Biological Mechanism & Horticultural Rules
Stone-fruit rootstock behavior varies across Prunus species, cultivars, viruses, soils, and climates. The tool provides conservative reviewed categories and refuses to infer a durable union from short-term callus alone.
Assumptions & Physical Constraints:
Use certified propagation material. WSU flags Krymsk 5 and 6 as sensitive to Prunus ringspot and prune dwarf viruses; this tool does not diagnose virus status.
Sweet Cherry + Gisela 5: WSU describes a precocious tree about half the size of Mazzard that may need support. Confirm the cultivar, site, and training system.

Frequently Asked Questions
Can I use Gisela cherry rootstock for peach?
No. Gisela rootstocks are selected for cherry systems and peach-on-Gisela is not treated as a dependable propagation combination. Do not infer durability from short-term callus.
