    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?

    Well, I found another source that says "Trees of the cultivars 'Summerland Red MacIntosh" and "Harrold's Delicious" were quite susceptible ....while "Spartan" and "Goldern Delicious" proved relatively resisitant."

    I also found reference to

    ELLISONS ORANGE- somewhat canker prone.

    FORTUNE- ...European Canker, to which it is irritatingly suceptible.

    SPARTAN - It is somewhat prone to European canker. (which is contradicted by another source that says it is relatively resistant.)

    No doubt there is a good list somewhere.

    Hi there,
    I found the information you are looking for on the OSU web site http://plant-disease.ippc.orst.edu/disease.cfm?RecordID=47
    I also found some other sources but it is from Europe so it might not be accurate for the Pacific Northwest it is on the Chest of Books - http://chestofbooks.com/gardening-h...-Canker-Caused-By-Nectria-Galligena-Bres.html
    I hope that will help. I noticed that the Gravenstein is more susceptible on one site and more resistant on the other. I would am tempted to assume that OSU would have a geographical advantage over the European web site

    Haven't found any variety particularly resistant.
