Citrus General Discussion / Re: Non-acidic orange
« on: January 15, 2021, 08:43:43 AM »
Vaniglia is slightly bitter and initially has some acid.
In Maghreb Meski orange landrace is more common. I have one seed grown plant from Tunis  that gives fruits without any acid even in September when they are still green and  small.
Acidless oranges are revolting to  people who expect a normal orange taste, but with the time I  found them rather attractive having a unique, banana like smell.

Thank you. Actually trifoliate leaf form is determined by several codominant genes.

Could you tell us what kind of hybrids you managed to produce with them, please.

Cold Hardy Citrus / Re: F2 citrange winter hardiness trial

Kumin, I wonder if you kept some nucellar seedlings in cold frame  as a control? What is their resistance?

5
Yes, they were frozen, but only for a few hours.

6
mikkel, before freezing the seedlings were acclimated at 12C and Led light 9 hours/day for two weeks. The plants were in plastic container and freezing was first gradual to 0C, equilibration for  3 hours at -3C to let substrat to freeze and than going to -9C with fluctuation on controller of + - 1C

7
My reference control are young seedlings of 5* citrumelo. They lose some leaves but no damage otherwise. The same procedure applied to 5*XTaitian cross gave only 4 survivors out of 150 hybrid seedlings.

8
Actually I have already done this cross. It produced more than 200 hybrid seedlings that in spring were exposed to artifical freezing at -9C for 2 hours. Two dozens survived, three had no damage at all.

Do we know what happened to this interesting hybrid?
I has not be able to find any further information on it.
In  leaf freeze resistance tests it was shown to have a similiar or even better hardiness than US119.

Ilya, the link no longer works.  Do you have this information elsewhere?

Cold Hardy Citrus / Re: Kabosu
« on: December 23, 2020, 04:16:51 AM »
Thank you very much for a detailed report. I was never aware of sweet taste of internal membranes of Kabosu. I also noticed that older leaves are yellow now. Is it a regular feature of this variety?

Cold Hardy Citrus / Re: Long term cold hardy citrus breeding project
« on: December 17, 2020, 04:07:56 AM »
If you select out of large hybrid populations, there are sufficient number of hardy plants. Absence of trifoliate taste can be also assured. But of course for sweetness, size of fruits etc., you need to wait for plant maturity. I have a dozen of plants that produce fruits, but have not yet attained my goal.

Cold Hardy Citrus / Re: Identify this fruit?
« on: December 16, 2020, 04:24:33 AM »
In order to get its seeds it is necessary to artificially pollinate with a lot of foreign pollen. The best is that of Meyer. The resulting seeds are nucellar  with many embryos.

Here is a second harvest of one of the  Morton seedlings from 2011 fruits described above


 




Most fruits are round without distortions, but this variety is a magnet for citrus bud mite giving occasionally very strange forms

Hello Lebmung,
What is a Bordeaux mixture ?
Bordeauxbrühe

Cold Hardy Citrus / Re: Poncirus fruit comparison
« on: December 07, 2020, 09:15:45 AM »
Robert, for already germinated seeds removal of this internal envelope is doing no harm, but I have seen some molding when it is inadvertently removed together  with testa.
Could be just a problem of scratching damage.

Cold Hardy Citrus / Re: Some rare variety hardy seedlings
« on: December 07, 2020, 04:57:34 AM »
Lebmung, are you sure that you have Ichang papeda or Ichang Lemon or something else.
I have been growing three different clones of papeda and they all have leaves smelling like lawn grass with a hint  of parsley, very different from lemon.

Socal, you are using data for the peel, not juice, these are two completely different stories.

Citrus General Discussion / Re: Pomelos
« on: December 04, 2020, 05:55:41 PM »
Tedburn, yes, Sarawak is considered as a synonym of Taitian.

Millet, I am growing some varieties in pots that are kept in cold frame during the two winter months, but later are moved to conservatory.  Taitian is in flowers at the beginning of March and fruits begin to be edible in November.

22
The bitter taste of grapefruit is not due to the presence of furanocoumarins. Pomelos contain approximately the same concentration  as classic grapefruits. For other varieties  the highest, almost 3 fold greater amount is in Combava, limes and sour oranges are also rich in them.

I think Taitian is the best pomelo variety available in Europe.
It is quite sweet and juicy in 9 months after flower. In isolation it is completely seedless.

Cold Hardy Citrus / Re: Ichang papeda fruiting season?
« on: November 23, 2020, 11:09:45 AM »
   I grafted a small branch of Ichang Papeda on a young Poncirus seedling last fall. It surprised me with its flowers at an early age. The rootstock is not even 1.5 years old.
It is quite normal that mature wood grafted on juvenile seedling flower early. Rootstock does not influence the degree of maturity of the bud.

Cold Hardy Citrus / Re: How to overwinter potted Poncirus
« on: November 22, 2020, 02:39:34 PM »
It will be difficult to keep greenhouse at around 0°C all over the winter. At temperatures higher  than 12C it starts vegetation and can be damaged by sudden temperature drop. 
Poncirus is hardy up to -24C; it should be completely resistant in your climate if you put your pot in ground close to greenhouse.
