| Abstract: | Key findings • Yearly screening is required to quantify and monitor the reaction of current and new varieties to diseases of economic importance. • Natural changes in virulence occur in pathogen populations or when exotic pathotypes are introduced to Australia. These can affect host plant (variety) resistance ratings in both cereal and broadleaf crops. • Five wheat stripe rust pathotypes of significance were detected in the NSW cropping regions during 2020; four were present in NSW Department of Primary Industries (NSW DPI) stripe rust nurseries. • Host resistance can vary significantly depending on the stripe rust pathotypes present. • Growers and advisers are kept up to date with latest resistance ratings each year through nationally co-ordinated National Variety Trials (NVT) pathology trials across a wide range of crops and diseases. |
