and 'Tempranillo Temprano'. The objective of this work is to identify all these accessions containing the word 'Tempranillo' in the local name. ; Peer Reviewed
