I have male diospyros lotus tree and i am wondering is it possible cross pollination between d.lotus and diospyros kaki (Asian persimmon)?.
And what will be results of that pollination?, seed in fruits?.
Both variety blooms in same time so i suppose they should be able to cross pollinate.
Very unlikely that they could pollinate each other
There is a ROJOBRILLANTE x LOTUS hybrid
Here is some info a friend gave me on the Lotus hybrids
Hello Daniel,
For hybrids with D. Lotus, to my knowledge only two exist or have existed. The Russian had made a hybrid Kaki X Lotus. I was told they had given up.
This type of cross is subject to discussion because D.Lotus has a chromosome. D. Kaki 90 chromosomes and D. Virgininia 60 and / or 90 chromosomes.
In China there will be D. Lotus with large orange fruit. There would be 2 in France too. That’s D. Lotus would be Lotus Hybrids / khaki. the number of chromosomes should allow hybridization.
For the ROJO BRIANTE X LOTUS, it would have been created in Portugal. I got it from a contact in Spain. It is not diffussed.
The description that is made is: Non-astringent fruit (which amazes me to see the parents), size of a tangerine and color rather to orange red.
I grafted in spring 2017, so not yet seen the fruit.
However, it is the variety that has resumed most quickly on D. Lotus. Very good compatibility. Khaki leaf. Medium to strong growth.
I have found this information’s about hybridization kaki 
I read the same thing, the hybrids really interest me . Especially interspecific hybrids. The introductions of new hybrids allow us to play around with more genes and if the RB x Lotus hybrid is real it may open many new doors if fertile.
Nikitskaya Bordovaya is the variety known as Nikita’s Gift in the U.S. Bordovaya means wine-red colored (like bordeaux) in Russian.
There is also a Nikitskaya Bordovaya no2
D. kaki x D. lotus = “successful, but not rewarding”. To me that just means that the F2 and F3 generations are where the rewards would happen. That is often the case. In the first generation you just get a 50:50 cross, but in the second and successive generations you can get enough mixing that some plants will possess certain traits from one species or the other like perhaps the full hardiness of D. lotus and the full large fruit size of D. kaki.
