VI International Scientific Agricultural Symposium "Agrosym 2015", Sarajevo, Bosna-Hersek, 15 - 18 Ekim 2015
Potato (Solanum tuberosum L.) is one of the most important agricultural crops of Turkey, having a history of nearly 150 years in the country. Potato virus Y (PVY) is one
of the most important agents causing potato crop losses worldwide. In the last decade, several strains of PVY have been differentiated. The strains cause different symptoms on
numerous commercial potato cultivars. In this study, we report a survey of PVY strains, performed on potatoes in 2015, in which 61 potato leaves and 20 weed samples were
screened from potato growing areas of Niğde, Nevşehir and Kayseri provinces in Turkey. The samples were tested by serological (ELISA) and molecular (Multiplex-RT-PCR)
methods. Strains were differentiated by using strain specific primers. A total of 40 potato samples were found infected with PVY strains, either in single or mixed infections.
Eighteen potato samples were contained PVYN:O and 18 were infected with PVYNTN strain. Three samples were exhibited mix infections with PVYO and PVYNTN and a
unique sample was found infected with PVYNTN+ PVYN:O. Twenty-one samples were reacted negative for PVY infection. Among the weed samples tested, 13 were found
infected with PVYNTN, 2 were infected with PVYNTN+N:O, and one sample was infected with PVYN:O strain. The present results revealed a high PVY incidence in surveyed areas.
The dominant strains of potatoes were PVYN:O and PVYNTN. The presence of PVYNTN and PVYN:O strains in tested weed samples is the first report for the weed species invaded
Turkish potato growing areas.
