1. Importance of the Viticulture in the country According to the last national Agro Census (2004) there were 37419 ha of in Georgia in 2004.

3. Status of characterization of the collections  For most of collections the FAO-Bioversity Multicrop Passport Descriptors are completed. For ‘Shumi’, ‘Jighaura’ and ‘Kindzmarauli’ collections their preparation is in progress.  In the ‘Skra 1’ collection all Georgian native varieties and 19 local breeding new varieties and forms have been characterised by OIV descriptors (48 descriptors suggested in COST project) in previous and recent year. Phenological observation is also organised in this year for most varieties in the collection. The photos of grape organs have been takes.  310 varieties from ‘Kindzmarauli’, ‘Jighaura’, ‘Telavi 1’ and ‘Shumi’ collection have been characterised by IPGRI (1997) descriptors in 2010.  150 Georgian varieties from Gorizia collection (Italy) were characterised by 59 ampelographic and 84 ampelometric descriptors; Phenological records for 5 years were collected; Antocianin profiles for 84 coloured varieties were evaluated.

6. Table grapes In spite of consumption some amount of table grape in Georgia commercial plantation of table grapes is imitated in the country. The most plantations are available in backyards and grapes are used mostly for domestic consumption. Recently some companies like “Khareba” or “AGRO” Centre made plantation of Table grape.

Table grape varieties, recommended for cultivation in Georgia (The law of Georgia “About Vine and Wine”, 1998) Berry colour Recommended Varieties White Gorula Kartuli Saadreo, Kolkhuri, Muskaturi Rkatsiteli, Sakhalkho Tetri, Tbilisuri Karabournu, Khalili, Chasselas blanc, Tabrizi (sin. Ganjuri in Georgia) Coloured Budeshuri Tsiteli, Tskhenis Dzudzu, Tskhenis Dzudzu from Abkhazia  Except recommended varieties private persons have other varieties too.

7. Selection or breeding programmes in course The recently funded programme not available. Our department is keeping in collections several breeding forms from previous programs, worked in Georgia in XX century. Twelve table grape forms among those can be recognised as candidates for registration of new varieties.

8. Clonal selection status Recently no one clonal selection program works in the country in spite of tradition of XX century.

9. Catalogue or reliable publication with a list of the confirmed synonymies The list of Georgian cultivars and rootstocks, recommended for cultivation, has been prepared in the framework of GrapeGen06 project, was published in the journal “Vitis” (Lacomber et al. 2011) and at the European Vitis Database. An official catalogue or reliable publication for all grape genetic resources of Georgia not available in the country. This information, but fragmentised, is available in scientific literature published in various period. 4

10. Number of endangered cultivars Exact number and precise list not known for this moment, while preparation of the list of new ‘Jighaura’, ‘Kindzmarauli’ and ‘Shumi’ collections is under progress. We just can do approximately calculation based on previous (year 2004) inventory of collections made in the framework of Bioversity International project: i) number of unique names of autochthonous varieties, protected in our collections (‘Dighomi’, ‘Vashlijvari’, ‘Mukhrani’, ‘Telavi 1’, ‘Skra 1’) was 300. ii) According to Ketskhoveli et al. (1960) total number of Georgian autochthonous varieties is 525. iii) So maximum 225 varieties can be recognised as endangered varieties. In reality this number is less for today due to large number of varieties protected in three new collections mentioned above.

13. Use of microsatellites in characterization Microsatelites are used for characterisation of Georgian grape germplasm since 2006 (Maghradze et al. 2009) with collaboration University of Milan and INRA-Montpellier. At the beginning 147 accessions was characterized by 6 basic SSR markers. After of this 135 accessions - including 22 wild grapes from Georgia - were characterised by 20 SSR markers (Imazio et al. 2010). In this year 11 SSR markers were used for characterisation of 46 Georgian native varieties (Maghradze et. al. 2012) in the framework of COST project.

14. Sanitary status of the propagated material There is not any law or centralised regulation requesting obligatory checking for sanitary status of planting materials. But nurseries tried to keep materials free of virus as they can do by their self. For example like “ARGO” established virus testing laboratory; another nurseries have planted virus free mother materials for propagation.

16. Occurrence of Vitis sylvestris in wild habitats Old autochthonous cultivars exist, but figures are not available. Not clonally selected material exists, while clonally selected materials are very few for Georgian autochthonous varieties, but figures not available.

18. Neglected cultivars In the materials of last National Agro Census (2004) are listed 42 cultivars, among which 32 are Georgian cultivars. If we shell take in consideration, that total number of old Georgian native varieties is 525 (Ketskhoveli et al. 1960), number of neglected cultivars, presented in repositories only or disappeared will be 493: this correspondents to 93,9% of the total germplasm.

19. Occurrence of Vitis sylvestris in wild habitats Vitis sylvestris still occurs in the wild habitats of Georgia, which was demonstrated by investigation of last years (Maghradze et al. 2006; 2010, Sharikadze et al. 2010, Ocete et al. 2012).

20. On farm evaluation and maintenance There are very few examples for on farm maintenance like Kakhuri Mtsvivani by winery “Kindzmarauli Corporation” in district; Kisi by winery “Khareba”; several local varieties by farmers of “Elkana” Association. This method of preservation need to be father improved in Georgia.

18. Realization of prospections There are not any specific projects for realization of these prospections recently.

19. Preservation of clones No particular attention paid to preservation of clones

20. Organizations responsible for grape germplasm There is not any specific organization responsible for grape germplasm like gene banks or coordinating activities in Georgia. Just Vice-President of Georgian Agricultural Academy G. Alexidze is the Coordinator of the genetic resources of Georgia.

21. National or regional programs or projects Recently is not any regional programs / projects in the country.
