Here is a picture of original tree posted by eyeckr in old citrus forum.

Tropical Fruit Buy, Sell & Trade / Re: incan peanut seeds for sale/trade
« on: December 13, 2018, 12:05:24 PM »
Incan peanuts doing well in 100 litre pot, together with one maracuja seedling.
(btw: when I put this sentence to google translator to check spelling, translator suggested to change word maracuja to marijuana  :o / strange world we live in)

When I moved pot indoor for winter, plants started decline, only one survived. Now, after four years it blooms.

Citrus Buy, Sell, & Trade / Re: Wanted: Citrus reticulata 'Jiouyuezao'
« on: December 13, 2018, 10:41:21 AM »
Jiouyuezao (September Early)九月早 is a chance seedling of the Citrus reticulata Bendizao obtained in 1960.
Trees are hardy, surviving temperatures as low as -13.4 degrees C in 1991.Fruits mature in late September-early October, weigh 48.6 g on averrage.
(Liu, Z.Z.; Yu, L.M., 1993: Jiouyuezao - a hardy mandarin germplasm.)

about Bendizao I wrote here:

Typical behaviour of big transnational companies, everything for profit. Their only god is gold calf.
The same situation is in meat industry. Chickens in mass production farms are  feeded with antibiotics practically on daily base. Etc.

New cultivars:
Aliza  Orah c. reticulata x Chandler citrus maxima
Cookie Frua c. reticulata x “Siamese Sweet citrus maxima

Very funny: they should be spelled differently:
Aliza  Chandler citrus maxima x Orah c. reticulata
Cookie  Siamese Sweet citrus maxima x Frua c. reticulata
(seed parent precedes a pollen one)
Could be a problem of the back translation from Hebrew :)

My mistake, I rewrote it directly from the book thinking that first is always mother, but for some reason, they put father first.

So correct is:
Aliza  Chandler citrus maxima x Orah c. reticulata
Cookie  Siamese Sweet citrus maxima x Frua c. reticulata

It also gives a sense, when you want a big fruit as follower.

Aliza  Chandler citrus maxima x Orah c. reticulata was named to honor breeder Aliza Vardi.

Part list of drugs that interact with Furanocoumarins.:

Dasatinib (leukaemia)
Erlotinib (lung cancer and pancreatic cancer)

Pazopanib (kidney cancer)
Sunitinib (kidney/gastrointestinal cancer)
Vandetanib (thyroid cancer)
Venurafenib (skin cancer)
Erythromycin (antibiotic)
Halofantrine (antimalaria)
Maraviroc (antiHIV)
Primaquine (antimalaria)
Quinine (antimalaria)
Rilpivirine (antiHIV)
Amiodarone (heart rhythm disorders)
Apixaban (anticlotting)
L. Fidel et al.
Dronedarone (heart rhythm disorders)
Eplerenone (heart failure)
Felodipine (high blood pressure/angina)
Nifedipine (high blood pressure/angina)
Quinidine (heart rhythm disorders)
Rivaroxaban (blood anticlotting)
Ticagrelor (blood anticlotting after heart attack)
Oral alfentanil (painkiller)

This is the reason why Israely breeders are developing cultivars with the taste similar to grapefruit, but with low level of Furanocoumarin.
New cultivars:
Aliza Orah c. reticulata x Chandler citrus maxima
Cookie Frua c. reticulata x “Siamese Sweet citrus maxima

I can recommend Hana Fuyu, heavy bearer, sweet, no need pollinator.

Temperate Fruit Discussion / Re: Best Persimmon tree to buy
« on: December 08, 2018, 08:40:59 AM »
Here in Europe, specialized nurseries sell tens of cultivars, common nurseries sell few basic japanese persimons (d. kaki) like:

Hana Fuyu
Giant Fuyu
Rojo Brillante

sometimes Jiro, or Cioccolatino.

I have Hana Fuyu and Tipo in greenhouse, this year I bought Cioccolatino, which is very good pollinator. Here in zone 6 it is lottery to grow d. kaki outdoor, This is why those, who want to grow kaki outdoor are focusing on crosses of japan persimmon and american persimmon, which are more frost hardy like

Nikita´s Gift (D. Kaki x Roseyanka)
Roseyanka (D. Kaki x D. Virginiana)

And many others ussualy breeded in Ukraine.

Tropical Fruit Discussion / Re: Gomera Mango Seeds Finally !
« on: December 07, 2018, 04:26:56 AM »
Gomera/Turpentine can be found all over Florida. For hardier rootstock you should try la vernes seedlings from whomever is growing it in Socal or order a tree from them and fruit them.

According to this article Gomera 1 and Gomera 3 behavior differs from Turpentine, so not identical cv.

Cold Hardy Citrus / Re: Long term cold hardy citrus breeding project
« on: November 21, 2018, 11:19:34 AM »

For me, this is a little bit deceptive result and proves that even for a single gene trait you need more than 2 backcroses and 30 years of breeding in order to  get rid of nasty taste of Poncirus fruits.

