Резюме: Comparative study of 4 clones of Cabernet Sauvignon variety – 3/21, 7/14, 8/24 and ILV 1/11 was carried out at the Institute of Viticulture and Enology during the period 1998 – 2003 according to the approved methodology for clonal selection in the country. The studied clones surpassed the variety population in yield indicators (average mass per cluster and average yield per vine). They were characterized by intense sugar accumulation; as a result the sugars content was similar or slightly higher than that of the variety population. While the grapes retain good acidity higher levels had been reported in 7/14 and ILV 1/11 clones. As a result of the comparative study it was distinguished and approved by the Executive Agency Plant Variety Testing, Approbation and Seed Control 1 clone ILV 1/11 (certifcate No. 10974/31.01.2012) and 1 candidate-clone Cabernet Sauvignon 7/14 clone.
