Turkey, one of the few important countries in the world concerning the total area of the vineyards and grape production is not in a desired level considering the amount of grape yield per unit area. The use of materials of unknown quality and whose disease and pest related conditions are not taken into account in sapling production, which is the basic material of grape production, is the main cause of this fact. Plant pathogen viruses, for which no cultural or chemical fight against are unknown, are more important than other disease and pest organisms during sapling production processes. Elimination of the viruses from the base materials used in sapling production in viticulture is only possible with thermotherapy and meristem culture. In this study, the clones of fourteen grape varieties (Vitis vinifera L.) and six rootstocks that have economic importance for our country were used to purify from Agrobacterium vitis and viruses specified in the certification system of our country and European Union countries using thermotherapy and meristem culture methods. 93 plants were obtained at the end of purification processes of the studied clones grape cultivars and rootstocks.
