I have no suggestion but I can tell I have some candidates likes this since 2 years. Still alive but no growth. I take part on this question.

@Heinrich where did you buy the plants? Are they from Hrn Meeder?

Thanks Citradia! By what scale were the fruits evaluated, edibility?

on Jauce you can find japanese grower selling their fruits. They send worldwide. If you are allowed to import Citrus it might be a source for seeds. But for EU Citizen it won`t work...

They are selling seeds of a seedless Yuzu?  I am just asking :)

What kind of disease could this be? They wilt from top to bottom but roots mostly survive. After some time some sprout again from roots.

Vaniglia orange x Ichang Papeda gave me monoembryonic seedlings with clearly intermediate leaves. It might be also a orange with zygotic seeds.

Citrus General Discussion / Re: The History Of Citrus Fruit
« on: August 14, 2017, 03:27:09 PM »
I am convinced that it actually depicts a pine-cone and that the artist added some leaves - just 'some leaves in general' in the back to make it symmetrical with the leaves that are depicted behind the bowl on the left side.

That is what I thought. If you look precisely you see the leaves are not on the top of the cone instead a little bit beside. wouldn`t make sense if you want to depict a pineapple.

The question is how can a pineapple be still fresh when brought from south america to the mediterranean sea when you consider ships of that time. It would take a very long time. And still if it would be possible how often must ships sail from Rome to south america and carry pineapples with them that it is so famous to be depicted on a mosaic.  There was no TV, Radio or newspaper means people must have seen it by themself or very close to it at the most 3rd hand.
It must have been be a usual  trade route than.
If it would be common knowledge that south america exist there should be literature or other artefacts.
Another point is were pineapples at this time cultivated in south america and already of that size they are today?

I think it is very unlikely and it is some misinterpretation even though the pictures look very like pineapples.
I don`t say it is impossible that Romans could have been in South America but I think it is not likely pineapples were traded at that time.

To heat up the discussion have you heard about the Chachapoyas in the Andes? They are supposed to be descendents from Celts from Spain. That was just in the beginning of  the Roman Empire.

@SoCal2warm
amazing how you doubt everything others found out in more elaborated studies than just looking on pictures. I am not saying all is true what is consensus today, but where do you get all you knowledge from? Do you have sources did you research or is it just as you wrote kind of " I think..."
Please let us know.

Cold Hardy Citrus / Phelps Citrange
« on: July 03, 2017, 02:59:58 PM »
Anyone have seen a Phelps Citrange by himself? It is sometimes mentioned together with Sanford Citrange. Phelps Citrange produces mostly zygotic seeds as Sanford. I could not find any first hand information about it.
Thank you!

I miss some links to scientific studies mentioned in the post. I doubt Yuzu a cultivated species could be ancestral to a wild species like Ichang Papeda.

This is a true Ichang papeda and where it grows

around winter 2015/16 I applied Paclobutrazol on many of my plants. Also on some seedlings.
Now I found a 2 year old seedling of a Ichang papeda with a small flower on top. It is only one seedling among many others and I am not sure if it is because of the treatment. Future will show if this plant is already mature or not. Maybe it only happens once like with some grapefruits.
Here is a picture sorry for the bad quality

here you can see how Paclo works. Seedlings grow very bushy.

Yes that is what I meant. Didn`t know that monoembryotic are often nucellar too.

But also Thomasville, a young hybrid compared to them is almost stable when sown. I am aware of nucellar seedlings but also the few monoembryotic and probably zygotic ones differ only slightly from it. haven`t seen any segregation towards trifoliate leaves in seedlings so far.

Any thoughts?
I tried a lot to produce hybrids with Thomasville as a seed parent, but failed up to now.
Never seen any  zygotic seedlings from it.
But when I used  its pollen on 5* citrumelo flowers it gave two fruits  and dozen zygotic seedlings.
Thanks. A lot of my seedlings are monozygotic but probably not zygotic then. I`ll keep an eye on them.

Citrus General Discussion / Re: whole new subcategories of citrus

I always wondered how all these different Citrus types could evolve just by crossing different species. On the top these are still stable types an orange is an orange you won`t get any segregation in the F2 back to the parents.
If Yuzu is a simple cross between Ichang Papeda and a mandarin how could it stay stable for such a long time without splitting in uncountable different varieties.
Okay it is a long time ago that these types evolved so maybe there was selection and these type got stable over the time by that. But also Thomasville, a young hybrid compared to them is almost stable when sown. I am aware of nucellar seedlings but also the few monoembryotic and probably zygotic ones differ only slightly from it. haven`t seen any segregation towards trifoliate leaves in seedlings so far.
E.g. if you cross different wild apple species you won`t get a new species. At least F2 would segregate back to the parents. The only other example for a stable new species / variety is Aesculus carnea a cross between the european Aesculus and an american one. Seedlings will give A. carnea again.
Any thoughts?

Is there a web source where can I read more about these varieties? Thank you!
