Aeroponics is modern, soilless technology for potato cultivation that promotes the production
of a large number of healthy minitubers (pre-basic seed potatoes). In aeroponics, roots and underground
stems (stolons) of potato plants grow inside closed boxes (modules), suspended in the fine mist of a
nutrient solution that recirculates through the system. As a result, a significant number of tubers larger
than 1 cm can be formed on stolons during the growing period. The aim of this study was to evaluate
the effects of the genotype and origin of planting material on the production of minituber in an aeroponic
facility in Guča, Serbia. Our study encompassed three potato cultivars: Cleopatra, Kennebec and
Désirée, and two types of planting material: acclimated microplants and plants originated from the
previous season’s minitubers. Plants were aeroponically cultivated in the 2019 season (late May-
December) with a planting density of 24 plants per m2 and ~14-day harvest intervals. The largest
number of minitubers per plant (19.9) was recorded for cultivar Désirée, followed by the Kennebec
(15.7) and Cleopatra (11.1). The average mass of minitubers of all the cultivars under consideration
was significantly higher in the plants originating from minitubers than in plants of in vitro origin. The
highest yield of minitubers, 10.27 kg m-2, was recorded for Kennebec plants of minituber origin.
Besides, the plants originated from minitubers steadily tuberized during the entire cultivation period
in the aeroponic facility.