I think, that the good taste is the last thing one can expect by crossing hassaku - nearly edible (more bitter than grapefruit) and FD - inedible.  :D

 I have a feeling, that I read somewhere, that Don  lost his plants because of frost and gave up the experiments, but maybe I'm wrong. But he is a member of so someone can try to contact him. Don_OKC

Interesting article about citrus indica, c. latipes and mactoptera.

Citrus General Discussion / Re: Winter Feeding of citrus
« on: November 12, 2018, 09:29:04 AM »
We don't fertilize in-ground citrus here after Aug 1st so we don't get late flushes during the winter than will get killed or damage.

Citrus may not go true dormant, but as a rule I don't feed any of my citrus after Aug 1st. Once the first freeze is predicted I move my container citrus into the garage & leave it there until March 1st. Left in the dark cool garage, it remain as it was put in, No new growth, no blooms & no leaf drop.

Normal years we don't get our first frost until mid / late December & usually only get 7-10 nights below freezing every year.

Here jn zone 6, the winter day is short and the only way, how not to kill citrus because of big disbalance of light/heat  is to keep temperature from 0 to 10 Celsius, no water, no fertilizer.

Ebay has it

All sellers except two, do not ship outside US, and those two sell it for astronomic price (with shipping) and do not have good reputation according to feedbacks.

Cold Hardy Citrus / Re: Yuzu... my new obsession!
« on: November 09, 2018, 07:12:45 AM »
As Millet correctly stated, big thorns are typical for juvenile non fruiting citruses.
I know only few cultivars, which have big thorns and fruits, one is Mandared.

To me it looks closer to citrus medica than citrus limon, or citrus latifolia etc. I put it in group citrus limonimedica.

Citrus General Discussion / Re: C35-Meyer lemon incompatibility
« on: November 06, 2018, 11:20:02 AM »
According to this paper:
Swingle citrumelo is incompatible with Meyer lemon.
C 35 is incompatible with Yen Ben lemon3, which died after 5 years in a trial at
Kerikeri, New Zealand.

So,  may be your C35 are in fact Citrumelo rootstocks.

According to this  Meyer doing well on C35.

« on: November 06, 2018, 06:21:39 AM »
Mayer is well known symptomless carrier of the tristeza virus, this was the reson for Improved Meyer lemon cultivar introduction. CTV causes
 quick declination, but you wrote, that you tested the plant. Sudden death because of the rootstock incompatibility is theoretically possible, when there is a long time deficiency of some chemical element, but for me it looks like poisoning.
Is there some other farm close to your? Did someone use herbicides close to you water source?

You wrote about poor root system because of incompatibility, it does not give me a sense, if rootstock does not want "cooperate"  with graft, it will push its own twigs to overgrow the graft.

Cold Hardy Citrus / Re: Parentage of a hybrid?
« on: November 01, 2018, 02:22:23 AM »
I should know the answer by now, but I know several of you can elaborate ad nauseum and enlighten me: When trying to create a citrus hybrid, does it matter which of the parent trees serves as the mother or father plant?
Yes it does matter.
So when the citranges were created via hybridization, which was the mother plant, the trifoliata or the orange?
Orange was the mother plant, just simple click on
When you see : X x Y (for example:Carrizo citrange  Citrus sinensis 'Washington' sweet orange X Poncirus trifoliata), X is mother.

Cold Hardy Citrus / Re: Yuzu... my new obsession!
« on: October 26, 2018, 03:25:48 AM »
In fact that scientific article about comparison is quite a nonsense, it is hard to compare yuzu.

I don't belive the article is a nonsense. It refers to Japanese yuzu, what is grown in Japan. Of course from yuzu there are many variations, but few cultivars. So what I looked is strictly Citrus junos. Sure if people start to grow it from seeds after 20 years we would have many variations. The seeded yuzu în Japan is mostly grafted with variations based on location.
There is one paper with yuzu and it's hybrids with DNA markers whuch list most used cultivars.

As I wrotte before :
3. each village has usually its own cultivar.
Lines are called kei

Important selections are:

1.木頭系(きとう)Kitō-kei (kitō)
3.早生種の「山根系」Yamane-kei  やまねゆず(はやしげる)Yamane yuzu (haya Shigeru)
The Yamane - kei was selected in Mr. Yamane 's garden in Anan City.  Fruits are large  and flat.
4.平の香(たいらのかおり)Hira no ka (tai-ra no Kaori)
seedling which seems to originate from Yuzu in Kinno village, Naka gun, Tokushima prefecture.
The shape of the fruit is somewhat height compared with the conventional type of Yuzu, and the concave ring around the fruit part protrudes considerably in a disk shape, the peel is yellow orange thick , the fragrance is strong.
5.物部系  Monobe-kei
6.種なしの (多田錦(ただにしき)) Tada nishiki

In Japan, there is a strong tradition to grow citrus from seeds.
For example parents sow the seed in backyard, when child is born and they know that when the child become adult, the tree will start to fruit.
For example, in Kochi prefecture you have at least 7 different yuzu (citrus junos) cultivars cited in scientific work marked as Kochi 1 .... 7.
