There was carried out a comparative study of potato minitubers yield obtained from in vitro potato plants in greenhouse and in aeroponics. Three cultivars of in vitro-plants were used in the experiment. According to the results, the survival of in vitro-plants obtained in the aeroponic system was 7–10 % higher than in the greenhouse. The minitubers obtained in the aeroponic system were mostly characterized by a small size < 25 mm (61–73 %), whereas the size of the majority of mini-tubers obtained in the greenhouse exceeded 25 mm (63–81 %). The number of minitubers produced per square meter was two to three times higher from aerial products than those obtained by the traditional method. However, the differences between the total yields by weight were insignificant, due to the much greater weight of minitubers produced in the soil. The results of this study showed that the aeronautical system is a viable technological alternative to the component of minitubers production in the soil.
