Cold Hardy Citrus / Re: hybrids with precocious Poncirus
« on: Today at 08:58:43 AM »
I have seven precocious Poncirus seedlings here and if they really do flower after only a few years I will try to cross them with other citrus, too. If the early flowering could be transferred to the offspring, this would save us many years.

No one really knows what happens after the F1, so hybrids with Yuzu or other parents may indeed result in hardier offspring somehow, somewhere down the road.. but for now, I regard C. ichangensis or N1Tri as the most promising parents other than Poncirus because neither Yuzu nor Ichang lemon come even close in terms of coldhardiness (there are, admittedly, wimps among C. ichangensis as well but I have not seen any Yuzu survive anything lower than -15C).

Interesting results, thanks for sharing.

This topic is turning out to be so great, thank you all for your contributions.
Sylvain, your plant has a nice, tall trunk. Did it form that all by itself or did you prune it that way? I am asking because you say it will grow upwards over time anyway but at the moment I doubt a bit that mine would form such a nice trunk..

Sylvain, would you have a picture of your plant and fruit?

Well, Ilya said that the homogenous dna makes it rather unlikely to be a chimera but I am no expert.

Thank you so much for the information, Ilya. My plant is a strong grower but I would still like to graft it onto a taller poncirus because I like tree forms better. I will let it grow until it flowers and try to graft it then. I need more time anyway because my poncirus rootstocks are still very small since I have to grown them from seed.

I'd like to share a picture of my Citsuma Prague which is the most bizarre citrus I have.
It has grown pretty well but it seems it wants to grow in all directions but upwards. If I let it grow it would be much wider than tall.
I know Ilya has one, too. I'd love to see some pictures.

Oh, it will. It has started to grow new leaves even where there are no leaves and where it looks half-dead. I reckon about 1/4 to 1/3 of the branches are really dead.

Ilya, my fruit wasn't quite ripe by the end of the year but I think the first fruit isn't representative. Also, the spot where it is planted could be a bit sunnier but I am quite short of space actually. Apparently, they ripen in December in Ticino.

I am sure you know this post:

The fruit weighed 108g and measured about 5-6cm. So, not very large but I think as the tree grows larger so might the fruit.

And here a picture from March 2017

A bit late but my Citrus ichangensis x sinensis is quite promising. It took -8C several times with no damage last winter (15/16). This winter freezes lasted much longer and the mean temperature in January was only -3C with lows of around -10 C. The little tree (about 50-60cm) lost 3/4 of its leaves and some younger twigs. I am very surprised it is still alive. It seems that not the absolute low but the very long freezes were what got it. I think its hardiness could be similar to yuzu, perhaps a bit less.

I have only had one fruit which wasn't the full size but the taste was quite good. No off flavours, juicy and sweet just like an orange. It had no seeds but I know they can have a few.

The only drawback would perhaps be availability for non-europeans. Still, I wanted to share my experiences.

Cold Hardy Citrus / Re: Ichangquat other than 6-7-2

Yes they are but so is the Ichangquat. Unless they took the budwood from a juvenile plant.. I've just bought them all toghether.

Thanks a lot, I knew that many citrus are thorny when young. But the other plants which I ordered (Juanita, Citrumelo Nr. 82 and Citrandarin Nr. 174) are of the same age and almost thornless. So, my real question is actually whether the Ichangquat will be full of thorns when adult, too.

Ilya (or anybode else) does your ichangquat have any spines/thorns? My ichangquat has lots of them, the largest measuring 5cm (almost 2 inches). Quite a dangerous thing if this trait persists into adulthood.

Sorry to dig this post up but could anyone tell me when Juanitas ripen? Any chance they ripen before the end of the year in cooler climates?

I know that one, they do not ship to Switzerland, unfortunately.

I bought it from Eisenhut, Ilya, I don't have many other options:-). I believe it has not flowered there.

I have just bought an Ichangquat and I was told it is a sister hybrid of the 6-7-2 and that it came from the US but I couldn't get any more information (ie. on hardiness or taste). So, I'd appreciate any additional information there might be.

Thanks for the warm welcome. It would be a pity if your customs didn't allow to send citrus seeds (since I understand they can't carry viruses, can they?). We shall see.. :)
We do indeed have some interesting citrus varieties here but so do you. For example I have never seen a Clemyuz 2-2 for sale here (let alone a dekopon). Also, the Japanese have some good stuff which nobody seems to be able to get their hands on like the seedless Yuzus or the real Yuko..

Hi everyone
I am new to this forum. I have an ichangensis IVIA and Ilya is right when he says the fruit is quite edible (that is compared to other ichangensis cultivars or Poncirus). My plant is still small and the fruit might become bigger as the tree grows larger. There was not much pulp in the fruits I have harvested so far but there is , in contrast to other ichangensis cultivars. The juice is usable just like lemon juice. Another plus is the fact that they ripen even in our cool summers.
I know reports from Germany of trees surviving down to -18C but I don't know about the IVIA. I haven't tested mine yet since I want to let it grow a bit larger first.

If in the future it should contain more seeds, I will be happy to share them.
