DETECTION OF PVY, PLRV AND PVX POTATO VIRUSES IN SOME REGIONS OF SERBIA

Abstract

During a one-year period, the testing of samples of seed potatoes from the territories of Moravica, Zlatibor, Raˇska and Maˇcva districts of the Republic of Serbia was carried out. The presence of the three most important viruses: PVY, PLRV and PVX, was determined using serological DAS-ELISA test. Out of all tested samples, 34.62% were positive for some of these viruses. The greatest frequency was shown by PVY virus (86.36%), and significantly lower frequencies were shown by PLRV (11.62%) and PVX (2.02%) of all infected samples. PVY was detected in all districts, PLRV in all except Maˇcva district, and PVX was detected in the Moravica district, only. The results obtained indicate that the virus diseases could be one of the reasons for the lower potato yield in Serbia compared to Europe. This imposes the need for the application of integrated protection of potatoes.
