We elucidate grapevine evolution and domestication histories with 3525 cultivated wild accessions worldwide. In the Pleistocene, harsh climate drove separation of grape ecotypes caused by continuous habitat fragmentation. Then, occurred concurrently about 11,000 years ago in Western Asia Caucasus to yield table wine grapevines. The domesticates dispersed into Europe early farmers, introgressed ancient western ecotypes, subsequently diversified along human migration trails muscat unique...
The genetic diversity and relationship between wild (Vitis vinifera L. subsp. sylvestris (Gmel.) Hegi cultivated (V. vinifera) grapevine in the western Balkan region Central Europe have not been studied together previously, although this area has a rich viticultural past. Here, we populations sampled from their natural habitats several countries of Europe. Their structure were compared to cultivars that are traditionally use region. A sample set 243 accessions was genotyped at 20 nuclear...
Molecular markers and mapping are used to analyze an organism’s genes. They allow the selection of target genetic areas based on marker genotype (and not trait phenotype), facilitate study variability diversity, create linkage maps, follow individuals or lines carrying certain may be select parental genotypes, remove drag in back-crossing, choose difficult-to-measure characteristics. Due a lack variety crops, gene pools wild crop relatives for future agricultural production have been...

Somatic embryogenesis (SE) is a widely used technique in plant biotechnology, and it can be possible tool for virus viroid elimination. This review highlights the advantages limitations of production pathogen-free plants using somatic embryogenesis. Beside well-known meristem cultures, chemotherapy, thermotherapy cryotherapy, SE very effective elimination method. Production virus- viroid-free categorized based on latest taxonomy. The available information spread calli effect morphological...
Null alleles are that recessive to codominant markers without any effect on the phenotype. In SSR assays, there several reasons for lack of amplification at a locus: primer does not bind well, longer fragments do amplify due imperfections in PCR reaction, or amount DNA sample is insufficient. microsatellite studies, null mostly used pedigree analysis and population genetics calculations such as diversity estimation. can cause rejection true parent; if recognized while they distort results...
Somló-hill is Hungary's smallest wine district; however, it produces some of the best white wines. Viticulture dates back about 2000 years in district, and climate balanced. Former volcanic activity was an important factor development brown forest soils (Cambisols). Experiments were conducted 2006–2008 vineyards located upper zone (above 200 m sea level) for studying most adaptive environmentally friendly soil cultivation nutrient-supply methods. The following treatments applied four...
Conservation of grapevine genetic resources is an important and long lasting task. Here, partners the InWiGrape Activity European Cooperative Programme for Plant Genetic Resources have proposed a set descriptors that will assist in identification, conservation study Vitis vinifera L. subsp. sylvestris. A distribution map sylvestris populations Europe was produced, with on-line access through Database. The several different aspects including bibliographical references, identification wild,...
The frost hardiness of 102 traditional and newly bred Hungarian Vitis vinifera interspecific cultivars were tested using artificial treatments in climatic chambers. sugar content treated buds was analysed for sucrose, glucose, fructose raffinose by over pressure layer chromatography. belonging to convar. Pontica, are regarded as tender cultivars, but some these varieties which can only be found gene banks showed fairly good tolerance. In the new V. varieties, ‘Cserszegi fűszeres’ ‘Generosa’...
Due to climate change, the sugar content of grapes in Hungary has increased so high alcohol alone can make wines disharmonious. In most vintages, this phenomenon is only a problem for early-ripening varieties. order prevent and treat difficulty, we have been carrying out experiments grape canopy management four years with aim delaying ripening thus reducing grapes. The were set up on an early (Pinot noir) late (Welshriesling) variety; two treatments (leaf re-moval - LR short topping ST)...
In the case of indigenous grapevine varieties, aim clonal selection is twofold: to improve their technological cultivation problem while preserving varietal character. As sensitivity perennial crops climate change becomes more pronounced, selection, which already very time-consuming for woody crops, may take even longer. Badacsony, breeding ‘Kéknyelű’ and ‘Juhfark’ varieties was started in early 2000s. The mentioned above technology poor fertility (functionally female-flowered variety), high...
As the sensitivity of perennial crops to climate change becomes more pronounced, clonal selection, which is already very time-consuming for grapevine, may take even longer, while its importance increasing. In case indigenous grapevine varieties, purpose selection twofold: mitigate problems cultivation and at same time, preserve varietal character. The technique issue ‘Kéknyelű’ low fertility (functionally female-flowered variety), as ‘Juhfark’ it significant susceptibility grey rot. Based on...
The aim of this work was to determine the SSR profiles 96 Vitis accessions (mainly rootstocks) for 19 loci, and find genetic relatedness among them. Most molecular markers used in last 30 years are not affected by environment, giving a good tool determination distances. Based on our earlier experience, analysis carried out grape accessions, mainly rootstocks. Analyses were with microsatellite loci. loci selected cover all linkage groups get more precise impression genome Results analyses...
The real origin (crossing partners) of rootstocks and their clones derived from Teleki’s seedlings are still unknown. Therefore, as a first step, we aimed at determining the genetic similarities or differences among these by molecular tools. We have analysed 38 different seven microsatellite loci (VVMD5, VVMD6, VVMD7, VVMD28, VVMD31, VVS2, VVS29). relatedness can be inferred results presented in this paper.

The proof true-to-typeness is highly important ex-situ conservation, because contamination risk very high. Some characteristic...
New grape growing technologies are needed to face the global warming and climate change, especially for production of high-quality wines from late harvested grapes, which in standalone involved a high risk.
