AB  - Background: Three clones of Cabernet Franc (Nos. 02, 010 and 012) were selected in the last phase of clonal selection in Serbia. Wines made from each clone were assessed for quality parameters and taste during five consecutive vintages (2008-2012) and compared to the standard. The wine quality was determined based on the following parameters: alcohol, total extract, anthocyanins, tannins, pH, titratable acidity, volatile acidity, aldehydes, esters and reducing sugars, relative density, ash, colour, tonality, and tasting score. In the last year of the study, grapes and wines of Cabernet Franc clones and a standard were subjected to a chemical analysis of their phenolic composition, resveratrol and radical scavenging activity. In the last year of the study, grapes and wines of Cabernet Franc clones and a standard were subjected to a chemical analysis of their phenolic composition, resveratrol and radical scavenging activity. Methods: Chemical analyses of grapes and wines along with sensory and radical scavenging activity evaluations were done according to the standard procedures. Results: The wines of the clone No. 010 showed some superior properties compared to the other two clones and the standard; in five-year period the average concentration of anthocyanins (179 +/- 3.8 mg/L) and polyphenolics (1.85 +/- 0.02 g/L) was significantly higher than in wines of clones and the standard, (168-173 mg/L and 1.63-1.74 g/L for anthocyanins and phenolics, respectively). Furthermore, the same clone had a higher alcohol content (13.97 +/- 0.03%) in each year of the study, which indicated that it ripened faster than other clones (13.06-13.08 %) and compared to the standard (13.04 +/- 0.07%). This finding suggested that the clone No. 010 could possibly have a significant economic impact and further increase popularity of Cabernet Franc in a cooler climate viticultural region. It was also found to have the highest contents of aldehydes (488 +/- 1.54 mg/L) and esters (322 +/- 0.71 mg/L) compared to aldehydes (452-467 mg/L) and esters (290-310 mg/L) measured in other wines. Finally, the highest amount of phenolic compounds (1220 +/- 40 mg/kg) and resveratrol (70 +/- 3.3 mg/kg) were found in the grapes of the clone No. 010. The present study revealed a strong correlation of total phenolic contents and anthocyanins with radical scavenging activities (0.936 and 0.929, P lt 0.001, respectively) indicating that this activity of wines was derived mainly from their phenolic compounds. Conclusion: The wine of the clone No. 010 contained the highest concentration of aldehydes, esters, anthocyanins, polyphenolics and resveratrol and consequently achieved the best tasting score. This clone may offer a new Cabernet Franc wine with geographical indication.

AB  - Aims: The selection of cv. Merlot clones performed in the Grocka winegrowing region, Republic of Serbia, and the study of agrobiological and technological traits of three selected clones and Merlot standard. Methods and results: The selection of clones was done using the method of individual clone selection in four phases over 15-20 years (Cindric, 2003). O.I.V. methods were used in determining the most important agrobiological and economic-technological traits of grapes. The results of studied traits of grape and wine suggest that the quality of the clones surpassed the quality of the standard. Although the highest values for most of the studied traits were obtained for clone 025, there was no statistically significant difference between the clones. Indeed, the significant distinction between the clones was obtained for total polyphenol content (TPC) and total anthocyanin content (TAC) in wines : the wine of clone 025 had the highest TPC and TAC values. According to the tasting scores, wines of the clones may be classified as quality wines with geographical indications. Conclusion: The selected clones were characterised by good quality grapes and wines. Improved viticultural parameters, versus the mother vine, indicate the need for further research work on the chemistry of both grapes and wines, aiming to better understand the characteristics of the selected clones and their market potential. Significance and impact of the study: The development of new clones (namely 022, 025 and 029) of better quality than the mother vine will, in the long term, lead to the introduction of the best clone(s) in viticultural practices and production. Until today, the clonal selection of Merlot has not been done in the Republic of Serbia and there are no recognised clones.
