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.
