Take a look at this tomato wiki maintained by Tatiana. She also has beans, beets, carrots, lettuce, etc. I suggest setting up a wiki for Persimmons. Maybe contact Tatiana. I think she speaks Russian and perhaps Ukrainian as well as English.
Also add to the list are Dar Sofiyivky -20F that I am going to graft in April. Also the 2 hybrids PVNA from Cliff Costata X Rossey -20F, and Jerry Lehman Rossyanka male offspring OP -33F in Omaha, and Rossyanka male used to cross of the new hybrids.
‘Nikitskaya Bordovaya’ is an open-pollinated seedling of ‘Rosseyanka’
Gora Roman Kosh is an open-pollinated seedling of ‘Nikitskaya Bordovaya’
‘Pamyat Pasenkova’ (Memory of Pasenkov) – a sport (bud mutation) of ‘Rosseyanka’, characterized by better resistance to late-winter and early-spring frosts.
Clifford England has (2) males with his handwriting on the bags they state with quotes not italics:
“-22 Rosseymale”
“-11 Rosseymale” or I think he just writes “Rosseymale”
Jerry Lehman’s male that Tony and I will use is:
‘400-5’ hardy to at least -31 F.
Kuji Naja is one of the two hardy hybrid-PVNA’s of Cliff England. It’s edible when hard but only if it is pollinated. The other I don’t know the name but it is an astringent hybrid-PVA. Both are Costata x Rosseymale(s) that are of Cliff origin that David Lavergne used. Cliff planted both in a single hole and tagged each.
Richard, is it possible, similar to how peaches have a ripening date + or - relative to a particular variety (in the case of peaches it is Redhaven) , that we could add a column for that? I would say that comparing to Nikita’s Gift would be a great standard that everyone could relate to.
