Fruit Tree Rootstock
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.
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.
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.
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.
