Quince rust is a fungus disease caused by Gymnosporangium clavipes. The fungus infects fruit, but not leaves, of most apple cultivars. It infects both fruit and leaves of hawthorn. This table lists the quince rust susceptibility of numerous apple cultivars.

zR = resistant. Control needed only under high disease pressure.
S = susceptible. Control usually needed where disease is prevalent.
HS = highly susceptible. Control always needed where disease is prevalent. These cultivars should receive first priority when control is required.
