Thomasville citrangequat seedling again:



It might turn out to have non-trifoliate foliage.

this came from a seed from a fruit that Eyeckr sent me
The fruit actually tasted better than I was expecting, I didn't really seem to detect any trifoliate aftertaste, and it was a nice size fruit, there was only one seed in the fruit. The rind was maybe only a little less edible than calamondin.

Referring to rooting cuttings, the goal is to provide a relatively cool humid environment for the upper stem and foliage, while providing heat to the buried lower stem, so as to allow the energy reserves in the cutting to be directed to root formation rather than new foliage formation. When a plant has top growth removed, it directs it's effort toward restoring the balance by sending out vigorous new shoots. Likewise, it's important to assist the plant in it's natural attempt to replace the balance between roots and foliage when the cutting is severed from the mother plant. Only when this balance has been restored should the plant be encouraged to send out new foliage. Almost all horticultural activities function more smoothly when done in concert with the plants natural processes.

Here is an update on my dunstan citrumelo x ixs seedlings. Each one start to look different. This might be normal for f2 hybrids.
What is the experts opinion?

Variation is to be expected in zygotic F2 populations. It's an expression of the recombination of the genetic material in the F1 hybrids. Resessive traits that were not expressed in the F1 can now be expressed. An example would be F1 trifoliate plants producing F2 unifoliate progeny.

Only the seedlings of this fruit that was cross pollinated are different from eachother. All the other dunstan seedllings from two other fruits look the same.

Thank you so much for posting, maesy.

Those hybrids are very exciting. I predict good fruit quality.

There's an ichangensis x Satsuma cultivar here I'm working to get my hands on. Probably hardier than ichangensis x orange, I would assume.

A few of the F2 seeds from your ichangensis x sinesis may likely show a lot more hardiness than the original plant. Oranges are not really that hardy, so the first generation cross is not going to display the full potential.
(on the downside, seeds from orange are almost entirely nucellar, so I'm not sure what the zygotic seed ratio is of your hybrid. If the seedlings are all looking different, that's encouraging)

Yes I also expecting more or less good fruit quality.

But the ichangensis x sinensis is the pollen donor. The mother plant is the dunstan citrumelo.

Seedling close to the bottom could be a nucellar Dunstan, the rest are probably hybrids.
 I do not have an experience with this citrumelo ( my tree is almost 3m high but has not flowered yet).
Nucellar seedlings of 5star citrumelo have first  three  single leaves, than they are trifoliates. Its hybrids with unifoliate varieties are mostly bi and monofoliates at later stages.
Have you castrated the flowers?
What is amazing about ixs is an  absence of wide petioles , typical for other hybrids with ichangensis.
Your seedlings also have  petioles typical for oranges.
Best regards,
                       Ilya

Yes I also was missing the wide petioles, but  if I look very closely at the plant, there are a few leaves with slightly bigger petioles.
Becouse of that reason and becouse of the flavor of the leaves and the good tasting fruits I also was in doubt if it is true.
On the other hand I found this article about a somatic hybrid of ichang pepeda with valencia orange which suits very good to our i x s.

Lebming, great if it works, but I don't see the benefit except you need flowering PT The rootsystem will take a kongt time to take up with the one of a seedling I suppose.

Not really. The seedlings planted in December have a smaller root system than the cuttings taken in January. Why I don't know. Maybe because of hormones used. I believe there are few differences. PT from seed makes a long tap root, cuttings don't have that so they are more suitable for pots. Also I think an old PT as a rootstock makes the scion bloom faster like in the experiments where they use old PT as interstock. So it should be better for instance to induce flowering in seedlings grafted on it.

Ichangquat seedlings, much bigger now with many leaves


Ichang papeda cutting

was taken from a tree growing outside in a garden in downtown Portland, has been growing very well

It's always refreshing to see vigorously growing Citrus that hasn't had to face the ravages of winter. Will these plants be exposed to this coming winter's outdoor temperatures?

I'm not sure yet. I'd prefer to graft them on trifoliate, or a trifoliate hybrid, before putting planting them outside, and so far I don't really have any trifoliate hybrids big enough to graft onto, and I would probably want to grow the graft on to the rootstock inside to ensure it takes, which could take even more time before it goes outside.
It might survive on its own roots, if I just planted it outside right now, but from my experience with this last Winter, I am reluctant to take any chances.

I'm confident it would survive, I'm just concerned it might be killed back and be a third of its size, which would be a big setback. I'd like to try planting it out on trifoliate. However, they are rapidly outgrowing their containers, and it's difficult for me to have many large containers growing inside.

Tai-Tri seedlings (taiwanica x trifoliate)


US 852 (Changsha mandarin x trifoliate) seedlings


N1tri (ichangensis x trifoliate) seedling

It has grown and finally looks healthy now, like it can start growing with more vigor.

This one I suspect could be a tetraploid seedling of Ichangquat, due to the slightly larger thicker leaves and dark green color.

If that's the case, it may be very useful for breeding future seedless hybrids.
(Any cross a tetraploid has with a normal seeded diploid variety will end up with a triploid seedless variety offspring)

US 852 (Changsha mandarin x trifoliate) seedlings.  Which trifoliate did you use?

Perhaps you misunderstand. The seedlings came from US 852.
So that would be the F2 generation.

In some ways that makes things more interesting. Sometimes recessive traits can get expressed in the second generation that did not get expressed in the first hybrid generation, or certain undesirable dominant traits can be eliminated. There's the potential for the F2 generation to inherit the best of both traits from both original parents that weren't possible in the F1 generation.
