No I didn' t have seedless ones.
Seems that without cross pollination they shall be seedless.

2
After setting and keeping 2 fruitlets from 2 flowers,
Thomasville remembers her Kumquat ancestry and
pushes a lot flowers after some hot days  8)

Too bad, could have given also a promissing cross concerning fruit quality
and more hardiness with early fruits.

4
Thank you Tamasz. Though I have not tested frost hardiness, due to
my experiences with the parents in ground since a few years.
And with three plants even one should have herited frosthardiness  8).

From the crossings Yuzmelo x Bloomsweet  left side and Chandler x Bloomsweet right side,
the Yuzmelo x Bloomsweet with Terminalflower set small fruitlet.
Before dropping the fruitlet I decided to taste it against a
Oroblanco Grapefruit fruitlet.
The positive surprise was that the fruitlet of Yuzmelo x Bloomsweet was
with nearly no bitterness, while Oroblanco was still very bitter.
So taste of this cross seems promising, so only frosthardiness
is still to test.


6
Finally after 5 years in ground my Thomasville brings first flowers  8).
Never damaged in Winters but with late sun she grew slowly




Also very nice, that slava micurina after 3 year in ground
had a few flowers


Bloomsweet after 3 years in ground also has some flowers,
very curious if fruits will be hold and how
they will mature in my climate.
My potted Bloomsweetfruits are eatable
November/ December.

I think every new crossing is interesting, the only problem with kumquat heritage could be the
late ripening time in zone7 and 8 with springfreezes which damage the fruit.

Very interesting the story of Dr.Frey and his selections.
Especially because I'm a fan of Sanford Curafora and since 5 years in ground it
makes me a lot of pleasure with growth, overbording flowers and better fruits
than many hardy citrus hybrids.
Thanks Usirius for these interesting excerpt of the book.

Cold Hardy Citrus / Re: Bifoliate Star Ruby seedling
« on: May 27, 2025, 10:38:28 AM »
Do you know where tve fruit came from, country ?
I also can hardly imagine that poncirus or Citrumelos
flower in professional fruit orchards  ;D.
But time will tell, if your seedlings keep this
trait it would have been a crossing
with trifoliate  ;).

Thanks Tamasz, the plant is from December 2023.
Yes for 1,5 years they are not too big, but in 2024 they didn't grow very well
and some died. So 3 left and now in 2025 they grow not fast but look good
 8).

11
One of my 3 resting Yuzmelo x Bloomsweet seedlings  shows a nice
terminalflower, also with nice decent smell.

Looks quite interesting with first valentine and then
trifoliat leaves.
Will you make an early freeze test ?
Leave taste also would be interesting.
Good success  ;)

13
I wasn' t aware of that, thanks Mikkel  :D

14
Also Hirado buntan x Keraji could be a good option

15
Today I started my crossings.
Had Pollen Yuzu N30 from Skandiberg (thanks again) and a nice
Flower of 5* Citrumelo.
Unfortunately after 90% of work getting pistil free one bad movement
of the knife broke the pistil :(.
O.K. lets wait for the next flowers  8).
See pictures.

Cold Hardy Citrus / Re: Dimicelli - What is it?
« on: April 30, 2025, 04:07:16 PM »
I also doubt 50% Trifoliate due to leaf shape.
Mine currently forms out first flower buds, I' m really curious
to fruit taste. From first clemyuz 22 fruits I was not 100% convinced
of fruit taste, had a slight aftertaste.
Hope Dimicelli is better.

17
Hello Muberry0126 and a_Vivaldi,
I can confirm you, that Keraji has a realy very good
manarin/lemonade taste and is
eatible from end of November also in my colder
climate. Only small disadvantage is the
medium seediness but for crossing it s no disadvantage.

18
Thanks Rei, Florian and Skandiberg for your suggestions,
I added them on my list  :D.
Very challenging due to a lot of opportunities,
but also very happy to have these opportunities.

19
Help needed  ;),
Below are my citrus with flowers and I would
ask you what would be your suggestions
for crossing, with the goal of good tasting
and as much as possible frosthardy under
respect of zygosity. Chandler x Bloomsweet
and Yuzmelo x Bloomsweet I made
already the last years.
I'm curious to your suggestions  8)

Citrus General Discussion / Re: Cold Tolerance after 2025 Freeze
« on: April 24, 2025, 02:26:21 AM »
For my experience
1. Rootstock is very important for cold hardiness
    (Poncirus is best)
2. Cold hardiness of grafted variety
3. Individual health status of rootstock and graft
.....
- Carizzo is not very cold hardy
- I guess the sometimes reported cold hardiness of
   Juanita is not existing. My Satsuma Collot on
    Poncirus froze down 5cm over grafting point
     at -9 °C but resprouted.


21
Very interesting description Lauta_hibrid.
I don't have finger limes, but I heard from eating out of hand
they are not the best - what was the goal to cross them with pomelo ?
I would rather cross to get more tasty fruits or more
Cold hardyness or good combination of these two
Characteristics.

Cold Hardy Citrus / Re: TaiTri
« on: April 20, 2025, 01:22:16 AM »
Not sure if Taitri is such a big gold nugget in citrus world   ;).
https://hardycitrus.blogspot.com/2014/02/taitri.html?m=1

23
Sometimes its strange how some cultivars make it and others don't.
I planted seven  2,5 yr old seedlings Citrumelo N82 last early summer at the same place
within a m2 in ground and left them unprotected this winter, all
about the same size.
3 showed nearly no damage, 3 looks a bit stressed and one
 died with bark crack.
So I think a selection with citrus cultivars make sense and I assume
same cultivars sold in different locations may show different
Cold hardiness or fruit taste due to zygosity.
Picture with the 6 survivors, died one already removed.


24
Today graftet my first own crosses Chandler x Bloomsweet wich took -8 °C as 1 year old seedlings.
But the 3 survivors needed 2024 to recover and now seem to be again in
pretty good shape and thrive.
Two of the 3 seedlings had more twigs, so
it was possible to take a smal scion of them
for grafting.
Now looking forward for further good and faster
groth on Poncirus and Citrumelo 5* rootstocks.

Cold Hardy Citrus / Re: Winter frost damages
« on: March 25, 2025, 04:07:19 AM »
Until end of february ( with coldest temps down to -10 ° C, from march to now,
after removing protection fleece some leave damage at Dimicelli by nightfrosts and early morning sun.
But overall a good result after winter  8).
