Fruit Tree Rootstocks
Most fruiting stock we offer is "Certified virus free".
This stock is produced from virus indexed scion trees, virus certified
root stocks and is apparently free from known virus diseases within accepted
standards established by the Oregon State Department of Agriculture.
What this means to the home or commercial fruit grower is a much healthier
tree. This tree will produce larger yields of superior quality
fruit. This tree will grow faster, live longer and will
minimize many fruit tree diseases.
Apple Rootstocks SEEDLING This is "standard" size stock that produces vigorous
and well-anchored trees. Generally seedling-rooted trees are slower to
come into bearing than those on the clonal rootstocks but perform very
well in less vigorous growing conditions.
EMLA III This stock produces trees 75 percent the size of seedling and
about as well anchored. In non-irrigated soils it is somewhat tolerant
to drought. Trees on EMLA III, in combination with spur varieties of red
delicious, produce a tree of approximately ½ to 2/3 the size of
standard stock. Resists woolly aphid and collar rot.
EMLA 106 Trees on this stock are similar in size to those on EMLA III,
but due to heavier cropping, EMLA 106 bearing trees may be a bit smaller.
EMLA 106 is well anchored and non-suckering. It is a productive rootstock
in situations where collar rot, cold or drought are not prevalent.
EMLA 7/M7A Trees on EMLA 7/M7A will grow to slightly over half the size
of trees on seedling. The trees are fairly well anchored and cropping
is early and heavy. Requires well drained soil.
EMLA 26 This stock has slightly less vigor than EMLA 7A and is better
anchored. Trees on EMLA 26 come into bearing early and remain productive
under good culture. We recommend tree support during the early years.
EMLA 26 is recommended for very close plantings and has the same hardiness
as seedling.
MARK (MAC-9) Bred at Michigan State University with M-9 as mother parent.
Will attain the approximate size of EMLA 26 and will be strongly anchored
and free standing. Desirable orchard qualities are early flowering, heavy
production, free standing, persistence to suckering and tolerance to cold
temperature.
EMLA 27 Trees dwarfed between 6' to 10', with pruning less. Ideal for
small spaces, container planting, hedging or espalier. Young trees need
staking.
Pear Rootstocks
DOMESTIC SEEDLING PEAR The most widely planted pear rootstock, typically
produces a vigorous tree with strong, well-anchored roots. Tolerates a
wide range of soil conditions, moisture content and texture. Winter hardy.
WINTER NELLIS This seedling is slightly more vigorous than Domestic Seedling
Pear. Produces vigorous and well-anchored trees and is slightly more winter
hardy.
OLD HOME FARMINGDALE #97 A clonal selection of Domestic Seedling Pear
that produces a vigorous, full-sized tree 10 percent larger than that
of Seedling. Highly resistant to pear decline and fire blight.
BETULAEFOLIA For Asian pears. Vigorous, tolerates most soils including
alkaline.
OLD HOME FARMINGDALE #333 Developed for its ability to promote early and
heavy fruit production. Yields a semi-dwarf tree, 70 percent the size
of Domestic Seedling. Resistant to pear decline and fire blight. The best
dwarfing root for pears.
Stone Fruit Rootstock (Apricot, Peach, Plum, Prune) CITATION Nectarines and peaches dwarfed to 8' to 14', apricots and plums
3/4 of standard. Cropping is early. Tolerates wet soil. Rather new rootstock.
MYROBOLAN SEEDLING This rootstock and selections from it are widely used
for European plum varieties. It is compatible with a wide range of cultivars,
and particularly adaptable to heavier soils. Resistant to root-knot nematode.
LOVELL SEEDLING Lovell has proved to be a very dependable standard peach
rootstock. It provides a long-lived tree and gives a high degree of disease
resistance. This is especially true in the South and Eastern states, and
on replanted peach sites.
NEMAGUARD SEEDLING Vigorous, hardy, very nematode resistant. Outstanding
for well drained soil. Will work in heavy soils.
MARIANNA The most tolerant of wet soils yet shallow rooted. Resistant
to oak root fungus and root knot nematode. Somewhat dwarfing.
PUMISELECT A hardy very dwarfing rootstock from Germany. Pumiselect is very dwarfing and early bearing awith a superior yield. Cold Tolerant.
ST. JULIAN A This clonal rootstock was developed many years ago by East
Malling Research Station, England, as a semi-dwarf rootstock for a tree
smaller than standard. It is compatible with all varieties of prunus trees
by EM. It is winter hardy, being the only plum stock surviving the November
10, 1955 freeze in Oregon. Slightly dwarfing.
SIBERIAN C Semi-dwarfing rootstock with medium level of vigor resulting
in a tree that is approximately 75 percent of seedling.
Cherry Rootstock
MAZZARD SEEDLING Mazzard is a wild cherry rootstock best suited for sweet
cherry and tart cherry planted in heavier soil types. It makes a bigger
tree than Prunus Mahaleb. More tolerant of wet soils and more compatible
with various sweet cherry varieties. Especially well anchored. Quite hardy
but not as hardy as Mahaleb. Resists root knot nematode and oak root fungus.
MAHALEB SEEDLING Standard rootstock of Montmorency cherries. Hardier
than Mazzard, makes a smaller tree. More tolerant of drought and sandy
soils but less tolerant of wet conditions. Hardy, well anchored and widely
adaptable. Resists crown gall, bacterial canker, and some nematodes.
GM 61 Dwarfing rootstock for sweet cherries. Produces a tree approximately
½ standard size. Produces early and heavy cropping. Looks to be
the best true dwarf cherry rootstock.
