In vitro reproduction of promising potato varieties for cultivation in the Кomi Republic

The paper deals with the results of clonal micropropagation of promising potato varieties for cultivation in the conditions of the Komi Republic. The study material is three potato varieties (Zyryanets, Pechorsky, Vychegodsky), characterized by the high resistance to late blight and abiotic stress factors in the conditions of the Komi Republic. The primary explants were weakly germinated eyeholes, as well as cuttings and shoot tips isolated from 14- and 30-day-old potato plants which underwent surface sterilization and then were cultivated in the Murashige-Skoog nutrient medium containing various hormones. The Pechorsky variety was identified to have the high growth index and specific growth rate of shoots in vitro. This variety can be included in studies on cell and genetic engineering aimed at creating potato forms with the complex resistance.
