A semi-dwarf rootstock that produces a tree slightly smaller than Mazzard, roughly 80 to 90 percent. A good substitute for Mazzard, Gisela® 6 is well suited for heavy soil types. The tree structure is very open and round. Very precocious despite its vigor. It appears tolerant to many cherry viruses and is not prone to suckering. Anchors well, but may need support, especially in the first fruiting years because of its precocious nature.
