“…Similarly, previous studies have reported that VVS2 (Fatahi et al 2003, Núñez et al 2004, Şelli et al 2007) and VVMD28 generate the highest number of alleles (Vouillamoz et al 2006(Vouillamoz et al , Şelli et al 2007). Other studies, including ours, have also reported that VrZAG83 generates the lowest number of alleles (Sefc et al 2000, Snoussi et al 2004 (Table 2). …”

: Turkey is one of the centres for grapevine diversity with many local grapevine cultivars with potentially desirable characteristics are still widely cultivated throughout several regions in the country. One of such regions is the Eastern Mediterranean region of the country. To characterize the grapevine germplasm of this region, we performed a genetic analysis of 59 grapevine cultivars using 14 simple sequence repeat (SSR) loci. The genetic relationships of the cultivars which did not appear to be linked to their ecogeographical distributions within the region were determined. Among the cultivars analyzed in this study, several synonymous and homonymous cultivars were identified, suggesting that some of the grapevine cultivars with different names might be genetically identical while some cultivars with the same names might be genetically different. This study represents a first step toward the genetic characterization of the grapevine genotypes of this region and will help promote more effective germplasm management and breeding programs.

“…However, the allele richness detected in the nuclear SSR loci and the high heterozygosis of grapevine clones render this analyses less efficient when the aim is the definition of genetic relatedness among large groups of cultivars Imazio et al 2006). Cp-SSR markers, on the contrary, proved to be particularly useful in the study of cultivar origin (Arroyo et al 2002; Palmé and Vendramin 2002;Snoussi et al 2004). A general conclusion was that the use of Cp-SSRs in the study of domesticated grapevine revealed an increase in haplotype number from East to West, suggesting that grapevine diversity is higher in the Mediterranean basin.…”

Archaeobotanical-archaeological, cultural and historical data indicate that grapevine domestication can be dated back from 6000 to 7000 years ago and that it took place in the Caucasian and Middle East Regions. However, events leading to the domestication of this crop species are still an open issue. In this paper, 6 chloroplast microsatellites have been used to assess genetic similarities among, and within, domesticated and wild grapevine ac-cessions representative of 7 distinct geographical regions from the Middle-East to Western Europe. Results show that 2 out of the 6 analyzed chloroplast loci are polymorphic within the 193 domesticated individuals and the 387 samples of 69 wild populations. Allele variants of the Cp-SSR loci combine in a total of 6 different haplotypes. The data show that the haplotype distribution is not homogeneous: the 6 haplotypes are present in the domesticated varieties, but only 5 (haplotype VI is absent) are observed in wild populations. The analysis of haplotype distribution allows discussion of the relationships between the two grape subspecies. The contribution of the wild grape germplasm to the domesticated gene pool still growing in different geographical regions can be, in cases, made evident, suggesting that beside domestication, gene introgression has also played a role in shaping the current varietal landscape of the European viticulture.

Equipe DAVEM = Diversité et Adaptation de la Vigne et des Espèces Méditerranéennes Contact : ai.oualkadi@gmail.comGrape diversity present in Morocco and the part of this diversity used nowadays are poorly documented. In order to choose diversified genotypes, to select them so that their agronomic interest will be tested, a group of 21 autochthonous cultivars preserved in the germplasm collections of SODEA and 18 Moroccan cultivars from "Domaine de Vassal" INRA grape collection was compared to a group of cultivars from neighbouring countries (Algeria and Tunisia), and from a core collection optimizing simple sequence repeat (SSR) allelic diversity of grape. Data from 20 nuclear and 3 chloroplastic SSR markers were obtained for this set of 211 cultivars. A total of 156 alleles (mean of 7.8 alleles per locus) were detected for the nSSRs and 7 alleles for the cpSSR in the Moroccan group. Chlorotype diversity in Moroccan and Algerian group were similar, but slightly lower than in the Tunisian group and the core collection. Similarly, the nSSR diversity was high in the core collection and low in the Moroccan and the Algerian groups compared to the two other groups. Clustering of cultivars based on nSSR data reflected their geographical origin and, to a certain extent, the use of the cultivars. The specificity of the Moroccan plant material was attested by the Bayesian analysis using Structure, while differences of the core collection were clearly revealed both by the Bayesian and a multivariate analysis. These results confirm the differentiation of the material from Maghreb and more specifically of Moroccan material, having evolved independently from Europe
