Interesting:
Jerzy Piórecki in the Arboretum in Bolestraszyce near Przemyśl at the turn of the 1970’s and 1980’s. He collected the most valuable ecotypes found in south-east Poland, e.g. in Bolestraszyce, Prałkowce, Florianka, Wyszatyce. They became output material for obtaining the first Polish cultivars of cornelian cherry such as: ‘Bolestraszycki’, ‘Dublany’, ‘Florianka’, ‘Julisz’, ‘Kotula’, ‘Kresowiak’, ‘Paczoski’, ‘Podolski’, ‘Raciborski’, ‘Słowianin’, ‘Swietłana’, and ‘Szafer’
and from the same source:
‘Swietłana’ – seedling found in Ukraine. Medium-early cultivar, ripening
in mid-September. Large fruit (3.5 g, 2.4 cm in length), pear-shaped, dark
-cherry colour. Share of stone 14%. General-use cultivar, content of sugars
14%, acids 2.5%. Broad shrub, fast falling fruit.
The only data I have found is that the fruit is vividly red. Swietłana does not appear in any table. I will dig into the sources.
Per OGW: “An early ripening selection from the Kyiv Botanic Garden in Ukraine, Svitlana™ features good crops of large, very sweet and flavorful fruit. Disease-resistant and easy to grow, it is prized for its prolific display of yellow flowers in February, which are followed by abundant, dark red fruit in early fall. Formerly known by the cultivar name U-26.”
So it would seem there may be two Swietłana / Svitlana’s? Or is it that the seedling was found in Ukraine, and then raised and bred in Poland?
Many websites agree it comes from a polish arboretum: Cornouiller Swietlana - La Pépinière Du Fruitier

Kornoelje - Swietłana
But the polish ones say it is Ukrainian in origin (as do the English):

Disregard, I found my answer:
Variety grown in Bolestraszyce Arboretum. It was obtained by sowing seeds from a bush growing in Ukraine

Hurray!
