Использование полиморфных микросателлитных локусов ДНК является одним из подходов к аутентификации виноматериалов и вин. При этом SSR-маркеры хлоропластной ДНК имеют большую копийность мишени на клетку и менее подвержены деградации из-за содержания в органеллах с двойной мембраной. Целью настоящей работы являлось моделирование технологии идентификации виноматериалов и вин ПЦР-анализом микросателлитных локусов хлоропластной ДНК винограда. Подобраны условия экстракции нуклеиновых кислот, постановки ПЦР с соответствующими наборами праймеров и электрофоретической детекции, направленные на практическое воспроизведение генетического тестирования пробоподготовленного биоматериала из осаждаемого винного дебриса. Представлены наглядные результаты выравнивания частичных нуклеотидных последовательностей аллелей микросателлитных локусов хлоропластной ДНК Vitis vinifera L. Проанализирована разделяющая способность метода горизонтального электрофореза в геле «Spreadex EL 300» in silico моделированием генерируемых аллельспецифичных фрагментов, позволяющая идентифицировать известные хлоротипы винограда даже при постановке ПЦР с ограниченными наборами праймеров, нацеленных на локусы cpSSR3, cpSSR5, cpSSR10, NTCP12 и ccSSR9. The use of polymorphic microsatellite DNA loci is one of the approaches to the authentication of wine materials and wines. At the same time, SSR markers of chloroplast DNA have a large target copy number per cell and are less susceptible to degradation due to their content in organelles with a double membrane. The aim of this work was to simulate the technology of identification of wine materials and wines by PCR analysis of microsatellite loci of grapevine chloroplast DNA. The conditions for the extraction of nucleic acids, PCR with the corresponding sets of primers and electrophoretic detection were selected, aimed at the practical reproduction of genetic testing of the sample prepared biomaterial from the precipitated wine debris. Illustrative results of the alignment of partial nucleotide sequences of alleles of microsatellite loci of Vitis vinifera L. chloroplast DNA are presented. The separating ability of the method of horizontal electrophoresis in «Spreadex EL 300» gel by in silico modeling the generated allele-specific fragments, which makes it possible to identify the known chlorotypes of grapevine with a limited set of primers targeting loci (cpSSR3, cpSSR5, cpSSR10, NTCP12 and ccSSR9) has been analyzed.

A prospecting work at the Axarquia region (Malaga, Spain) was carried out in order to identify local red grapevine cultivars preserved in ancient vineyards. A total of 11 accessions were collected in seven different plots from four municipalities and analyzed using 25 microsatellite loci for cultivar identification. The accessions analyzed were identified as eight different genotypes, seven of them corresponding to known cultivars as ‘Cabernet Sauvignon’, ‘Jaen Tinto’, ‘Molinera’, ‘Monastrell’, ‘Muscat of Alexandria’, ‘Parrel’, and ‘Romé’. In addition, one of them is referred to as the new genotype for ‘Cabriel’ cultivar. Additionally, an ampelographic characterization was carried out with 30 International Organisation of Vine and Wine (OIV) descriptors for two consecutive years for the eight accessions identified as local cultivars. This allowed the identification of a somatic variant of the ‘Muscat of Alexandria’ cultivar that affects the color of the berry and another of ‘Romé’ regarding bunch compactness.

Characterisations of thirty grapevine varieties (Vitis vinifera L.) from the experimental vineyard ‘Radmilovac’ were conducted using a large number of OIV descriptors and eight highly polymorphic microsatellite loci. The ampelographic description contained 45 features. Molecular characterisation of selected microsatellite loci was performed using capillary electrophoresis fragment analysis. Dendrograms based on ampelographic and genetic data resulted in three groups of varieties. Qualitative ampelographic characteristics tended to manifest significant differences. The most common deviation among varieties within the group was in the characteristic OIV 051 (colouration of the upper side of a young leaf). Genetic characterisation of SSR markers through analyses of a large number of varieties contributes to better organisation of grapevine collections and simpler identification of varieties, as well as data exchange. When identifying the varieties, the results of the DNA analysis should be combined with the ampelographic descriptors, in order to select grapevine varieties with desirable viticultural and oenological traits. Integration of the obtained genetic data with the ampelographic data is of utmost importance for accurate identification of the varieties and offers a significant means for the preservation and use of the varieties.

Thirty-one old Hungarian grapevine (Vitis vinifera L.) cultivars were investigated on 7 microsatellite loci to characterize them, to separate the cultivars from synonym names, and to confirm parent-offspring connections. Conculta (group of cultivars or bud sports) members, such as `Goher' and Tajor' representatives, were studied to find a suitable locus for the separation. Synonyms, conculta members, subcultivars and clones of Turmine, which was the most important cultivar of Tokaj, were also analyzed to separate the members of the different taxonomic levels. Pedigree of 'Kiralyleanyka' was examined to find the missing ancestor, because the parent-offspring connection between the natural hybrid and `Koverszolo' is questionable.
