Cereal rust control in Australia has been a long term nationally co-ordinated program aimed at achieving comprehensive resistance rather than a mosaic of resistant and susceptible (especially very susceptible) cultivars. Annual rust surveys are undertaken to monitor pathogenic variability, to provide early warning and confirmation of losses in resistance resulting from new virulences, and to obtain and use new pathotypes in breeding for resistance. An ongoing search for new sources of resistance provides germplasm for the future. Suspected novel genetic material is subjected to genetic analysis to identify the genes responsible and to establish their limitations for resistance breeding. A centralised screening service is available to all Australian wheat breeders and currently-effective and potentially new genes are made available through an ongoing germplasm enhancement program where breeders nominate the recurrent parents and the rust laboratory provides the resistance resources. The expected rust responses and the resistance genes involved are usually known at the time of cultivar release.
