Résumé
Georgian grapevine germplasm (V. vinifera L.) originated in diverse regions of the country over a long historical period. During the XX century bred varieties enriched it. Georgia is also a place where V. vinifera sylvestris spread in large numbers, provided an important initial impulse to the domestication of grapevine. The main cultivated varieties in Georgia are autochthonous varieties, having high-market value – best of those are also cultivated in East Europe and Middle Asia. Conservation initiatives for Georgian Vitis germplasm started since XIX century and entered into XXI century with some difficulties. However, Georgia was able to establish new field collections and collaborative works, in the framework of international projects and local initiatives. This germplasm is the object of intensive investigations; it attracts international collaborations because of its genetic diversity. Investigations based on SSR fingerprinting and ampelographic methods are used for classification of varieties and understanding their phylogenic relationships.
