Fruittree Rootstocks Holland BV selects existing rootstocks and seedlings from various crosses for replant disease tolerance. This has led to a number of potential rootstocks. Coming years, these will be further propagated on stool beds and selected. In addition to tolerance for replant disease, Fruittree Rootstocks Holland assesses the plants for other resistances and tolerances. Such as drought and frost tolerance.
Grafting the rootstock with commonly used varieties shows the growth of the combination of rootstock and fruit variety.
Fruittree Rootstocks Holland has prioritized the following selection criteria:
- Replant disease
- Poultry red mite tolerance
- Fruit tree cancer
- Storage and burnots
- Drought and frost tolerance
- Fire blight
