Abstract

In order to increase the number of grape genotypes adapted to in vitro manipulation studies, an investigation on the regenerative potentiality in the Vitis genus was conducted on cultivars of Vitis vinifera L., (Barbera, Cabernet franc, Cabernet Sauvignon, Canner Seedless bianco, Chardonnay, Enantio, Moscato bianco, Riesling, Sultana moscato bianco and Sultanina rouge), V. vinifera silvestris G., V. amurensis R., V. armata D. and G., V. riparia M., V. simpsonii M., as well as the rootstocks 110 Richter and Schwarzmann, and the interspecific variety Staufer. Regeneration was induced via direct organogenesis from young leaves, and a relevant genotypic influence on the morphogenic potentiality was observed. Among the 18 different genotypes tested, regeneration occurred with different efficiencies and precocity. Agreeable efficiencies were obtained for Sultana moscato, Riesling, Chardonnay and Cabernet franc, while Enantio and Cabernet Sauvignon were recalcitrant to shoot regeneration. V. armata was the most favourable to this regeneration system.
