PVY NTN -CP coat protein gene from a necrotic strain of potato virus Y (pvy ntn ) has been transferred into two potato Solanum tuberosum L. cultivars Mindenes and Somogyi kifli via Agrobacterium tumefaciens transformation. Expression of integrated PVY NTN -CP gene were confirmed for 33 (89 %) of 37 and 3 (75 %) of 4 kanamycin-resistant regenerants of potato cultivars Mindenes and Somogyi kifli respectively. The level of virus resistance against two virus strains (PVY°, PVY NTN ) of independent lines of transgenic potatoes varied between extreme resistance to susceptibility. The three independent lines of transgenic potatoes proved to be extreme resistant against both PVY strains.
