“…Conscious of the relevance of preserving these invaluable local genetic resources, and looking for the development of better adapted new grapevine cultivars and clones, the Arab Center for the Studies of Arid Zones and Dry lands (ACSAD) established in 1996 a Gene Bank collection in the Jillin Research Station after the prospection of locally-grown traditional varieties. Despite its wide interest, and in contrast to local genetic resources from nearby regions (Aroutiounian et al 2015;Basheer-Salimia et al 2014;Chalak et al 2016;Drori et al 2017;Ekhvaia et al 2014;Ergül et al 2002;Eyduran et al 2015;Fatahi et al 2003;Khadivi-Khub et al 2014;Lamine et al 2014), few local Syrian grapevine cultivars have been adequately described so far (Sawaf et al 1976).…”

Due to its unique historical and geographical emplacement, grapes have been cultivated in the Syrian Arab Republic for more than 5000 years, so the characterization of its local genetic resources is paramount for understanding grapevine natural diversity. In this work, different local Syrian table grape cultivars were characterized for 42 traits related to plant phenology, shoot, leaf, cluster, berry and juice composition. A series of multivariate analyses were sequentially performed, and five highly-discriminant traits were identified as the most discriminant ones (shoot internode length, berry weight, berry elongation, 100-seed weight and juice titratable acidity). The clustering of the cultivars according to these five traits revealed that some local Syrian cultivars share similitude with some worldwide grown cultivars, suggesting their potential as new genetic resources for the development of new high-quality table grape varieties, and indicating the needing of specific preservation programs aimed to avoid the loss of endangered genetic local resources. Besides, the statistical multivariate pipeline followed in this work is proposed as an efficient one for the selection of ampelographic traits for the discrimination of grapevine cultivars.

“…Together, the research conducted on wines and grapes grown and produced in Armenia and Georgia revealed apparent differences among the cultivated varieties and wild species with respect to their total phenolic content and antioxidant activity [37,38]. These differences imply that biological activity, and not simply taste, may represent an important "seal of quality" for these natural products and produce.…”

Cellular redox homeostasis is a state of balance between the formation of Usually Reactive Oxygen and / or Nitrogen Species (ROS/RNS), endogenous antioxidant defence systems, and exogenous dietary antioxidants. The disturbance of redox homeostasis, by the overproduction of endogenous ROS/RNS, may increase the risk of development of so-called civilisation diseases. The solution seems to be either the increased production of endogenous or consumption of exogenous antioxidants. Plant-borne antioxidants act via different chemical and molecular mechanisms, such as decreasing the level of oxidative damage in cells directly by reacting with ROS/ RNS or indirectlyby inhibition of the activity and expression of free radical generating enzymes or by enhancing the activity or expression of intracellular antioxidant defence enzymes. Despite the fact that the Caucasian flora is rich of health promoting edible/medicinal plants, recent studies concerning the biological activity of these plants are very scarce. This review is summarising the state-of-art on the health-promoting potential of plants representing the Caucasian flora, whose antioxidant capacity have been investigated in various in vitro models.

“…Having already been studied by the methods of ampelography, Armenian grapevine biodiversity still needs to be investigated on a molecular level in accordance with modern requirements. During the last few years, eighty Armenian cultivars have already been identified and characterized according to OIV phenotypic descriptors [7,8], but their genotypic characteristics are yet to be identified. The genetic analysis of Armenian grapevine cultivars is essential for the correct description of genetic resources and the ascertainment of genetic relationships between grapevine genotypes and their pedigrees.…”

Armenia is an important area of crop origins including grapes. The objectives of this study were the molecular characterization of 38 Armenian grape genotypes and the detection of the genetic relationships between the accessions. In total, 164 alleles were obtained at 18 SSRs loci. The number of alleles per locus ranged from 5 to 15 with a mean number of 9.17 alleles per locus. The expected heterozygosity ranged from 0.514 (VVIN73) to 0.90 (VVS2) and the observed heterozygosity from 0.417 (VVIV37) to 0.947 (VVMD7 and VMC1B11). In our research the highest values of polymorphic information content (PIC) were obtained using markers VVS2, VRZAG62 and VRZAG79, while the least informative ones were VVIN73 and VVIB01. A high level of gene diversity was observed between ancient and new bred cultivars. Higher values were recorded for the new grape varieties, (He = 0.792) and lower values for ancient cultivars (He = 0.739). The mean number of alleles (MNA) for all loci per population ranged from 7.39 in ancient to 8,00 in new crosses. A clear separation was observed for the groups of ancient aboriginal cultivars, Vitis vinifera L. xVitis vinifera L. and Vitis vinifera L. x Vitis amurensis Rupr .crosses, which were bred in Armenia and seedless cultivars. Very close relationships with high similarity were determined for 5 pairs of cultivars. Two cases of possible homonymy were also detected. Our results are the basis for future MAS selection and target breeding.
