Abstract
The autochthonous grape cultivar assortment in Serbia has been reduced to a few cultivars.
This paper presents results of varietal selection of autochthonous cultivars ‘Smederevka’ and Prokupac, which was conducted first time in Serbia. ‘Smederevka’ is a cultivar with two main uses of combined use (table and wine grape production). ‘Prokupac’ is an old autochthonous cultivar that, in addition to wine production, has been used in breeding programs to create new cultivars.
So far, 4 clones of ‘Smederevka’ and 12 clones of ‘Prokupac’ cultivar have selected.
The results of the study refer to mechanical composition of grapes and berries, as well as to qualitative parameters of grape juice (sugar content, total acidity and pH). For the ‘Smederevka’ cultivar, clone ‘Zoran’ (385.6 g) had the highest cluster weight determined, while ‘Nebojša’ (207.75 g) had the lowest.
Clone ‘Zoran’ (18.2%) had the highest sugar content, followed by clones ‘Slavica’ (17.6%), ‘Nebojša’ (17.4%) and ‘Ljubica’ (16.6%). The highest content of total acids was determined in the grape juice of the clones ‘Nebojša’ (6.02 g L-1) and ‘Slavica’ (5.95 g L-1). Among the ‘Prokupac’ clones, clone PR 13 had the largest cluster length, while the widest cluster was recorded for clone PR 19 (10.24 cm). Clone PR 9 had the highest percentage of cluster stem (5.3%), but the lowest percentage of berries in the cluster (94.7%). Clone PR 6 was characterized by the highest accumulated sugar (22.05%), while the highest total acid content was found in clone PR 2 (8.53 g L-1). Clones classification or identification can helps to increase the gene pool and the intra-varietal diversity.
They have improved technological characteristics and oenological potential.
Their expansion are suitable basis for production of wines with protected geographical origin from autochthonous cultivars, which can be included in the list of new brands on the wine list of Serbia.
