- •
We evaluate the durability of apple resistance to scab over eight years in orchard.
- •
We follow the level of aggressiveness of isolates of Venturia inaequalis.
- •
The isolates sampled on apple genotypes with quantitative resistance are aggressive.
- •
The erosion of the quantitative resistance based on the specific QTL T1 is slow.
- •
The QTL T1 is promising for the sustainable control of scab disease.
