The work of recovering and preserving biotypes and varieties is very important in order to develop and strengthen the viticulture and viniculture traditions in some vine-growing areas. During the last ten years several different biotypes have been collected in the hills and along the Tyrrhenian coast, in the Latium and Tuscany regions. Most of them were autochthonous varieties; some biotypes still need to be correctly identified and described. The ELISA test was carried out on all the materials collected, in order to detect the most important viruses (GFLV, ArMV, GLRaV-1-2-3, GVA and GFkV). Some samples were further analysed in order to detect other viruses (GLRaV-6, -7, GVB, RSPaV). The paper showed the high occurrence of viruses, which were present especially in mixed infection form. Some biotypes showed a good sanitary level with regard to the most damaging virosis. Furthermore, virus occurrence varied according to the recovery areas as a result of field propagation.
