nematodes. Most common rootstock for almonds and peaches in the San Joaquin
Valley.
Marianna
26-24: Shallow roots.
Good vigor, although tends to slightly dwarf trees. Wide range of soil and moisture
types. Common for heavy soils that tend to be wet. Heavy suckering. Compatibility
concerns with almonds.

St.Julian
A: Good anchorage
& excellent vigor. Can tolerate wet feet as well as drought conditions.
Produces a tree that grows to be 80 to 85% the size of a standard tree.
Mazzard:
Excellent anchorage. Many shallow roots may become injured by deep cultivation
and drought. Sandy loam to loam. More tolerant of heavy soils. Makes a very
large tree. Cold hardy. Has root suckers. Common rootstock for cherry trees
in Washington State.
Mahaleb:
Excellent anchorage. Deeper roots than Mazzard. Good vigor. Light sandy loam
cannot tolerate poor drainage or heavy soils. Trees may be slightly smaller,
comes into bearing sooner, and heavier fruit set than Mazzard.
Emla-Colt:
Good anchorage and vigor. Heavier soils okay. Clay loam. Very vigorous, smaller
than Mazzard. Not cold hardy.
Lovell:
Good anchorage & vigor. Prefers well drained loam. Sensitive to wet feet
or heavy soils. Very little suckering.
Northern
California Black:
Deep rooting anchorage. Well drained sensitive to calcarious and saline soils.
Less susceptible to crown gall.
Paradox:
Deep rooting anchorage. Well drained sensitive to calcarious and saline soils.
Tolerates moisture better than Black. Tends to be more vigorous than Black,
common for heavy soils that tend to be wet. Very susceptible to crown gall.
Emla-7:
60% of standard apple seedling. Good anchorage. May need support in early years.
Performs better on deep fertile loam soils. Does not do well in light sandy
soils.
Emla-26:
45% of standard apple seedling. Usually needs support. Okay in all but badly
drained and light dry soils. Produces better quality fruit than Emla-7. Precocious.
Not as hardy as Emla-7. Shallow rooted, subject to drought stress.
Lovell:
Good anchorage & vigor. Prefers well drained loam. Sensitive to wet feet
or heavy soils. Very little suckering.
Marianna
26-24: Shallow roots.
Good vigor, although tends to slightly dwarf trees. Wide range of soil and moisture
types. Common for heavy soils that tend to be wet. Heavy suckering.
Marianna
26-24: Shallow roots.
Good vigor, although tends to slightly dwarf trees. Wide range of soil and moisture
types. Common for heavy soils that tend to be wet. Heavy suckering.
Myro
29-C: Roots tend to
be intermediate depth, good vigor. Medium to heavy soil. Wide range of soil
and moisture types. Less suckering than Marianna 26-24. Susceptible to Bacterial
canker
Myrobalan:
Excellent anchorage and good vigor. Light to heavy soils. Wide range of adaptability.
Susceptible to prune brownline. Slightly larger tree than Myro 29-C and Marianna
26-24.
M40
(Improved Marianna):
(USPP # 11,403) It has been observed that Marianna M40 has good wet soil tolerance,
with the potential for better anchorage and reduced sucker production. The M40
may eventually displace 26-24 and other plum rootstocks.
Lovell:
Good anchorage & vigor. Prefers well drained loam. Sensitive to wet feet
or heavy soils. Very little suckering.
Betulaefolia:
Excellent anchorage, extremely vigorous. Very adaptable to a wide range of soil
types. Susceptible to lime induced chlorosis. Good compatibility with most pear
varieties. A good rootstock for Asian Pears.
OHXF-87:
Semi-vigorous. Considered a semi-dwarf tree. Tolerant to blight and decline.
OHXF-97:
Good anchorage & vigor. Induced early heavy production. Resistant to pear
decline and fireblight. It is a superior rootstock for vigorous pear trees.
Hardy and resilient to cold.
Province
Quince BA 29C:
Good anchorage & vigor. Induced early heavy production. Resistant to pear
decline and fireblight. It is a superior rootstock for vigorous pear trees.
Hardy and resilient to cold.
Winter
Nelis: Excellent
anchorage & vigor. Does well in most soil types. Moderate growth in dry,
shallow soils. Uniform growth characteristics. Not a good rootstock for all
but the most vigorous Asian Pears.
