There is always the possibility of disjunct meiosis where the chromosome count winds up different than the parent tree. A hexaploid pollinated by a diploid would result in a tetraploid. This is unlikely but not impossible. It is also possible for a tetraploid to naturally convert to a hexaploid. But the most likely explanation is that there are a few hexaploid persimmons scattered through the southeast. Nobody realizes they are hexaploid. It is also possible that a female persimmon occasionally produces a male flower.

In truth I donāt know if my 60/90 statement on pollination with hybrids is true or not, but thatās what they say for the americans and it would make sense for the hybrids. As for the americans some varieties throw random male flowers. I have some other hybrids that will fruit for the first time this year, so we will see if they are seedless or not.
Lucky I believe is in the 60 area. My Rosy has been seedless so far.
Itās also possible that there are random 90ās in the south wild from many years of people planting them.

I found this image helpful, because I heard AR only has 60c DV- since itās in the south. But thatās not the case. Look at MS and LA! We probably have both here judging by neighboring TN. Iām sure more sampling would lead to a more complex map.

What kind of potting mix do yiu have? I ended up grabbing a tam kam from Madison citrus nursery
I got used to making a home-made mix while growing figs. I make 10 gallon batches: Roughly 4 gallons of peat, 4 gallons of composted leaves and grass, 1 1/2 gallons of calcined clay, 1/2 gallon of diatomaceous earth. Then I mix in 2 cups of dolomitic limestone, 1 cup of gypsum, 1 cup of wood ash, a cup of crushed shells, and a handful of 10-10-10.

The data used to make that map came from 45 trees in Kentucky and a 1941 study where āsingle-tree collections of seedsā were grown out and tested. I would take those ranges as nothing more than a vague suggestion until more extensive sampling is done.

so similar to figs works? for figs i use like 1/4 wood chips 1/4 perlite 1/4 sand 1/4 compost And I add in my osmocote which has full nutrients (its a bulk version)
I didnāt bother looking that deep. Are there better datasets available?
I donāt see why not.
For my taste, your mix is way too heavy on perlite, which is expensive and tends to separate from the mix then fly away; and sand which is heavy, non-absorbent, and unable to hold nutrients. Calcined clay and diatomaceous earth are both water-absorbent and nutrient-retentive (high CEC). You can buy 40-50 lb bags in auto supply stores where they are sold to treat oil spills in garages.
A mix that is 30% CC and DTE will drain well while retaining water and binding nutrients.

How old is the tree? Has it flowered before?
Not yet - this will be 3rd year in ground, itās relatively large. My much smaller ikkj has flowered two years now.
I am in what is generally considered to be the 60-C area. That said, Iāve been growing 90-C persimmons here for 30 years, including several members of the Early Golden family, and planting seeds from 90-C females for use as rootstocks. IDK if there was already a 90-C male in the vicinity, but I know some seedling trees that either didnāt get grafted or lost their graft, have bloomed out as males. I also have the F2 RosseyMale from Clifford England, Claypoolās F-100 polygamodioecious male, and now Jerry Lehmanās 400-5 male (seedling of Rosseyanka) contributing to the pollenation soup here.
JT-02 has been totally seedless for the 3-4 yrs of fruit it has produced. Maybe 1 in 20 Rosseyanka fruits have (usually one) seed, Davidās Kandy Kornā¦ probably 50% have seeds, though usually only 1-3, and they are very slender. Other hybrids have not yet fruited.
Yates and Prok are variably seeded - many seedless fruits, but some with one or a few.
NC-10 (a member of the Early Golden family) is fully seeded, and has been since it began fruiting back in the late 1990s. John Rick, 816(which may be Meader) and others all generally have a full complement of seeds in their fruit, here.
My graft of SFES, which is a confirmed 60-C local selection, behaves just like the ortet - produces mostly small seedless fruits, with up to 20% being 50% larger, and bearing a single plump seed. Given my location, Iām sure there are probably ample numbers of 60-C males on neighboring properties.

Here I suspect that I might have both 60 and 90 wild. Hybrid has been seedless and americans have had 1-3 seeds. Wilds are straight up bags of seeds. We seem to be getting mostly similar seed counts and you can confirm you have both 60 and 90. That makes me have to ask the question. Why are hybrid for the most part seedless and why are americans (most varieties) not bags of seeds like the wilds?

My Prok is looking good this year.
I have not tasted Prok yet.. the last two years at Englands Orchard mid October Prok and H118 were done already.

My Dar Sofiyivky has this drooping growth, is this normal? Been well above freezing since budding out but not exactly warm either in my southern-sweden maritime climate with temperatures around 10C/50F last few weeks.

Iād be happy with that.

Yes, this looks like normal growth for a Persimmon.
