Aeroponics is eco-friendly, soilless technology for the cultivation of vegetable plants that can
be used for the production of pathogen-free pre-basic seed potato, namely minitubers. In
aeroponic modules, the underground parts of potato plants grow suspended in the mist of finely
dispersed nutrient solution to produce tubers, while the shoots grow above the module under
greenhouse conditions. This study aimed to evaluate the effects of the cultivar and origin of planting material on the minituber production in an aeroponic faility in Guča, Serbia. Two potato cultivars, Sinora and Agria, and two types of planting material, acclimated microplants
and plants originating from sprouted minitubers, were used in the study. Plants were grown in
the 2019 season with a planting density of 24 plants per m2 and ~14-day harvest intervals.
Agria plants of both plant origins steadily tuberized during most of the cultivation period and
formed a significantly larger number of minitubers (13.61) compared to cultivar Sinora (3.35),
which quickly completed the growth cycle. In both investigated cultivars, the mass of formed
minitubers was significantly higher in the plants originating from minitubers (18.80 g)
compared to plants of in vitro origin (9.04 g). Agria plants of minituber origin produced the
heaviest minitubers (19.05 g), while Sinora plants of in vitro origin formed the least heavy
tubers (5.29 g). The highest yield of minitubers, 6.26 kg m-2, was recorded for Agria plants of
minituber origin. The results of our study suggest that both plant origin and potato genotype
significantly affect minituber production in aeroponics.
