Abstract
Transgressive segregation has produced oat lines possessing higher levels of barley yellow dwarf virus (BYDV) tolerance than were previously available. Even with inoculation at the earliest growth stages, some oat lines now display a level of tolerance approaching that of Ethiopian barleys possessing the Yd2 gene.
