TL;DRAbstract

Breeding high quality apples combined with excellent agronomic features promotes
\nsustainable production systems. This approach includes durable genetic disease
\nresistance against scab (Venturia inaequalis), powdery mildew (Podosphaera
\nleucotricha) and fire blight (Erwinia amylovora). Glasshouse screening of advanced
\nselections and traditional cultivars with a shoot inoculation test for fire blight resistance
\nhighlighted considerable differences. We report on approaches for breeding new high
\nquality scab and mildew resistant and fire blight tolerant varieties including markerassisted
\nselection (MAS) and on promising advanced selections.
