<p>This study presents the results regarding the identification and discrimination of twenty seven possible clones of grapevine cultivar Korinthiaki staphis (<em>Vitis vinifera</em> L.), three biotypes of Korinthiaki lefki and the related cultivar Staphidampelo using the ampelographic description and the molecular method AFLP. The results from the statistical analysis showed that all the biotypes of cultivar Korinthiaki staphis show small distance and are grouped in the same cluster, depending on their origin, while Staphidampelo and Korinthiaki lefki are neither variants nor biotypes of the cultivar Korinthiaki staphis but different cultivars since they are very distant compared to the other biotypes and moreover, Korinthiaki lefki is in a separate cluster of the dendrogram. The ampelographic description in combination with the molecular method AFLP are effective for the study of the between and within genetic diversity of grapevine cultivars as well as for their identification and discrimination. The results of this study can constitute the base for the implementation of the clonal selection for grapevine cultivar Korinthiaki staphis and the seclusion of the desired clones.</p>

The grapevine cultivar Albariño (Vitis vinifera L.) is one of the most economically important of northwestern Spain. It is also grown in northern Portugal. The present work examines the results obtained by two clonal selection processes involving this cultivar. The first of these was begun in 1987 by the Viticulture Research Group of the Spanish Research Council (CSIC). This involved centuries-old mother plants showing small ampelographic or agronomic differences. The second process was begun in 1989 by the wine-making company Bodegas Terras Gauda S.A. This involved the use of centuries-old ‘Albariño’ plants too, but also of other plants no older than 20 years of age. The number of mother plants originally examined in the CISC procedure was 40, but only eight were finally selected and planted (at the Misión Biológica de Galicia Research Station). In the procedure followed by Bodegas Terras Gauda S.A., 115 mother plants were originally planted. The characteristics of the eight CSIC clones and the 22 surviving Bodegas Terras Gauda S.A. clones were determined. The variability of the eight CSIC clones was found to be greater. It is recommended that candidate materials for use in clonal selection programs be examined for differences in situ before being admitted to collections.

История виноградарства на Дону насчитывает несколько веков, местные сорта винограда многообразны и специфичны. Микросателлитные маркеры широко используются для генотипирования сортов и подвоев винограда, при изучении происхождения сортов и анализе их родословной. Целью исследования было изучение выборки редких и малораспространенных автохтонных донских сортов и сравнение их с другими аборигенными донскими генотипами на основе данных ДНК-анализа. В исследования включены 23 стародавних донских сорта. Генотипирование проводили методом микросателлитного профилирования. В исследовании использовали микросателлитные маркеры (SSR), рекомендованные в качестве основного минимального набора для ДНК-паспортизации сортов вида Vitis vinifera L.: VVMD5, VVMD7, VVMD27, VVS2, VrZAG62 и VrZAG79. По результатам проведенного анализа все изученные образцы показали сорт-специфическую комбинацию аллелей в идентифицированных ДНК-профилях. Количество выявленных аллелей составило в среднем 8 аллелей/локус. Наибольший полиморфизм в исследовании этой группы донских сортов был обнаружен в локусе VVMD5: идентифицировано 10 аллелей на локус, наименьшее - в локусе VrZAG62: 6 аллелей/локус. Основываясь на данных SSR-анализа, степень генетического сходства сортов оценивали с использованием метода UPGMA. Кластерный анализ матрицы генетических дистанций, созданный на основе выявленных значений аллелей в шести микросателлитных локусах исследуемых сортов, определил несколько групп генотипов. Сорт Красностоп золотовский выделился в отдельную ветвь, что указывает на различия между этим генотипом и другими сортами исследуемой выборки. Наивысший уровень генетического сходства наблюдался между следующими парами сортов: Крестовский и Бургундский, Шилохвостый и Мушкетный, Кумшацкий черный и Ефремовский.The history of viticulture on the Don goes back several centuries. Local grapevine varieties are diverse and peculiar. Microsatellite markers are widely used in genotyping grapevine cultivars and rootstocks, in grapevine origin and breeding background analysis. Our study aimed to examine samples of rare and less common autochthonous Don varieties, and compare them with the other aboriginal Don genotypes using DNA data. The study involved 23 traditional Don varieties. The genotyping was done by microsatellite profiling. The study used microsatellite (SSR) markers recommended as the basic minimum set for DNA-certification of the genotypes of Vitis vinifera L.: VVMD5, VVMD7, VVMD27, VVS2, VrZAG62 and VrZAG79. Based on the findings, all the studied samples demonstrated variety-specific combination of alleles in the identified DNA profiles. The number of detected alleles on average was 8 alleles/locus. The greatest polymorphism in the studied group of Don varieties was detected in VVMD5 locus: 10 alleles per locus were identified, the smallest in VrZAG62 locus: 6 alleles/locus. UPGMA method was used to assess the extent of genetic similarity of the varieties based on SSR-genotyping data. Based on determined allele values of the studied varieties, cluster analysis of the genetic distances matrix determined several groups of genotypes. ‘Krasnostop zolotovskiy’ variety stood out as a separate branch, which indicates the difference between this genotype and the other varieties of the studied sampling. The highest level of genetic similarity was observed between the following pairs of varieties: ‘Krestovskiy’ and ‘Burgundskiy’, ‘Shilohvostyi’ and ‘Mushketnyi’, ‘Kumshatskiy chornyi’ and ‘Efremovskiy’.

