DISEGNA, Edgardo; FERRARI, Virginia  e  CONIBERTI, Andrés. Comparative Study of Commercial Clones of Tannat (Vitis vinifera L.) in Southern Uruguay. Agrociencia Uruguay [online]. 2017, vol.21, n.1, pp.33-42. ISSN 1510-0839.

Tannat is the main red wine variety cultivated in Uruguay for the production of wines for the domestic market as well as for export. In a process of reconversion of old virus infected plantations, clones selected in France began to be introduced in the 70´s. Clone 398 was the most adopted, without previous experience of its behavior in the country. In order to compare qualitative and quantitative performance, eight French Tannat ENTAV-INRA clones 398, 399, 472, 474, 475, 717, 794 and 944 were planted, fifteen plants per plot, in a randomized block design with eight replicates. The trial conducted on VSP trellis, with long pruning, and on rootstock SO4, was evaluated from 2005 to 2010. Ten plants per plot were thinned before veraison, and five remained with all their production. Yield, weight, and number of clusters per plant were evaluated, along with qualitative parameters of grapes and wines. Descriptive sensorial analyzes were carried out annually on wines by specialized panelists. Clones 398, 399 and 475 were more productive, showing significant differences with 474. Clones 474 and 717 had the best grape and wine quality independently of crop load. Their grapes had the highest contents of soluble solids and total and easily removable anthocyanins. The wines of these clones, along with 398, had the most fruity aromas, structure, and minor astringency. This suggests that both clones should be considered for future plantations for high quality wines under the agro-climatic conditions of Uruguay.
