I have 5 Krymsk1 rootstocks and 7 Marianna 2624 rootstocks coming in this spring. I was going to graft Veteran and Indian Free peach to the Krymsk1, but Olpea’s report on bud damage to Harrow Diamond on K1 has me thinking otherwise. So, has anyone actually grafted peaches onto Marianna 2624 before? I’ve heard conflicting reports on whether it works or not.
I have no information on grafting peach onto Mariana. However, I have a mature Mariana tree, and it’s my favorite plum. It’s not super productive, but it produces something every year, is a big tree which might be an issue with a peach scion, seems to be pretty stem canker resistant and has delicious cherry plum sized plums with blood plum flesh. Below is a pic of Mariana plums picked just slightly green being processed into jam. God bless.

I have an apricot on that 2624…it’s still young, but i hate how bad it has suckered. I plan on taking it out at some point and moving the cot to a different set of roots… I don’t like the location i put it in either.
I didn’t realize they produce any type of usable fruit, that is good to know. Five years ago, one of the first trees I planted was a tiny Mt. Royal plum that instantly got eaten down to the ground by a deer. It came back nicely, but it is probably the rootstock that regrew, and I don’t know what type of rootstock it was. I’ve been grafting other stuff onto it, but it looks like this year the original stock might produce some fruit. Maybe it will turn out to be something half-way decent.
The original Mariana was semi sterile being an F1 hybrid between Prunus munsii and a Maribel. That original cross happened well over 100 years ago. There have been a number of daughters (seedling varieties) which are not F1 hybrids so the genetics are better sorted out and tend to be fruitful even if the fruit is small. A number of these daughters have been selected for use as root stock due to superior qualities such as disease resistance. I got my Mariana due to the Jefferson plum that was on it not surviving the disease pressure of my climate. I have no earthly idea which Mariana it is. This past year I had a Green Gage to succumbed which came from a different nursery. Even thought I removed the stump, it has suckered quite profusely. I’ve moved one of the suckers to a neighboring lot owned by my cousins. Hopefully it’s a Mariana rootstock from a different seedling. If so when it matures, maybe it will serve as a pollination partner to my existing tree and improve its fruitfulness. By the way, my Mariana is entering its sixth year and is over 20 foot tall. They become big trees for plum trees which is probably why they are used as rootstock for European plums which also get to be big trees. God bless.

A rootstock chart that I think is probably pretty good (http://www.fowlernurseries.com/Rootstocks.htm) does not recommend Marianna for peach.
According to this paper, Marianna 2624 isn’t fully compatible with peaches/nectarines. At least with the one variety they tested with.
They tested with 20 trees on Marianna 2624 and all of them were considered category D:
http://hortsci.ashspublications.org/content/41/6/1389.full.pdf
Note that they also tested with St Julien GF 655-2, and it was fully compatible. It’s not as size controlling as Krymsk 1 though, as it had double the trunk circumference by year 2.
Of course, the one peach I have on K1 is extremely dwarfed. In the two years since it was grafted, it only grew about a foot. And I’ve needed to keep hacking back the rootstock growth below the graft. I’m thinking about just giving up and grafting a plum to it.
I did order some St Julien rootstocks from Raintree for peach grafting, though I’m not sure it is the same as what was used for the paper (“A” vs “GF 655-2”).

Ugh…that isn’t good to hear. Could it be graft incompatibility?
My peach (Old Mixon Free) on Krymsk1? Yes, I suspect it isn’t fully compatible. From the above paper, K1 gets the same result as Marianna 2624 (category D on 20 trees).

Maybe try an interstem with K1? I really don’t even know what i grafted to my k1 stock…i know i put some pluot (which should be fine) and maybe some cots…but i believe i put a few peach or nectarine too…i’ll have to see what takes whenever we start budding out here (could be a month at this rate).
I don’t mind the dwarfing effect…i’m use to container trees that put on little growth.
Some dwarfing is OK, but at this rate of growth it will be a few more years before it is big enough to support a single peach…
I have a few other K1 and also grafted apricots and plums onto them. The initial response of those was better, though I only grafted them this past spring.
I tried Saturn (one of the donuts) on apricot and it grew about a foot and died. I’ve though about trying apricot seedling (i have a bunch right now) under peach, but i’d use prunus americana interstem or something that can play with both… I think i budded some peach to pluot last summer so i’m interested how those work.
How well has your grafting peach scions/buds onto St. Julien rootstock done?
Thanks,
Frank

I’ve put two peach varieties, a nectarine, an apricot, and two almonds on Marianna 2624 (individually) with OK results. Can’t tell for the long run because they are still in pots, but the nectarine has made fruit. The apricot is in the ground and has put on strong growth. I also have a rootstock called Pumi that Raintree used long ago, and it’s been good with prunus in general, though not so compatible with plum. The Marianna has suckered, but not out of control.

Biringer nursery is grafting peaches on Mariana2624. Found several healthy large trees (Frost, Oregon Curl Free) for sale at Portland nursery.

Interesting, I didn’t know it’s compatible with peaches!

thats what I read everywhere, but this nursery seem to got a trick or method to make them compatible.

I grafted a apricot onto pear without knowing it was apricot. It survived for two springs. Couldn’t say they weren’t compatible. Please keep us updated in the future.

thats strange since pear and apricots are different genus altogether, I would expect the tree to reject the other species outright.
