Hi Does anyone know of a source (website, book, newsletter, etc.) that identifies apple varieties that are least susceptible to european canker (Nectria Canker, Nectria galligena)? I found one source that says "can be a problem on varieties with enlarged terminal fruiting spurs, such as Rome Beauty and Jerseyred." And, I found another source that says "Complete resistance to the pathogen in apple is not known." But are there cultivars that are less susceptible?
