Cultivated Potatoes

Potato (Solanum tuberosum L.) is the fourth most important food crop in the world. It is the most economically valuable and well-known member of the plant family Solanaceae. Potato is the host of many pathogens, including fungi, bacteria, Phytoplasmas, viruses, viroids and nematodes, which cause reductions in the quantity and quality of yield. Apart from the late blight fungus [Phytophthora infestans (Mont.) de Bary] viruses are the most important pathogens, with over 40 viruses and virus-like pathogens infecting cultivated potatoes in the field, among which Potato virus Y (PVY), Potato leaf roll virus (PLRV), Potato virus X (PVX), Potato virus A (PVA), Potato virus S (PVS) and Potato virus M (PVM) are some of the most important viruses in the world. In this review, their characteristics and types of resistance to them will be discussed.

The research was carried out, in the period 2002-2004 in order to determine the presence and distribution of potato viruses at 12 different locations and on 9 different potato varieties grown in Montenegro. The research included collecting of samples in seed potato crops and testing of six economically important potato viruses: Potato leaf roll virus (PLRV), Potato virus Y (PVY), Potato virus X (PVX), Potato virus S (PVS), Potato virus A (PVA) i Potato virus M (PVM). Using the direct enzyme-linked immunosorbent assay (DAS-ELISA) and commercial antisera specific for six potato viruses, it was found that PVY was the most frequent virus during the three-year research period. The second frequent virus was PVS, followed by PVA, PLRV, PVM and PVX. Single and mixed infections were detected, and the most prevalent were the single infections of PVY. Also, in the period 2002-2004, PVY had the highest distribution and the number of present viruses was different at different localities and on different potato varieties. Further investigations were related to detailed characterization of the most prevalent virus (PVY), which is at the same time economically the most important one. Serological characterization of PVY was performed utilizing DAS-ELISA kit with commercial monoclonal antibodies specific for detection of the three strain groups of PVY, and the two strain groups - necrotic (PVYN/PVYNTN) and common (PVYO), were identified. Necrotic strains were prevalent in 2002 and 2004, while in 2003 PVYO was the most frequent strain in virus population. The presence of stipple streak strain (PVYC) was not detected in any of the tested samples.
