Occurrence of cereal viruses on wheat in Tekirdag, Turkey.
A survey for the detection of barley yellow dwarf viruses (BYDV-PAV and BYDV-MAV), cereal yellow dwarf virus (CYDV-RPV), barley stripe mosaic virus (BSMV), wheat dwarf virus (WDV) and brome mosaic virus (BMV) was carried out during May 2003 covering seven cereal-growing counties of Tekirdag, Turkey. A total of 260 wheat samples with yellowing, stunting, or striping were collected from 26 wheat fields. These samples were tested for the presence of the six viruses by ELISA using polyclonal antisera. Serological tests showed that the tested viruses were present in Tekirdag, Turkey. Among the tested viruses, BYDV-MAV was the most commonly detected (25% of the 260 wheat samples), followed by BYDV-PAV (22.3%), WDV (16.5%), CYDV-RPV (8.5%), BMV (3.1%) and BSMV (1.5%). This study revealed the presence of six viruses in wheat fields in Tekirdag. BSMV and BMV are reported for the first time on wheat in Turkey.
