Abstract

Winter cereal viruses can cause significant crop losses; however, detailed knowledge of their occurrence in New South Wales, Australia is very limited. This paper reports on the occurrence of Wheat streak mosaic virus (WSMV), Wheat mosaic virus (WMoV), Barley yellow dwarf virus (BYDV), Cereal yellow dwarf virus (CYDV), and their serotypes between 2006 and 2014. Detection of WMoV is confirmed in eastern Australia for the first time. The BYDV and CYDV 2014 epidemic is examined in detail using 139 samples of wheat, barley, and oat surveyed from southern New South Wales. The presence of virus was determined using enzyme-linked immunosorbent assays. The results reveal a high frequency of the serotype Barley yellow dwarf virus - MAV as a single infection present in 27% of samples relative to Barley yellow dwarf virus - PAV in 19% and CYDV in 14%. Clear differences emerged in the infection of different winter cereal species by serotypes of BYDV and CYDV. These results are contrasted to other Australian and international studies.
