Abstract


In 2000–2001 35 isolates of Potato virus Y (PVY) were characterized by serological and biological methods. These isolates represented 5 distinct strains: PVYC, PVYO, PVYN, PVYN W, PVYNTN. Among isolates belonging to PVYN W and PVYNTN isolates which are able to overcome the resistance in three tobacco cultivars (VAM, Wiślica, PBD6) were found. They were obtained from tobacco plants grown in Poland or Hungary. Isolates obtained from potato plants were able to cause only mild symptoms on cvs. Wiślica and PBD6.
