P-69 ‘Ribolla Gialla’ from north eastern Italy, ‘Rebula’ from northern Balkans and ‘Robola’ from Ionian islands: do they belong to the same population variety or are they genetically different? S.

Once part of the Venetian Republic, Friuli Venezia Giulia has been for long time an important step along the Mediterranean spice route from the Byzantine Empire to the trading centre of Venice. During the Middle Ages, travelers passing through this area are supposed to have brought grapevines from Balkans and Anatolia. Referring to historical information and reports Ribolla has been the leading quality wine used as a representative sign to honor famous figures of the ages. Known in Friuli since Roman Empire, for some authors, Ribolla would correspond to the Roman famous ‘Avola’ wine. Others believe that the Roman ‘Punicinum’ used Ribolla as its base wine. After the splendors and reputation gained by Ribolla wines in the past centuries, the beginning of the 1900s marked a difficult period for the wine, with a very modest reputation. And, in the ‘60s of the past Century the interest in the cultivation of Ribolla variety decreased, in the Italian region, leaving place for the cultivation of Tocai Friulano, Pinot Bianco and Grigio, Sauvignon, Traminer and Riesling. Despite the historical documents reporting the longstanding tradition of Ribolla cultivation and winemaking in Friuli- Venezia Giulia the origin of this variety is still questionable. The neighbor Regions Slovenia and Dalmatia have under cultivation a white berried wine-grape variety called Rebula, and in Greece (in the Ionic islands of Kefalonia) we have white wines produced with a variety named Robola. The aim of this work is to study the genetic structure of these 3 groups of white varieties and verify the existence of genetic relationships linking these accessions sharing the same name. For this purpose 20 SSR loci were tested to fingerprint 30 Ribolla-Rebula-Robola accessions uniformly distributed in the 4 areas of cultivation. Data obtained proved the existence of some synonym accessions and relationships between Ribolla-Rebula and Robola accessions. Basing on these results, indigenous varieties belonging to the same area of cultivation of the Ribolla- 149 
Rebula-Robola group were genotyped at the same SSR loci and some interesting results were obtained, helping to develop hypothesis about the place of origin of this group. 150
