<p align="justify"><strong>Aims</strong>: 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.</p><p style="text-align: justify;"><strong>Methods and results</strong>: The selection of clones was done using the method of individual clone selection in four phases over 15-20 years (Cindrić, 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".</p><p style="text-align: justify;"><strong>Conclusion</strong>: 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.</p>

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.

Abstract. Growing interest in Serbia in adaptation of viticulture to climate change emerged from a recorded positive impact of summer increased draught on domestic wine quality. Another motivation is that viticulture has been recognized as one of the fastest developing agricultural sectors in Serbia and, to contain its growing potential, it is crucial to provide basis for its future sustainable development. Prioritization and implementation of adaptation measures in practice require reliable assessment of climate projections. For climate change impact assessment is used high resolution multi-model ensemble of nine regional climate models simulations, bias corrected, with two most probable future scenarios of GHG emissions RCP4.5 and RCP8.5, for the period 2016-2100. Analysis has been done for the near future, mid-century and end of the century periods. The periods are defined according to the IPCC 5 th Assessment Report, which enables comparison of climate change impacts with a wider region, and preferably motivate future international collaboration and knowledge exchange.
