APPLICATION OF ELISA TEST IN THE IDENTIFICATION OF VIRUSES IN SOME POTATO CULTIVARS

In laboratory and field condition there were undertaken studies in order to identify virus diseases on three different potato cultivars mainly cultivated in Kovoso: ‘Kondor’, ‘Desiree’ and ‘Sirius’. For this purpose there were collected leaves from three levels of randomly selected potato plants; in the bottom, middle and the top of the plant. Samples of leaves were collected weekly then analysed by using Enzyme-linked immunosorbent assay (ELISA – test). Six types of viruses which cause disease on potato cultivars: PVY, PLRV, PVX, PVA, PVS, and PVM were identified. Disease frequency on potato cultivars was different. The most dominant viruses were PLRV with 27% and PVY with 24%. Other identified viruses on potato cultivars were present in less percentage.
