- ‘Rosseyanka’ (‘Россиянка’ in Russian) = D. virginiana × D. kaki
- ‘Nikitskaya Bordovaya’ (‘Никитская бордовая’ in Russian) = OP seedling of Rosseyanka. More specifically: “Nikitskaya Bordovaya was obtained from selection in progeny of first back-cross (D. virginiana × D. kaki) × D. kaki, where D. kaki was represented by a mixture of pollen from several highly heterozygous varieties” (“Никитская бордовая получена в результате отбора в потомстве первого беккросса на видовом уровне – (D. virginiana × D. kaki) × D. kaki, где рекуррентные D. kaki были представлены смесью пыльцы нескольких высокогетерозиготных сортов”).
- ‘Kolhoznitsa’ / ‘Kolhospnytsia’ (‘Колхозница’ / ‘Колгоспниця’ in Russian / Ukrainian) = ‘Nikitskaya Bordovaya’ × D. kaki
- ‘Dar Sofiyivky’ (‘Дар Софиевки’ in Russian, ‘Gift of Sofiyivka’ in English) = OP seedling of ‘Kolhoznitsa’ (aka ‘Kolhospnytsia’). More specifically about pollen parent: “in the orchard, the trees of ‘Kolhoznitsa’ grew near blooming trees of choice varieties of D. kaki (mostly those with a good degree of winter hardiness) and best, by winter hardiness, early ripening and flavor, hybrid varieties” (“в саду рядом с деревьями Колхозницы росли и успешно цвели отборные (преимущественно достаточно зимостойкие) формы D. kaki и лучшие по зимостойкости, раннеспелости и вкусовым качествам плодов гибриды D. kaki с D. virginiana”).
Varieties obtained as ‘Nikitskaya Bordovaya’ × D. kaki and characterized by lower winter hardiness than ‘Nikitskaya Bordovaya’:
‘Novinka’ (‘Новинка’ in Russian, ‘Novelty’ in English), ‘Gora Goverla’ (‘Гора Говерла’ in Russian, ‘Mount Hoverla’ in English), ‘Gora Rogers’ (‘Гора Роджерс’ in Russian, ‘Mount Rogers’ in English), ‘Gora Roman-Kosh’ (‘Гора Роман-Кош’ in Russian, ‘Mount Roman-Kosh’ in English), ‘Konicheskaya’ (‘Коническая’ in Russian, ‘Conical’ in English), ‘Ovalnaya’ (‘Овальная’ in Russian, ‘Oval’ in English), ‘Pamyati Chernyaeva’ (‘Памяти Черняева’ in Russian, ‘Memory of Chernyaev’ in English).
Varieties obtained as ‘Nikitskaya Bordovaya’ × D. kaki and characterized by higher winter hardiness than ‘Nikitskaya Bordovaya’:
‘Bozhii Dar’ (‘Божий дар’ in Russian, ‘God’s Gift’ in English), ‘Kolhoznitsa’ (‘Колхозница’ / ‘Колгоспниця’ in Russian / Ukrainian, '‘Collective Farm Women’ in English), ‘Odnodomnaya’ (‘Однодомная’ in Russian, ‘Monoecious’ in English), ‘Seedling 3/1’ (‘Сеянец 3/1’ in Russian).
Varieties obtained as ‘Nikitskaya Bordovaya’ × D. virginiana and characterized by higher winter hardiness than ‘Nikitskaya Bordovaya’ and ‘Rosseyanka’:
‘Sosnovskaya’ (‘Сосновская’ in Russian), ‘Chuchupaka’ (‘Чучупака’ in Russian), ‘Universal’nyi’ (‘Универсальный’ in Russian, Universal in English), ‘Seedling 12/11’ (‘Сеянец 12/11’ in Russian), ‘Seedling 12/21’ (‘Сеянец 12/21’ in Russian), ‘Seedling 15/5’ (‘Сеянец 15/5’ in Russian). ‘Seedling 15/5’ had the best winter hardiness of all varieties mentioned above, it not just survived the extremely cold winter of 2005-2006, but produced a full crop.
