I haven't tried ordering from them, but I it looks like they do have some for sale: https://www.incredibleseeds.ca/products/antonovka-apple-tree-seeds 

THank you for this. I've ordered a couple packs but needed more like 100 or so

Summerland has seed for antonovka, it is listed under their budwood drop down menu then click catalogue, and it is listed right at the bottom. The prices are listed on the budwood price page. Here is the link.https://www.summerlandvarieties.com/budwood/catalogue/

Thanks. I checked and they are sold out

Hmmm, to bad, I often look for rare seeds how about Sheffields? it looks like they have some and they do ship to Canada.

Would't these seeds be crossed with something else?

In the first link it says..

>>This is a great rootstock apple tree with fruit that is ideal for cooking. <<

That's total BS...seeds hardly ever come true to Cultivar! Most likely you'll get little ornamental apples. You could just pick some Siberian crab apple seeds from local trees..it wouldn't make much difference.

That's a really good point Konrad, that didn't even cross my mind. I wonder if is any chance the seeds come from a controlled cross, I would assume this would be difficult for a tree.

Antonovka seeds are one of only a few that run true from seed....apparently.

I learn something new everyday, https://permies.com/t/54818/true-ish-seed-apple-cultivars 

I also have read that is comes true from seed. It also looks like a pretty good apple.

I've been hearing for years.......hardly any Antonovka apples are the real thing anymore...been polluted down, so no, not true from seeds, perhaps close and mostly used for full size tree root stock...not something I'd do in a homegarden..especially for zone 8.

Not to change the topic Konrad but I think the UfoS says the same thing about wild plums, very hard to get one that hasn't been crossed at some point.

I guess that is why some of the siberian apple seedlings I order for rootstock have red leaves, they are crossed like all the rest. Time to save my own.

We can't believe everything on internet....

I've asked this question to my mentors..

From Dr. Ieuan Evans..

I`d be amazed if it grew true from seed. Oranges,
peaches, nectarines, lemons, apricots and dandelions grow 95% + true
from seed. Saskatoons 70%. Apples, pears plums cherries are all true
crosses as far as I know.

From Bernie

I heard its impossible for them to grow exactly true to type from seed.
But close enough to make a good rootstock. Don Siemens used to grow
seeds for Sprout Farms years ago and liked
them.

From Gabor Botar

Apple cultivars differ in the proportion of seedlings that physically
resemble the mother plant. Some, like the Antonovka most people talk
about, will have seedlings that often resemble the mother plant,
irrespective of pollen
source. (McIntosh apparently also has this tendency, with over half of
its seedlings resembling the mother plant in many respects.) I found
seedlings of 'Columbia' to be useful as reliably similar hardy
rootstocks. Physically similar does not mean genetically
identical, unless the seeds were produced apomictically. 'Antonovka' is
actually a cluster of related Malus lines, some of which may indeed be
apomictic...I do not know the details. Short answer : chances are good
that your seedlings will behave much as expected
if used as rootstocks, but fruit quality is less likely to be as
predictable.

From a US friend..breeder

Well it would seem unlikely that, if grown from seed, the strain could
have been kept that pure. Certainly some of the generations would have
been from stray pollen of other apples. Even if Antonovka apples were
grown only where the seeds were made, and no
pollen was carried in by insects from other types (fat chance of that
over many generations of unknown breeding), seedling variability would
guarantee some differences in the resulting supposed Antonovka apples.
Throw in stray pollen or uncontrolled crosses
over the generations and probably you have something that somebody
claims is the original Antonovka, or may resemble it, but probably is
not and cannot be unless it was clonally propagated. IMO one can say
things come "fairly true" from seed, but this does
not make a pure strain which is completely stable through many
generations. You might have someting more like a Landrace variety,
although perhaps that term is different. Even the six or eight
generations recommended to come up with a supposedly pure inbred
line is only an approximation of something, and various genotypes are
still going to be hidden in there, though not nearly as often expressed
in the phenotype. Even clonally propagated material can change
occassionally... ie. somaclonal variation, sport mutations.
I may sound like I am trying to talk like I think I am a plant
breeder... but I will admit I am only of the amateur sort. So run this
question by a real fruit tree breeder with credentials. haha.

Here... maybe you can pay thirty bucks or so and get something out of a download of this paper. I'm too cheap do it myself.

Effect of mutational variability on characteristics and properties of common Antonovka apples [1974]

Kolontaev, V.M.

From a Austrian friend...

1) one might have to check if Antonovka (there are several sports of it!) is self fertile!

2) if so it might have to be planted far away from any other flowering apple tree = which is quite unlikely to get pollinated!??

3) Apomictic plants like many Amelanchiers are can produce strains
which come quite true from seed but there is also subtle change over the
generations also due to mutations and genetic rearrangements (crossing
over? in plants??

4 You get even bud mutations if you propagate clonally! Moreover
some epigenetics might also play a role in plants which are grown from
cuttings again from cuttings. It is known that their leaf shape can
change due to effects I don ´t understand.

Antonovka is a well known rootstock for that purpose yes. Here it
did not do as well as I thought and I am working with Bittenfelder now.
Voles seem to like it a lot! They seem to produce larger trees and good
sized apples (influence of the rootstock).
worth a try.

There are different strains of Antonovkas. I grow Antonovka 500g
and Antonovka safranoje (which I got from FIN) - it is earlier ripening.
The Belarus guy on Youtube posted a few comments and a video on his
Antonovka strains!

Nice. Well done

Thank you for the clarification Konrad. Definitely not my area of experience. I’m learning about rose breeding, and my understanding when controlled cross is made (and pistils covered), the seedlings from one hip still vary; your info supports this.

From Thean Pheh....breeder

Ananros is one of the better known seedling of Antonovka. See the big differences both in size and qualities! I have used open pollinated Antonovka seedlings before as rootstock and I'm not impressed - too much variations in hardiness.

Peace

Thean

Globell..what is your intention with the seeds...grow them out or rootstock?

Yes. Rootstock. We live by a creek and want them to feed from the water table without irrigation (once established). We like the taproot and the soil on that size of he yard isn't grand as it's fill we are remediating the soil for printing in one years time for five large trees

Suggestions in regards to antonovka?

Well...most of the island gets plenty of rain, think Antonovka roots would make them too large.

Perfect. I may also use an interstem

This uses a number in the name as though a clone from a series is being used as root-stock.
