In vitro propagation is a commercial technique that is used for different plants propagation around the world. Therefore, the development of in vitro techniques is a sure way for rapid propagation of many plant species. In this study, effect of Woody Plant Medium (WPM) and Murashighe and Skoog (MS) media supplemented with 0.0, 2.2, 4.4, 6.6 and 8.8 µM Benzyladenine (BA) on regeneration of three grape cultivars (Bidaneh Sefid, Farkhi and and Khoshnav) were investigated. In proliferation stage, length of shoots, number of shoots, number of leaves and the final status of explants were evaluated. In rooting stage, effect of indole-3-butyric acid (IBA) in three concentrations (0.0, 0.5 and 1.0 µM) on root initiation, number of rooted explants, root length and number of roots were evaluated. The results showed that longest shoots were obtained in MS medium supplemented with 2.2 µM BA in the three cultivars, while most appropriate shoots were observed in MS medium containing 4.4 µM BA in three cultivars. In rooting stage, the best results was obtained by 0.5 µM IBA. The results of this study showed that grape regeneration potential in vitro conditions depend to cultivar, culture medium and different concentrations of growth regulators.
