Aggiornamento del Registro Nazionale delle Varietà di Vite - Principali caratteri dei cloni di recente omologazione

Abstract: Updating of the clone catalogue Planting a vineyard with multiplication material of good quality is a guarantee of duration and productiveness. Therefore the vine nursery sector has been engaged in spreading selected material by putting on the market clones which, besides being free from virus diseases and having specific agronomic features, are also suitable for the production of specific types of wines. This result is linked to the knowledge of the local ampelographic platforms which has permitted to identify many biotypes in the same population thus increasing the value of the intravarietal variability. Recently some clones of cultivars widely cultivated on the national territory were registered in the National Register of Grapevine Varieties, although they are concentrated only in some regions such as Carricante, Grillo, Nebbiolo, Rebo, Traminer or concentrated only in small places such as Albarola, Alionza, Barsaglina,Goldtraminer, Pignolo, Tazzelenghe, Trebbiano Modenese. New clones of international cultivars (Cannonau, Malbech, Sangiovese, Syrah, Tempranillo, Trebbiano Toscano) have been registered too thanks to their improving features: in fact they have smaller clusters and smaller berries but at the same time they assure a satisfactory production, they give wines with a better structure and therefore they are suitable for long ageing and they are more resistant to vine diseases than the original population. We hereby present the updated descriptions of the clones which recently entered the National Register thus enabling the potential users and the companies which work in the vine-growing and oenological sector to enlarge their knowledge on the clones attitudes. In each file, we can find the picture of the cluster, the description of the vegeto-productive characteristics, the organoleptic judgment on the wine and suggestions for the potential oenological use.
