There are two general types of resistance genes found in wheat: Race - specific genes confer a high - level of resistance to specific strains of leaf rust but can be easily overcome by genetic mutation in pathogen populations, while slow rusting (APR) resistance provides partial resistance to a broad spectrum of races, but is typically effective only at the adult stage of plant growth.
