Hybrid oaks

22 years ago

Dear Hybrid Masters,

I've been looking for info on oak hybrids for a while on the Net with very limited success.

I could found several foot-note-like remarks as "hybridization within oak sections is generaly easy" and alike but I was unable to find exact data.

Could someone help me with a list of the latin names of quercus species that can form hybrids with others within the respective section?

Or could someone post a URL where I can found this info?

A similar list would do fine e.g.:

Q. alba x Q. macrocarpa = result (x Q. obscuriformis or any)

Thanks in advance,

Levente

Say you are looking to see whether a tree is a white oak or a red oak. Identification is complicated by the occurrence of hybrids, which often have quite variable leaves. All species are inclined to hybridize except that white oaks do not hybridize with red oaks. Since many hybrids lack fruit, it is a good idea to turn to neighboring trees with acorns. When these fertile trees have been named it is often possible to recognize a hybrid in respect to the two parents that are involved. Hybrids can often be recognized as hybrids if they cannot be "keyed out" and/or do not match any photographs and descriptions.

Here is a partial list of native hybrid oaks:

Quercus x anceps Fagaceae Hybrid oak tree native -
Quercus x bebbiana Fagaceae Hybrid oak tree native -
Quercus x bushii Fagaceae Hybrid oak tree native -
Quercus x deamii Fagaceae Hybrid oak tree native -
Quercus x exacta Fagaceae Hybrid oak tree native -
Quercus x fallax Fagaceae Hybrid oak tree native -
Quercus x fernowii Fagaceae Hybrid oak tree native -
Quercus x filialis Fagaceae Hybrid oak tree native -
Quercus x hillii Fagaceae Hybrid oak tree native -
Quercus x humidicola Fagaceae Hybrid oak tree native -
Quercus x jackiana Fagaceae Hybrid oak tree native -
Quercus x ludoviciana Fagaceae Hybrid oak tree native -
Quercus x palmeriana Fagaceae Hybrid oak tree native -
Quercus x runcinata Fagaceae Hybrid oak tree native -
Quercus x saulii Fagaceae Hybrid oak tree native -
Quercus x schochiana Fagaceae Hybrid oak tree native -
Quercus x schuettei Fagaceae Hybrid oak tree native -
Quercus x tridentata

http://waynesword.palomar.edu/hybrids1.htm If you go to this site there are some great pictures of hybrid oaks along with some other interesting plant hybrids. You will find the oak photos toward the middle of the site pages.

I used to roam through the Bluff Woods Forest in Missouri and pick out hybrids between the black oaks and the red oaks. I had the description of each species with me to identify the hybrids. It was a lot of fun.

When I worked for the Forest Service in Northern Wisconsin some of my colleagues worked with oaks and their goal was to improve red oak. One of their frustrations was that pin and red oak easily crossed. Red oak acorns are generally larger than pin oak. For their experiments they would get acorn collections and through seives separate out different sized acorns and use the larger ones because they are assumed to have primarily red oak genes.

What oaks are you planning on crossing? Too bad they seem so difficult to root cuttings from and clone superior selections. These researchers were able to have some success rooting cuttings from relatively young trees under certain conditions. I'm not sure how much grafting work has been done for propagation of superior clones.

