Citrus General Discussion / Re: Fukushu vs. Meiwa
« on: June 20, 2022, 10:48:38 AM »
I don`t know Fukushu but I ate Meiwa once. For my taste it is a really good one. You can eat it as whole. It much better than Nagami no need to say.

You're right, I didn't read about the hybrid origin. But still the seedlings look very similar to my australasica seedlings.... If that means something I don't know... it's just an observation

If I add my 5 cents.... I also do not think it is glauca. glauca should have different leaves.
Yours look similar to my Blood Lime

I was talking to Bernhard Voss. He said the one with thorns is the diploid one. the tetraploid one has no thorns. At least one of these should be the diploid one.

What made you think it is diploid? I was thinking about it too, but Lenzi told me he has no clue what is the caes with these both...
I found similiar types (which might be the same, who knows? ) via a friend in a small nursery. I keep collecting hindsiis :)

I like Meiwa. I wonder if the skin on a Meiwa/poncirus hybrid will taste nice. Or it might taste like poncirus. Wont know til ya pop it in your mouth and chew it up!

Meiwa is the most valuable kumquat in my eyes. It is very tasty, much better than the varieties from the supermarket.
But Meiwa is supposed to be strongly nucellar. Since Poncirus is often too nucellar, it would be quite a challenge to produce hybrids. But it should work with a large number of seedlings....

The big disadvantage of hindsii is that probably only the tetraploid version is available. At least I have not seen the diploid version yet. But this would inevitably lead to triploid offspring. Only in rare cases can triploids produce seed. I believe procimquat is such a case (but I'm not sure if my memory is correct)
Also other kumquat types are supposed to be early flowering, maybe other types are suitable?
@Marcin I have different hindsii from different sources. If you are interested I will send you some rice.

@Till backcrossing with kumquat would also have to include selection against such strong dormancy. But in Marcin's case, he is in a more continental climate with warmer summers than our climate. That might be less of a problem for him?
But the disadvantage is indeed that large quantities of seedlings are needed to select for these traits. And that, as always, is a problem.
Backcrossing with Poncirus is disadvantageous in my eyes because Poncirus is already sufficiently winter hardy, but the backcrosses are very unlikely to have improved fruit (it is still not impossible of course) a backcross with Kumquat would first improve fruit quality. With simultaneous strong selection for winter hardiness.
In theority, backcrossing the hardy BC1 hybrids would then have to be done again with kumquat, until winter hardiness and other traits are transferred.
I think this is at least one way, but not the only one.... for time reasons alone, I would go both ways. And it is theory, there may well be other ways.

I think the advantage of backcrossing to kumquat is to improve the fruit while reinforcing the good winter dormancy....
For winter hardiness, of course, it would need a strong selection from many seedlings. Most of them will not be hardy enough... So far the theory :)
The practical side is that they must first mature and form fruit.
I could imagine that a foil greenhouse could already work well with you, the summers with you are warmer than here and a foil greenhouse could push them properly. Just as @kumin has done. He has already had some flowering trees after 3 years that way.
I also dream of a garden in the south where I can raise the seedlings until they bloom.... or a cooperation with someone in the south..

I have got new pictures

longispina has no petioles. excelsa does not fit at first glance either.

there is not much information about it.
I found it in a catalog of a local nursery. This nursery has built up its stock many years ago. It still has some of the varieties from the early days, when the citrus hybrids experienced their first rise in popularity. So, out of curiosity, I ordered it. I found that there are some mentions in France and even in some collections, but no reference to their origin. I wonder what kind of hybrid it could be. I have been told that the fruit looks like a limette, but no word on fruit characteristics. Probably nothing to speculate on.... but who knows...

Does anyone know the Karasu Papeda? There is not much to find about it.

next step: backcross to Kumquat :)

Ilya, is the precocious Poncirus also flowering as early as on its own roots when grafted on standard Pt? If I remember right @Till told me that grafted precocious Pt isn`t flowering for him. What is your experience with this?
Small poncirus in general are slow growing outdoors for me. Only in the greenhouse they grow sufficiently. But even my grafted precocious Pt does not bloom in the greenhouse.

they send to Denmark. If you find someone from Copenhagen who can receive it for you... Is SLU still collaborating with Copenhagen?

Cold Hardy Citrus / Re: new thoughts on breeding hardier citrus
« on: May 21, 2022, 02:45:38 AM »
There is a discussion about that on CitrusGrowersForum

Have you looked for snails? I have several types of citrus close to each other in my garden, some are attacked by snails, others are not. I just discovered it by chance, because they appear only in the evening. The slugs specifically attack the new growth, so it looks like the plant is still in dormancy.

Is it similiar to this one?
It is Augusta Citrangequat at McClendons Yard

Cold Hardy Citrus / Re: Monoembryonic Hardy Orange?
« on: April 23, 2022, 06:31:26 PM »
I meant it's easy to keep the bitter taste :)
You can dry and store the pollen.
Most of my poncirus seedings are actually monoembryonic, (from different sources) , I don't know why, but the polyembryonic ones have been in the minority. among some I have also found direct F1 hybrids with poncirus as mother, trifoliate but with enlarged midleaf.
The more you sow the greater chance you have to find hybrid seedlings.

I want to keep the bitter flavor, at least in my baseline plants.  What I need are zygotic specimens.

this should be easy to achieve :)

Once I got seeds of this monoembryonic poncirus. But I lost them.
Maybe the UCR still sends seeds?

I must correct myself. the petioles on my Ichang Papedas are not only widest in the middle but also at the top. but the middle is already as wide as the top....
This can be seen on the picture better than in my description

For me, Ichang and its hybrids grow better than Poncirus and its hybrids.
The size of the petioles change over time, but the shape remains pretty much the same. On your plant, the top part is the widest. On my Ichangensis, the middle part is the widest. Hybrids tend to have a shape like yours. At least on my plants.

You really seem to have the right conditions for Poncirushybrids. Congratulations! I'm very excited to see how it goes.

« on: April 08, 2022, 04:20:26 PM »
My FD and Poncirus had such damage after a warm period in early spring. The freezing temperatures caught them then when they had already awakened from dormancy.
I also think that is the reason, as you have already written.
