Yellow dwarf viruses (YDVs) are responsible for the economically significant disease that affects cereal crops worldwide,
reducing harves ted yield and quality of grains. These virus diseases on cereals have been prevailed and caused yellowing,
dwarfing, reddening, and the reduction of grain yield on cultivated cereals since 1999 in the Trakya region of Turkey.
This s tudy was conducted to inves tigate the presence of YDVs on rice and competitive weeds as barnyard grass
Echinochloa crusgalli (L.) P. Beauv, Johnson grass Sorghum halepense (L.) Pers. and common reed Phragmites aus trialis
(Cav.) Trin ex. S teudel in the Trakya region of Turkey. For this purpose, 120 symptomatic rice leaves and 18 weed
leaf samples were collected from the rice fields in Trakya. A total of 138 symptomatic leaf samples were tes ted by
DAS-ELISA and RT-PCR methods for the diagnoses of Barley yellow dwarf virus-PAV (BYDV-PAV), Barley yellow
dwarf virus-MAV (BYDV-MAV) and Cereal yellow dwarf virus-RPV (CYDV-RPV). The screening tes t results revealed
that 26 out of 138 leaf samples had CYDV-RPV, 5 of them infected with BYDV-PAV, and 10 leaf samples were found
infected with a mixture of CYDV-RPV+BYDV-PAV. Thus, 41 out of 138 leaf samples at the rate, 30% were found
infected with BYDV-PAV and CYDV-RPV. None of the samples had BYDV-MAV. To our knowledge, this is the firs t
report of BYDV-PAV and CYDV-RPV in the mos t important rice-growing areas of Turkey
