Cereal rust pathotypes (aka races or strains) are isolates of rust that differ in their ability to overcome resistance genes in cereal varieties. Pathotypes are identified by using a sample of rust from a cereal crop to infect a set of cereal varieties (“differentials”) – each carrying a known resistance gene – and determining which resistance genes are overcome and which are not.
