To read the article is enough to understand.

It is a nucellar seedling then no P.  trifoliate parentage.

I sent you a PM.
Don't forget to tell me the exact place in the site arborescence.

I repaired the link in that page (viewtopic0469.php). You car read the whole story.
The Prague chimera is probably the greatest discovery we made for the north countries growers!

What happened since that time is on this forum: http://tropicalfruitforum.com/index.php?topic=23499.0

After more than three months of work at eight hours a day and 7d / 7 (and many nights too) here is finally the backup of the Citrus Growers Forum. It is far from being completed, but I am going to continue to work above. The function "Search" will be functional only when the site will be indexed, what can take several weeks.
Many of the images hosted on images hosts disappeared as on all forums. >:(
You can indicate me the errors by specifying the address of pages.

Send the news to all your citrus growers friends!

Very interesting. Could you look your other seedlings populations to see if Thomasville is an exception or the rule?

> You can also distinguish seedlings  by the appearance of leaves clockwise or counter clockwise
I too thought about that. I noticed that the sense of rotation is acquired for ever and follows the graft, but among seedlings you can find  clockwise and anticlockwise. So it looks more like  a congenital trait than a hereditary trait.
Indeed it would be fascinating to find a population made of uniquely one sense of rotation or a plant that have changed it's sense of rotation!

The leaves you are talking about are called primordial leaves. In citrus they mostly are opposite but some time alternate.
Just to use the right words.  ;)

Indeed you can use any of my pictures.
I look for yours but as they were on postimg.com, they are lost.
The only one I found is this one:

Let's say for Christmas.
This year I picked them the first days of the new year but many people would feel them overripe, very sweet with low acidity.

Ilya,
> does this mean that seedlings that you showed were from monoembryonic seeds with white cotyledons?
No, not at all. The seedlings I grow all come from one seed, the only one I had in many years. I Think the cotyledons were green but the main thing is that the seed looked like a "normal" citrus seed, like a lemon seed. The ones of this year are very different. They are big and puffy and we can see the green cotyledons through the testa. It makes bumps on the seeds making me think they are polyembryonic but I still didn't open one. They exactly look like yuko seeds that are very polyembryonic.
The 'work' of these days is to eat the fruits and collect the seeds. Later I shall take pictures.

Snek,
> Hybrid (Unshiu x P. ITSZ Prague“ is the greatest mystery among citruses for me.
It will remain like this as long as you shall consider Prague chimera like a(n) Hybrid.
When you will think of a chimera, everything will become clear and even evident.

> I've seen some of it in very old photos (50's or 60's). And it looked very convincing. E.g. orange, sometimes with trifoliate leaves.
If you know an equivalent chimera with orange please immediately take cuttings ( and send me some ;-) ).

> When cutting the screws, the second genome remained on the original plant. Is it even possible? If so, could it happen to the hybrid (Unshiu X P.T.) ITSZ Praha? If it's a chimera.
I am not sure to understand this sentence but if you mean "is it possible to obtain a pure mandarine fruit from a(n) hybrid of poncirus", the answer is absolutely 'NO' for an hybrid and absolutely 'YES' for a chimera!

It is the same for a pure trifoliate branch, the answer is absolutely 'NO' for an hybrid and absolutely 'YES' for a chimera!

It is the same for monofoliate polyembryonic seedlings and for everything we can see on the prague. It is always NO for a hybrid and always YES for a chimera.

Last news. In the crop of this year most of the fruits are flatten at the distal end, like satsumas. The fruits of previous years were near-spherical. I find from 0 to 3 seeds per fruit. The seeds are also different. They are big and we can see trough the thin testa the green cotyledons. They look poly embryonic.
The pulpe is still the same: a pure mandarine.

> From what I know precocious flowering gene in poncirus is recessive
> I agree with you about those recessive genes, Walt.
I received them as seeds and all the seedling flowered  one and half year later.
But it doesn't prove it is not recessive because all the seeds could be nucellare.

It is MIC. Not so rare...  :)

Well, I don't think it is very accurate but it doesn't matter much.

Any way it is not a question of copyrights but of fairplay and courtoisy to ask him before we release the back up.

Millet, I think the "change.org" proposal is just a teasing joke.
