I have recently received budwood of this cross and grafted it on Poncirus. This is actually only my second succesful graft.
However, I can find very little information on it and would be grateful if anyone could share what they know.

I have it, got the wood from Robert (Zitrusgaertner) in 2012. On own roots it is not enough resistant and grows rather slowly.
In 2013 I low grafted it on poncirus, it is in ground without protection since 2014, no winter damage up to now.
It comes probably from a free pollinated immature seedling of initial hybrid , since only a small number of leaves are trifoliate.

Approximately 1.5m high, but has not flowered yet.
-
At least it is quite hardy, that's a good start:-).
Do you know where the original cross came from?
-
I really do not know, most probably actual budwood is from Andi Voss plant.

In a literature there is description of tetraploid hybrid obtained by somatic cell hybridization.
-
A few days ago, I emailed Andi Voss but haven't got a reply yet. I am curious whether his plant has flowered and how hardy it is up there compared to your place, Ilya.
-
How thick are the leaves?
University of Florida created a tetraploid plant by combining protoplasts of Hamlin and Flying Dragon.

-
It is probably another variety, since tetraploid somatic hybrid has only trifoliate leaves

I can't really tell how thick the leaves are since they have not yet hardened fully.
-
Hamlin x FD from Andreas Voss is a seedling of this hybrid. He got seeds from Riverside.
-
Was it flowering at his garden?
-
Itīs been some years I visited his garden. I really can`t remember.

I've just received a response from Andreas. Last year, his plant flowered for the first time. Unfortunately, there are no flowers this year. Fruit quality will remain a mystery for at least another year.
However, he said it is extremely coldhardy and unscathed after -12C. (10.4-F). I guess that is quite promising even if the fruit should not turn out to be the best tasting. A small step into the right direction..?
-
I grew HaminXFD from seed but don't remember who gave it to me. Maybe Andi. I lost the plant years ago. Nice that it still lives with you, Ilya!
-
Mikke, Roberto, Ilya it means that we have two different FDxHamlin seedlings in Europę. One is Ilya from seedling's Roberto and second from A Voss. Please correct me if I wrong.
What is origin the plants of A.Voss?
-
A.Voss received seeds from UCRiverside. There are probably several types around.
-
I have from you it means propably from A. Voss.
-
yes I`ve got mine from Andreas Voss. How are yours? Any pictures?
-
Andreas Voss once posted the seeds he received from the UCR on his website. If I remember correctly, there should be at least 12 different seedlings...
-
Has anybody ever had fruit from their plant? Haven't heard from Andreas since my above post from 2018.

My guess is that the seedlings of Andreas and Robert are similiar, both most probably of nucellar origin.

Ilya,
I am quite sure that my seeds came from Andi Voss. He shared what he had got from Riverside with some other people. One of them was me ;)
-
Interesting Discussion - but anyone with fruits, pictures ? Taste ? ;)
-
Finally this year there is one fruit hanging. I missed its flowers in the spring.

-
Nice Ilya, so we are curious to your taste test in a few months :D
-
Hamlin is the most cold hardy of the good juice oranges but a tangelo is slightly more cold hardy. That would be a good choice to use in further breeding.
-
Oh, excellent! Mine still has not flowered yet and I don't know of anybody else who has had flowers.
-
Thank you for photo 😯 Ilya.

Hello Ilya, Is this fruit already ripe?
-
Not really, but it is much larger now.
(https://i.vgy.me/NkNOd0.jpg)
(https://i.vgy.me/dnsomG.jpg)
We have not yet had any frost by now, will pick it in the beginning of December.
-
nice!
Did you get the tree from Bernhard Voss?
There are sedlings from Andreas Voss around. I wonder if yours is the same or a different one.
-
As mentioned above, I got the seedling's budwood from Robert .
-
We expect first night freeze this week, so I decided to harvest this fruit.
(https://i.postimg.cc/RWL6rV6V/20221204-103521.jpg) (https://postimg.cc/RWL6rV6V)
Still partly green, 177 grams of weight.
-
Do you know when have it showed first flower in this year? Was it bloom in spring or later?
-
No, I missed its flowering.
The season was extremely hot and dry, my other inground citruses are rather late this year, probably due to the lack of water.
-
How did the fruit taste, Ilya?
-
I decided to keep it inside for few weeks until it turns to yellow.
-
So, after a month in room the fruit is completely yellow.
(https://i.vgy.me/eMczf2.jpg)
No seeds, rather thick albedo, skin has lemony perfume and lost most of poncirus like odor.
(https://i.vgy.me/hXF2o0.jpg)
Fruit is easy to juice
(https://i.vgy.me/syfo1I.jpg)
Juice has "soar" smell, no poncirus aftertaste, 12° Brix, bitter acidic taste, very faint barely perceptible internal oils.

Ilya, did your HamlinXFD-Fruit get ripe?

Very interesting Ilya. Nice success.
How would you rank the taste within your frosthardy crosses and other frost hardy varieties of you including Morton ?
-
Morton is the best, practically no bitter taste. Thomasville is also fine, but small and is ripe only by spring.
-
Thanks Ilya, so glad that I have Morton in my garden - now it still has to bloom ;)
-
So it has normal leaves? The wild orange with a verbslight trifoliate taste has normal leaves but due to taste I think it's a trifoliate poncirus hybrid.
-
I'm thinking it's probably a Morton seedling. It has more seeds than Morton, huge number but Morton has a lot of seeds. Seems about the same otherwise. I took some seeds from it to grow. It's greening and other disease resistant. Not great fruit but edible decent.
-
Thank you, Ilya, for your description!
