Incidence of cereal viruses on winter barley grown in Tekirdağ, Turkey.
A survey for detection of barley yellow dwarf viruses (BYDV-PAV, BYDV-MAV), cereal yellow dwarf virus (CYDV), barley stripe mosaic virus (BSMV), brome mosaic virus (BMV) and barley yellow mosaic virus (BaYMV) was carried out during May 2003 in 9 barley-growing counties (Tekirdağ-center, Çorlu, Çerkezköy, Hayrabolu, Saray, Șarköy, Malkara, Muratlı, Marmara Ereğlisi) of Tekirdağ, Turkey. Some 290 samples with yellowing, stunting or striping were collected from the barley fields. These samples were tested for the presence of 7 viruses by ELISA using polyclonal antisera. Serological tests showed that the 7 tested viruses were present in barley fields in Tekirdağ, Turkey. Among the viruses detected, BYDV-PAV was the most common, being detected in 65 out of 290 samples (22.41%), followed by BYDV-MAV (17.93%), WDV (16.20%), BaYMV (13.44%), BMV and CYDV (7.93%) and BSMV (3.10%). This is the first report for the presence of BaYMV, BMV and BSMV in cereals in Turkey.
