Barley yellow dwarf virus (BYDV) was detected in perennial ryegrass cultivars examined from three sites in south‐western Victoria (Balmoral, Mininera and Hamilton); the frequency of BYDV infection varied with cultivar. PAV‐related isolates were prevalent at all sites, but the incidence of MAV‐ and RPV‐related isolates varied with the site and cultivar. The PAV‐related isolate was less frequent in cv. Ellett than in cv. Victorian at all sites. The implications for the epidemiology of the disease and its agronomic importance in Victoria are discussed.
