✦ Synopsis

To find a fast and reliable test to assess resistance to Nectria galligena in apple, different methods of inoculation were compared using macroconidia of N. galligena and one-year-old cut shoots from mature trees of Cox's Orange Pippin, IVT 69078-19, James Grieve and Jonathan .

With the best inoculation method 11 genotypes were screened for resistance . Elstar, Golden Delicious, Jonathan and Lombart's Calville were highly resistant and the level of resistance of Ingrid marie, Gloster, Melrose, IVT 69078-19, Cox's Orange Pippin, James Grieve and Idared decreased in this order .

The best inoculation method proved to be simple, giving results within four to nine weeks after inoculation .
