Lon,
I did some more digging around the GRIN
database. There is a hybrid called “Appleberry” (X Sorbaronia sorbifolia)
developed by N. Stewart in New Brunswick. The database says “Fruits black, taste like an apple and
very sweet”. That sounds like it has potential as an edible. Material
is available for distribution from the repository in Corvallis.

Of the
bunch, only the Sorbopyrus (the so-called "Shipova") is edible.
The rest either don't have fruit, or it isn't palatable. The
Sorbaronia has intense red, almost black foliage. I have a
Crataegomespilus and it sets heavily, but the fruits are like pure hawthorn -
they won't "blet" like a medlar. They are edible, but not that
great unless you make jelly.
Most of these seem to be of European, possibly eastern
European origin. The Russians made all sorts of odd hybrids looking for
more fruits for cold climates.

I have not heard of Sorbus-Crataegus hybrids before. I checked the
ARS-Grin database and found a number of intergeneric hybrids of Sorbus with
other rose family ediblesŠ
X
Sorbocrataegus = Mountain Ash x Hawthorn
X
Sorbaronia = Mountain Ash x Aronia
X
Sorbomespilus = Mountain Ash x Medlar
X
Sorbopyrus = Mountain Ash x Pear
At
least one of these specimens is available for distribution from the national
repository system.
What
do you know of these hybrids (who produced them, where did they originate)?
Do any
of them have culinary potential?

This may help explain something that happened to me one time. I had a few
cuttings of a Sorbus-Crataegus hybrid I stored in the refrigerator and forgot.
When spring came, I found them and they had produced a ring of callus.
I treated them with Dip -n- Gro liquid rooting hormone and planted them.
I only had a couple, but they rooted and grew. The person I got
them from said that they had never been able to root cuttings previously, so
the method may be something to try on other things besides Prunus.

In the Autumn sixteen inch cuttings are taken from the parent plant. Basal
ends of the cuttings are Immersed in 100 ppm IBA as IBA Water Soluble Salts
dissolved in water for 6-12 hours.
Cuttings are then bundled in groups of 25. Bundles are wrapped in perforated
transparent plastic sheeting.
The wrapped packages are placed into crates which are piled to allow air
circulation.
The crates are left in cold storage at a temperature above freezing (33-35F)
for the Winter.
Ethylene generation is checked regularly as it could be toxic to the
cuttings.
During cold storage a callus ferrule forms around the lower end of the basal
end.
In the Spring the cuttings are planted in the open.
Hello all,
I have used the above basic method to propagate P. cerasifera with slight
modification and it works very well. I take 12 inch cuttings pencil size
about Nov. 1 (zone 5B), remove leaves, quick dip bottom 1/2 inch in Woods
Rooting Liquid, air dry until the liquid is dry (a few minutes). Now I bundle
(hand full size) these cuttings and place in 1 inch damp milled sphagnum in a
vertical position at about 60 degrees for two weeks. During this time the basel
end callouses. I then reopen the bundle insert a little more sphagnum along the
length of the bundle to retain moisture, but not wet, wrap entirely in heavy
plastic and store vertically positioned in the cooler at about 35 degrees. I
also store apples in this walk in cooler and haven't detected any degradation
of material. In early spring as soon as ground temp reaches about 60 degrees
they are placed in the growing beds, 6 inches deep and 6 inches above ground
level. At this time some of the cuttings will have already begun to root.
Will this work with cherries, don't know, haven't tried it.