222 cultivated (Vitis vinifera) and 22 wild (V. vinifera ssp. sylvestris) grape accessions were analysed for genetic diversity and differentiation at eight microsatellite loci. A total of 94 alleles were detected, with extensive polymorphism among the accessions. Multivariate relationships among accessions revealed 16 genetic groups structured into three clusters, supporting the classical eco-geographic grouping of grape cultivars: occidentalis, pontica and orientalis. French cultivars appeared to be distinct and showed close affinity to the wild progenitor, ssp. sylvestris from south-western France (Pyrenees) and Tunisia, probably reflecting the origin and domestication history of many of the old wine cultivars from France. There was appreciable level of differentiation between table and wine grape cultivars, and the Muscat types were somewhat distinct within the wine grapes. Contingency χ2 analysis indicated significant heterogeneity in allele frequencies among groups at all loci. The observed heterozygosities for different groups ranged from 0·625 to 0·9 with an overall average of 0·771. Genetic relationships among groups suggested hierarchical differentiation within cultivated grape. The gene diversity analysis indicated narrow divergence among groups and that most variation was found within groups (∼85%). Partitioning of diversity suggested that the remaining variation is somewhat structured hierarchically at different levels of differentiation. The overall organization of genetic diversity suggests that the germplasm of cultivated grape represents a single complex gene pool and that its structure is determined by strong artificial selection and a vegetative mode of reproduction.

The quality of grapes is determined above all by the contents of the primary and secondary metabolites. The primary metabolites involve sugars and organic acids, and just these compounds are dealt with in this study. Its objective was to analyse and critically evaluate the primary metabolites in new interspecific varieties and, based on a comparison with European varieties of grapevine (Vitis vinifera L.), to find out the similarities and also possible differences between them. The study evaluates and compares 4 conventional varieties of Vitis vinifera with 11 new interspecific cultivars. The contents and compositions of the individual sugars and acids were estimated by means of the HPLC method. Most of these varieties belong to the group with either medium or low content of malic acid, i.e. with a medium to high &beta; ratio. This corroborates the similarity of interspecific varieties to those of V. vinifera. The cluster analysis identified the existence of two interesting groups of varieties: the first one involved the varieties Riesling, Nativa, Marlen, and Kofranka while the other group consisted of varieties Blaufr&auml;nkisch, Blauer Portugieser, and Laurot. This observation also indicates similarity between Vitis vinifera L. varieties and interspecific cultivars and demonstrates that the contents of the primary metabolites (i.e. sugars and organic acids) are also comparable.

Although compost and biochar received high attention as growing media, little information is available on the potential of vineyard by-products for the production and use of composted solid digestate (CSD) and biochar (BC). In the present study, two experiments are reported on CSD and BC mixed with commercial peat (CP) for grapevine planting material production. Four doses (0, 10%, 20%, 40% vol.) of CSD and BC were assessed in the first and second experiment, respectively. CSD mixed at a dose of 10% recorded the highest values of shoot dry weight (SDW) and a fraction of total dry biomass allocated to shoot (FTS), both cropping bench-graft and bare-rooted vine. On the other hand, CSD mixed at a dose of 40% displayed the highest values of SDW and FTS, cropping two-year-old vine. BC used at a dose of 10% improved SDW, root dry weight, total dry weight, FTS, shoot diameter, and height on bare-rooted vine. The present study shows that CSD and BC, coming from the valorization of vineyard by-products, can be used in the production of innovative growing media suitable for nursery grapevine production. Further studies are needed to assess the combined applications of CSD and BC in the same growing media.

AbstractMicrosatellites were used as a very effective tool for genetic diversity analysis and characterization of 51 grapevine (Vitis vinifera L.) accessions from the national collection of genetic resources. Genetic diversity was relatively high, 8.91 alleles were detected per analysed microsatellite locus in average, and fifty-one accessions were distinguished into 45 groups. Distribution of recent Slovak cultivars across the dendrogram accented both their genetic diversity and the effectiveness of the national breeding program in maintaining genetic diversity and generating new genetic variants. Each cultivar was different from the others and twelve of them contained 77.6% of the total genetic diversity of the whole analysed set. Microsatellite patterns were also able to confirm parentage in selected Slovak cultivars. An unusual phenomenon of triallelism was also detected in one of the analysed accessions. The present study has initiated molecular characterization within the national grapevine genetic resource collection and their comparison with well-established international cultivars.
