Stripe rust pathotype ‘Jackie
Yr27’ detected for the first time
A single sample of stripe rust from northeast Victoria was
confirmed as the first Australian pathotype with virulence for
the Yr27 resistance. The gene is present in several commercial
varieties and these will now be under a degree of uncertainty
until we can determine the expected field responses. The
evidence indicates that the new pathotype, designated the
‘Jackie Yr27’ pathotype, arose as a single mutation derivative
from the ‘Jackie’ pathotype.
