choice for wet and heavy soils. Mazzard is the most popular cherry
rootstock grown in North America. It is generally more vigorous
than Mahaleb, especially in poorer soils.

cv.) U.S.P.P. #9622
A popular introduction in Germany, this rootstock
produces a very precocious tree approximately half the size of trees
grown on Mazzard rootstock. It produces an open, spreading tree
with wide angles. It is quite virus tolerant and does well in heavy
soil. Trees grown on Gisela® 5 may need to be supported. Some
suckering may occur depending on growing conditions. It is very
hardy and produces well. It is compatible with most varieties. It
has shown good results in Washington State.

(148-1
cv.) U.S.P.P. #8954
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.

|
(195-2
cv.) U.S.P.P. #9631
A precocious, semi-dwarf cherry rootstock,
yielding a tree about 60% of one grown on Mazzard. Produces a tree
that is spreading and open. Resists suckering, is well anchored
but may require support.
