FIELD: biotechnology.
SUBSTANCE: proposed method for healing potatoes from viral infections in vitro involves planting aseptic apexes measuring 2.0-4.0 mm on Murashige and Skoog nutrient medium without phytohormones, comprising antiviral substances (ABB). A distinctive feature of the method is that a mixture of kappa and lambda carrageenans is used as ABB in a ratio of 70:30, added in an amount of 1.0 g/l of medium, with a duration of explant cultivation of at least 100 days.
EFFECT: making potato microplants free from M, L, S viruses in in vitro culture by using carrageenans as an antiviral agent.
