AB  - This study examined influence of two different vineyard management practices – biodynamic (BIO) and conventional (CON), applied in a vineyard of a red wine variety Prokupac, (Serbia, 43°18’ 29” N 21°23’15”E), on grape berry quality parameters: soluble solids (SS), pH, total acidity (TA), total phenolic content (TPC), radical-scavenging activity (RSA), and total anthocyanin content (TAC). Both investigated vineyard management approaches were combined with two different winter pruning levels (the bud number per vine was 10 and 20, respectively). Soluble solids content was not influenced by different managements, but very significant differences were found in different bud loads treatments. SS showed significantly higher accumulation in berry in lower bud load treatment, 10 buds (23.8 0 Brix) compared to the 20 bud load (21.7 0 Brix). On contrary, TA showed significant differences between managements, BIO (6.65g L-1) and CON (6.44g L-1). There were differences in TPC between BIO and CON treatments (4.86 and 4.16 mg GAE g-1 respectively). While TPC was significantly higher in the BIO management treatment, bud load treatments were not affected this characteristic. Total anthocyanin content (TAC) was affected only by the management practices and was significantly higher in CON management treatment. Mean value for TAC were 0.10 mg mal-3-glu g-1 (BIO), 0.19 mg mal-3-glu g-1 (CON). TPC, RSA and TA were significantly higher in the biodynamic management treatment compared to the conventional, whereas the pruning level did not affect these attributes. SS content was not influenced by different managements, but different bud load has had. There were not significant differences in pH between applied treatments. These results indicate that the Prokupac has achieved favorable results under the biodynamic management, in terms of quality of wine grapes. In both trailed pruning level treatments, the lower bud number per vine (10 buds) was more favorable. These results clearly justify further research of this topic, with the overall aim to get a full picture of the effect of biodynamic vineyard long management practice on grape quality in Prokupac variety.

AB  - Qualitative and quantitative content of phenolic compounds in monovarietal wines of seven Serbian and two international varieties was determined and compared. The results showed that the variety influences the composition and content for most phenolic components determined in wines. The largest number of phenolic compounds (15) was detected in ‘Prokupac’ wine, while the smallest number (10) was found in ‘Smederevka’ wine. Hidroxybenzoic and hidroxycinnamic acids had the strongest discriminating effect. PCA indicated that phenolic composition depends on both the variety and the vintage, while in some cases their interaction was also manifested. From Serbian variety ‘Prokupac’ wine had the most specific phenolic profile.

AB  - The first reported occurrence of Vitis vinifera in Balkan dates in the Neolithic period in the form of wild grape. Early traces of viticulture and winemaking in the territory of Serbia are vessels from the Iron Age (~ 400 BC) and the Bronze Age (~ 200 BC). Over the last few decades, interest in autochthonous varieties in Serbia is constantly increasing, especially for growing native varieties, such as Prokupac, Smederevka, Tamjanika and Bagrina. Prokupac is the most important Serbian autochthonous red wine variety (the first written records about growing Prokupac in Serbia date from 12th century), well adapted to the ecological conditions of its birthplace with corresponding phonological features. When compared with germplasm representing the classical ecogeographic grouping of grapevine cultivars, Prokupac is clustered within the Convar pontica subconvar balcanica taxon, supporting his indigenous origin. The main objective of this work is to present characterization of the Prokupac variety by means of ampelographic and molecular analysis, as well as grape and wine chemical characteristics. Long-term cultivation in diverse ecological conditions has caused the Prokupac to become a mixture of clones (genotypes). Therefore in order to preserve and improve autochthonous grapevine varieties in Serbia, work on variety clonal selection was initiated and till now, 12 clones of Prokupac were already identified and recognized. The most important features of these clones will be also presented.

AB  - Central Balkan region is at the crossroads between Asia and Europe, on the line dividing various nations and civilizations of the East and the West. Due to its favorable climate and geological characteristics, it is an ancient wine growing region hosting a wide range of indigenous grapevine varieties, most of which are not internationally recognized.Also, numerous traditional local varieties, present in this area for centuries, are out of cultivation. Therefore, preservation and characterization of grapevine germplasm is important not only for the breeding process, but also for the improvement of modern varieties and their preservation for the future generations. Also, indigenous varieties as valuable resource of gen donors could be helpful when facing the challenges of climate changes. Unfortunately, during the last decade grapevine germplasm is undergoing a process of rapid genetic erosion, and as a consequence we are facing with the loss of varieties which are traditionally related to different winegrowing regions. The only way to prevent the loss of this heritage is to locate them, evaluate, preserve and precisely characterize them. In this Chapter the results of morphological and genetic characterization, as well as chemical characterization of some of the most important indigenous grapevine varieties in the central Balkan, such as Vranac, Krstač, Smederevka, Prokupac, Žilavka, Plavac Mali, and Istrian Malvasia will be summarized. These old varieties have passed through the process of natural selection and adapted to particular environmental conditions. As such, they represent irreplaceable genetic value for each country, and for the entire region.
