Yellow Rust Virulence Frequency by Country

The Virulence Frequency by Country tool, developed by the University of Aarhus Denmark, displays the frequency of virulence to specific combinations of Yr genes in analysed samples over time for a selected country. Selection of any specific combination of Yr gene virulence by country is possible. Any new data incorporated into the underlying database will automatically be displayed on the graphs.

NB: These graphs do not represent absolute yellow rust Yr gene virulence frequencies at the country level; only sample frequencies are represented.
