Features of seasonal development of black currant (<i> Ribes nigrum</i> L.) in the Arctic zone of the Russian Federation

Black currant is the most valuable berry crop of Murmansk Province in terms both biological properties and adaptive qualities necessary for growing difficult agroclimatic conditions North. Every year, a search carried out varieties forms with best indicators winter hardiness, yield, disease resistance environmental friendliness, order to identify accessions economic traits. The objects present study were 24 cultivars black different ecological geographical origin obtained 2015 from collection N. I. Vavilov All-Russian Research Institute Plant Genetic Resources (VIR). Studies 2017-2021 at Polar Experiment Station, branch VIR. care plants was provided according agricultural practices developed crops Region. results five-year phenological observations assessment hardiness studied showed that onset vegetation all occurred annually second decade May, flowering June, maturation third July, growth shoots ended first September. combined into groups (highly winter-hardy winter-hardy), as well phenophases (early, medium, late), ripening dates mid, late-ripening). Early noted ‘Pigmei’, ‘Izyumnaya’, ‘Rita’, ‘Volshebnica’, ‘Vasilisa’, ‘Almiai’, ‘Kriviai’, ‘Mila’, ‘Poklon Borisovoi’. observed ‘Severnoe Siyanie’ (C), ‘Kriviai’. late maturing are ‘Slavyanka’, ‘Kipiana’, ‘Gratsiya’, ‘Chudnoe Mgnovenie’. numerous group mid-ripening (64 %), followed by early (20 ones (16 %). All high adaptability Province. They had time enough form complete fruiting before frosts. Due five years research, they can be recommended cultivation Arctic zone Russian Federation.
