This variety was obtained by crossing the 'Lyubskaya' variety with steppe cherry by amateur gardener M.F. Krivolapov (Shumikha, Kurgan Oblast). Study of the seedling and its transfer to state testing were conducted at the Sverdlovsk Fruit Breeding Station under M.G. Isakova. Originator — Sverdlovsk Fruit Breeding Station. Introduced into the State Register in 2004 for the Volgo-Vyat and Ural regions. Authors: M.F. Krivolapov, M.G. Isakova.
