The results of studies on rooting in vitro of European cranberry Oxycoccus palustris Pers. plants of Dar of Kostroma cultivar and hybrid form 1-15-635 during clonal micropropagation on a WPM 1/4 nutrient medium and its adaptation to non-sterile conditions. With an increase in the concentration of IAA from 0.5 to 1.0 ml/l and with the addition of Ecogel at a concentration of 0.5 mg/l the number of roots of European cranberry plants of the Dar of Kostroma cultivar increased by 36.7 %, of the hybrid form 1-15-635 – by 7.4 % at the stage of rooting in vitro. Substrates from high-moor peat are used with the addition of mycorrhizal-type ecological preparations (Mycorrhiza, Biomikoriza, Mycogel) at the stage of adaptation of European cranberry to non-sterile conditions ex vitro. The maximum survival (98–100 %) of cranberry are observed when using a peat substrate with the addition of Mycorrhiza. The timing of transplantation had a significant impact on the survival rate of cranberry plants. The best survival rates (84–86 %) are observed in plants of both cultivars transplanted in May. The survival rate of plants is high (92–96 %) in the first year of cultivation after transplanting European cranberry to a high-moor peat plot under natural conditions. Yield data has a high values.
