Cultivars with low susceptibility to scab (leaf and fruit). Apple cultivars of the JKI collection with scab rating scales 1 (no symptoms) and 2 (very low scab) in 2012 to 2013 are listed and additional data from experiments obtained in 1997 and 1999 and from 2006 to 2007 are supplemented. R genes indicated by the respective marker allele(s) from molecular analysis are given.
