This year I have grafted 2 Ukrainian varieties
schistian gold and Kolhoznitra. We will see.

The paper covers that already. It’s seems up to date…
The existence of a non-astringent persimmon cultivar of Chinese origin, ‘Luotian-Tianshi’, was first reported by Wang (1982); it had been previously believed that no non-astringent cultivars of Chinese origin existed. Its distribution was within a narrow area extending from Hubei Province to Henan Province. Subsequently, several other non-astringent cultivars, including ‘Tianbaogai’ (former name, ‘Baogai Tian Shi’), were found (Yonemori et al. 2005).
Are you referring to Nikita’s Gift? What is the name of the other PCNA? What are their names in russian?
Which 2 PVNA hybrids are you referring to that are in EU and USA? I saw a post mentioned in the past where you bought your JBT-06 and other hybrids from England Nursery. Does that mean that England Nursery has these 2 PVNA hybrids?! You have me excited if these cultivars are already stateside.
Where did you buy your Luotian Tianshi from?

There’s no point in getting excited.
I am much less interested in persimmons than in the past … There is a moment you have to turn the page. It takes up a lot of space and I’m the only one. Eat the fruits.
In recent years I have lost a lot of varieties due to drought and feral pigs. I see it differently.
So I must have lost at least 80 varieties of persimmons I think. JBT 6 is one of the lost varieties.
I wonder how many people outside of China and Japan have Luo TIAN TIAN SHI.
How did he get to my place? … that’s a question.
I think I ordered it from Santa Claus. You always have to believe in it and it happens at the foot of the tree.
Seriously, a guy asks you how you seduced your wife and how to seduce her, you gonna tell him!
We are all collectors. We all know each other.
We all have specialties, and we use the specialties of our friends to progress and vice versa. It’s simple.
For Russian varieties it is the Nikitsky research center.
I’ll admit that I also look at genetics and statistics.
But if I was interested in persimmon it is precisely because you learn about this species every day.
For example, one of the current PVNA hybrids has neither parent that carries the non-astreingent gene. How do you explain it with the statistics. …

This is a good point. My attempt to work out some probabilities was an admittedly crude approximation based on simplifying assumptions. The genetics of astringency may be more complicated than assumed. Also, I didn’t even factor in the genetics of cold-hardiness. The odds of a cold-hardy AND non-astringent cross would be 1/20 x 1/20 = 1/400 – or worse if cold-hardiness is driven by multiple genes, which it probably is.
All this from someone who admits to having no formal training in genetics.
That’s a shame about the feral pigs.

I have friends and or family overseas that could send me varieties located in Japan and China such as luotian tianshi. UPS overnight. There are plenty of scion trading clubs and groups (visa vie FB) that share propagation material without much regard for border controls. I was just kind of hoping you would tell me that they were purchased from England or some other stateside nursery. If I was less squeamish about being possibly responsible for a outbreak of plum pox virus and circumventing quarantine requirements, I would just ask my family to UPS overnight prunus persica scion from France for a few heirlooms that I’ve been trying to track down. 
The explanation is simple. There are three possibilities. In two of the scenarios, the genetics analysis was incomplete; either the parent has the gene or the progeny doesn’t. The last possibility is a mutation, but the likelihood of a point mutation occurring in the exact ast locus needed for the intended attribute targeted in the cross is arguably smaller than the likelihood of human error in the original analysis. (It also raises the competence of the original breeder - why you would use known two homozygous parents and assume you’d produce a heterozygous progeny.) In most cases as you pointed out, they didn’t even know or keep track of the D. virginiana pollen donator for the D. kaki x D. virginiana hybrids.
I’d still like to know the name of the purported 2 PVNA nonastringent hybrids you mentioned are in the EU and US. As far as I know (and when I recently checked with Cliff), anything that has made its way here recently, Gorvela series, Sestronkaora series, Sestronka, Sovietski, etc… are all astringent.

I looked at the import requirements, and they’re actually not too bad for most plants (peaches may have some extra restrictions). Basically, you need to have it mailed to inspectors at a pot of entry, who then forward it to you. Then you just need to keep them 10’ away from other plants for 2 years and be willing to be inspected, and report if any die.
@Arhus76 if you let us know what those PCNA hybrids are, there are many people who would be interested in importing them legally

Beautiful! We definitely need this variety in the US.

Amazing. Do you know of any suppliers besides Limbach (Persimmon Tree (Diospyros kaki) DAR SOPHIEVKI)? I’d love to add one to my garden in Germany.
I will be selling wood this winter.

Great! Should is message you later in the year? I’m not very experienced with grafting, but I’d like to give it a shot.
As far as I know, it is already available in the USA.

Hello Harbin, wondering if you will or know anyone who will be able to ship scion wood of this cultivar to Canada with phytosanitary certificate… or can even point me in the right direction that would be great.
I haven’t seen any reports of it being grown, but I could easily have missed it. Do you know of someone growing it?

I know Cliff England has a few.

Interesting. He hadn’t heard of it when I emailed him last year, but maybe he acquired some since then.
Yes, it is new. He has not even grafted any into his orchard yet.

Hi Pavel,
Thanks for posting your pictures. I read about this variety but I could not find an article that describes its classification. Do you have to know the parentage of this hybrid?