Tom--and the rest of my advisers here: I forgot to mention that I have some hickories. I have two shellbark, pignut, mockernut, and shagbark. I have two shellbark because I planted the first one on a bit of a ridge where the soil is more shallow, I subsequently read that shellbark hickory is generally a bottomland species. In the spring the buds get very large, and just before and after break, the bud scales, or whatever they are called, grow and become red, so the tree seems to be covered with flowers--beautiful. I have some hickory on my timberland, and one shagbark, especially, is absolutely gorgeous. Looking at this tree, one could imagine it is the most beautiful tree in the world. One problem here is they grow very, very slowly. I also have 2 hiccan hybrids, which are supposed to grow extremely fast, but for me they are almost not growing, even after 5 years, and I have three pecans, also of the genus Carya, of course. They are also growing very slow in my environment here. I love hickories, but here--what's the old saying? "I should live so long!" I did some more research on American beech--based on what I can find out, maybe my initial idea of not bothering with it here is correct. They really, really don't like droughts, and don't like exposed sites. I never, never see any in the woods around here, and I am not sure I can point to a single one in Winchester. Beautiful trees, but I am afraid not for here. Well, I am still looking for ideas. I know it is a sin in the minds of many in these forums, but I may just prune up a Norway spruce or two for shade trees, and/or white pine. But so far the oaks are the best I have. I mentioned the white and swamp white oaks, but the two largest are Shummard oaks--they thrive here. Oh, and I have cottonwoods. They are not spreading yet, so not much shade. Where I grew up--from age 5 to 15, the primary tree for shade and general enjoyment was a cottonwood. Gorgeous!! I have a Siouxland cultivar of eastern cottonwood. In the ground 5 years, 20 feet tall, and looking like it may be the star of all the 120 or so kinds of trees I have here!! Wonderful large leaves, rich green, glossy, and so far this tree is acting like it is more drought resistant than my other cottonwoods. --spruce

Hybrid Oak?

Yea..this is a mighty nice oak tree northspruce. My estimate 50 plus years...perhaps 75? I have some now about 15 years and I see in spring when they flower that honey bees are on them, so I'm extremely pleased with this,...I never knew this would happen when planted.

has anyone hybridized oaks with non-local pollen?
Q

Camellia hybridizers have been collecting, storing and trading pollen for ages. Especially when trying to hybridize species which bloom at different times -- spring and fall bloomers -- or are growing in other parts of the world. Collecting oak pollen shouldn't be too hard, but succesful storage or preservation of viable pollen might be. Perhaps with refrigeration viability can be prolonged. Have you ever hybridized oaks? What system of baggy or netting would you use to prevent accidental pollenation? Apparently self pollination is rare among oaks (?), so that would negate the necessity of removing catkins.

Levente,
Order up a catalog from these folks:

OIKOS Tree Crops
P.O. Box 19425
Kalamazoo MI 49019-0425
Phone: (616) 624-6233
Fax: (616) 624-4019

They specialize in generating all types of really cool oak hybrids and they share what the parents were for each type.

There's a great chapter on hybridizing your own oaks, in the book "Breeding Ornamental Plants", Timber Press.
I love this book, it also has chapters for several other genera.

Levente,
I'll second the motion for OIKOS - I've gotten a number of my F2 hybrid seedlings from them.

Another source of hybrid acorns is Starhill Forest Arboretum (email strhlfrst@aol.com for a catalog), though their usualy cut-off date for order placement is 15 Aug. You might be able to get them to grant an extension, or at least place you on the mailing list for next year.

I got a few new hybrid acorns from a friend & fellow IOS member who was able to attend the 2000 IOS Conference in Asheville, NC last fall. Check out the IOS website, linked below, and consider joining, if you're not already a member.

Currently, I have the following hybrids growing in my collection:

Q.macrocarpaXrobur - seedlings & grafted "McDaniel" selection
Q.macrocarpaXbicolor
Q.macrocarpaXmichauxii
Q.macrocarpaXmuehlenbergii
Q.albaXrobur
Q.roburXmontana(prinus)
Q.bicolorXrobur
Q.lyrataXvirginiana
Q.virginianaXturbinella

There may be others in the nursery, but these are all I can think of, off the top of my head.

Here is a link that might be useful: International Oak Society

Does anyone have a web address for Oinkos.
Also a couple months ago in Mother Earth News,
I saw an add for someone carrying hybrid oaks,
but I misplace the web link.

I stumbled into this looking for information on white vs red oak family. Now I'm mostly practicing thread necromancy. Its neat to read a thread which is older than people who cam drive now. Thanks for saving these 1's and 0's Houzz.
