N1triVoss
« on: October 18, 2018, 02:41:56 PM »
A very promising cold  hardy hybrid  produced by B.Voss in Hamburg.
It is believed to have C.ichangensis  and Poncirus as parents. Leaves are mostly monofoliate and that is why I think that  the story is more complex, could be citrumeloxichangesnsis. 
My plant is now more than 2 m high, planted in 2012, never protected, never damaged.
Dozens of rather large pear-sharpen fruits.



Skin is pleasantly lemon-like, although not strongly scented, albedo is moderately bitter, no poncirus taste or odor.
Around 20 large, ichangensis-like seeds.



Moderately juicy, less bitter than grapefruit, rather acid, but less than lemon.
Some fruity aftertaste is faintly present, but is is very different from poncirus.
Amazingly, at this stage the juice already contains  a lot of sugar: 11.5° of Brix, approximately the same as commercial clementines.
Best regards,
                       Ilya

Sounds wonderful. More pulp to seed ratio than poncyrus means potentially more useful. I have some ichangensis seedlings with some trifoliate leaves ; I hope they grow to make nice fruit like yours.

Beware, It is not very hardy despite its parents.

I have a small plant that only just flowered for the first time.
Various accounts concerning hardiness differ greatly, I've read between -9 and -18C...

I can confirm that N1tri has good frost hardiness.
Last year I planted it inground to see what happens. For the winter covered it with white agrotextile. Winter proved hard, with a minimum of -21 C.


After the winter N1tri was severely damaged but some wood survived. I dug it out and planted again to a pot.


It has recovered fast and is in good condition now. Bark crack is still visible, but healing.

The photos show well the problem. It is not the green parts like in other citrus, it is the bark of old branches that split.
And it depends very much on the sap state. Some years it can look very hardy and some years it is very week.
One of my N1tri is much bigger than yours and this year it lost half of its branches by cork splitting.
This winter was very mild but we had -8°C (17°F) at the end of february. It nearly killed the tall N1tri but did nothing to the small ones that still have green branches.

This is why some people say it is hardy and some say it is not.

Yes, cracking of the bark was the main problem.
I wonder how does N1tri compare to Ichang papeda in frost hardiness. I have a small grafted IVIA ichangensis, maybe I'll test it inground when it gets older.

Sylvain,
It could be something connected with late summer growth.
As a rule I remove all new growth appearing after the middle of August. As you know I am hundreds kilometers North to you , this winter had -9.6C for several nights and 10 days without soil defreze. Some damage to Yuzus, but not even leaves loss on N1tri.
Best regards,
                       Ilya

My potted N1Tri has flowered for the first time this year and I thought all the flowers had dropped but today, I discovered this tiny fruit.

Perhaps you could wrap the older thicker branches in insulation. Plastic bubble wrap.

Florian, Ilya11

today I found this thread and I got a brainstorm.

From the description of the plant, pictures of the leaves and description and pictures of the fruits I have compared with my portfolio....I have a plant that is actually not N1triVoss, the rest of your description would exactly fit. It is much older  than N1triVoss began to existing. So I have an assumption....

I add some flower Pictures of my plant, which shows very Special flowers.

Can you please compare them to the flowers of your plants N1triVoss,  and give a Feedback? Maybe you can add Pictures of your flowering plant.

Usirius, the flowers on your plant look very similar to these of citrangequat 4 saisons.

For whatever it's worth, I have a little N1tri seedling.
It doesn't look the best and hasn't been growing well or growing very fast.

Usirius,
It certainly not a N1tri that I have, both flowers and leaves are very different, my plant is about to start  to flower  now:

@All, thanks for your comments.

What I think - according to the description of the fruits and leafes....I have bought this plant called "Citrangequat" for about 25 years ago - from nthe ursery  PAICHI GARDEN in Spain. This Show es described pear shaped fruits - with similar taste and the leafes are also as described. It show nearly no thorns, and Poncirus is not to seen in the Habitus. By luck it Show one bifoliate leaf in one or two years.

In the the Moment I have no fruit available for taking a picture.

Recently I received seeds of N1tri from Ilya. Here are some seedlings
N1tri F2 by michaelbasso, on Flickr
N1tri F2 c by michaelbasso, on FlickrN1tri F2 b by michaelbasso, on Flickr

leaves are different from palnt to plant, mostly monofoliate but some are more or less trifoliate. Some are bi or trilobed like e.g. Passiflora leaves.

Do you know the pollen source or were they open pollinated?

The seeds came from Ilya. I guess it was open pollination.

Those were the seeds from open pollinated N1tri. Nearby I have 5star, Morton and Ichangquat. Castrated and isolated flowers of N1tri gave seedless fruits.

Anyone have a source for plants or seeds for this in the states? I have been looking to no avail and would love to add this to my collection.

5 month old seedling N1 Tri Voss has first flower  :). I had got N1 Tri Voss fruits from Petr Broza, he is growing N1 Tri Voss in big greenhouse with many other citrus varieties, so this seedling may be also hybrid from open pollination...

I found at least 3 very early flowering seedlings of N1tri from open pollination. None of them have ever bloomed again.

This grapefruit-like early flowering on the top of stem growth occurs often in N1tri seedlings.
It is one of the reasons why I believe  that this variety is a a hybrid of ichangensis  with some sort of citrumelo.
These flowers are giving very rarely fruits because the whole plant at this  stage  is rather weak.
But if you cut them near the ground, there is a chance that new emerging  growths  will flower on the tops next spring.
