Blackcurrant Memory of Zhuchkov

Blackcurrant Pamyat Zhuchkov is a representative of plants with a mid-late period of fruit ripening. A subspecies appeared in the St. Petersburg GAU (LSHI), thanks to the works of the scientist-breeder E.I. Glebova, by pollination of the Altai Stakhanovka currant subspecies with a mixture of pollen of such varieties as Exhibition... For quite a few years, this subspecies was considered the leading industrial subspecies in the Leningrad Region.
