Citrus General Discussion / Re: Nordman Seedless Nagami Kumquat
« on: March 20, 2023, 09:49:25 AM »
one part is seedless the other forms nucellar seeds, not a good prospect. But trial and error will show if it works out

Cold Hardy Citrus / Re: The eremo- hybrids, which ones are worth it?
« on: February 16, 2023, 02:39:23 PM »
You are right, of course. In F1, the genes are always distributed 50:50 (in genotype). What I actually meant was that the phenotypic trait expression does not necessarily have to be 50:50.
The phenotypic expression of the poncirus genes depends very much on the dominance/recessive properties of the individual genes.
(There are also other factors)

Somewhat theoretically speaking :) A hybrid of Poncirus and a Citrus does not necessarily have 50% Poncirus gene. an F2 like Eremoorgange or Eremocitrange not necessarily 25%.

With each new pollination there is a recombination of genes.

Which genes are expressed phenotypically varies from seedling to seedling. Therefore, hybrids vary greatly in their characteristics from seedling to seedling. Some have poncius traits, others less or not at all.

Percentages are purely hypothetical.

Cold Hardy Citrus / Re: Interesting kumquat and other hybrids in Argentina

this can be easily recognised by the colour of the new shoots. anthocyanin-free varieties are green, anthocyanin-containing ones reddish to red. anthocyanin is probably linked to the acidity of the fruit. Varieties with green shoots, i.e. anthocyanin-free varieties, tend to be low in acid.

Cold Hardy Citrus / Re: F2 citrange winter hardiness trial

Probably only phenotypically a poncirus alike, but not in genotype. i was thinking the same.  If it inherits its hardiness, these could be promising hybrids.

I also found some hardier C35 seedlings even some monofoliates. But not as hardy as yours.

Interesting. do you think picture 3 and 4 could be tetraploids?

Yuanjiang Papeda is quite different in fruits and leaves.
Yuanjiang Papeda is classified as Ichang Papeda

On the other hand weak roots are sometimes correlated with less thorns or precocious flowering. Just in case this is of interest.

Are these the mother plants?
So f.e. the first line is Tarocco rosso x Nagami?

I can not say. The seeds were given to me.

I have had FD seedling batches with almost 100% normal growth habit.

Cold Hardy Citrus / Re: Precocity and tree caliper
« on: January 23, 2023, 06:01:08 PM »
I think this phenomenon fits very well with the node count theory. Your trees have grown very fast and have reached the crucial height, that's why they are flowering .
From the reverse I can report that Poncirus hybrids here in northern Germany lack summer warmth and grow very slowly, mature poorly and often freeze back and stay immature for a long time.
Your trees have a long growing season a warm climate in the greenhouse and probably a good supply of nutrients. That speeds things up.
Ichangensis hybrids often start flowering on the lower branches first, interestingly ichangensis hybrids flower much faster and at lower heights than poncirush hybrids here even outside. In the greenhouse I had the first fruits in the 3rd summer at just about 1m height and that on the lower branches.
I think fast growth is very important, the genetic predispositions also play an important role and with fast growth these are fulfilled faster.

Are there sources for Novak and Shambala in Europe?

 Do you have any news on this topic?
Finally a received a Rose Anne. It started to flower around Christmas but lost it due to cold weather. I am eager to see if it will flower a second time in spring as promised.

Are there any commercial sources for deflexa?

11 months from germination and it flowers? that is faster than I had hoped.

Do you mean Sunquat?

Cold Hardy Citrus / Re: Citrumelo
« on: January 16, 2023, 03:39:10 AM »
There are several varieties of citrumelo. They differ in taste, hardiness and so on. By and large, the rootstock is not very important for the taste. On closer look, there are some differences, but with citrumelos it's mostly a matter of whether they're edible at all....and this also depends on individual preferencies

Isn`t it a Nagami x Meiwa hybrid?

Cold Hardy Citrus / Re: looking for most cold hardy poncirus trifoliata
« on: January 15, 2023, 02:36:47 PM »
P.polyandra is way less hardy than trifoliata. I would say -6C is already a thread. I lost larger branches at -6C.
It doesn't die at single-digit subzero temperatures, but it doesn't thrive either. I don't think it will survive -10C.
