Popis: In the laboratory for micropropagation in Potato Research Center in Gucha, in vitro virus-free plants of following potato varieties were produced: Desiree, Kennebec, Agria, Cleopatra and Sinora. Acclimatized and rooted plants were transplanted in previously prepared aeroponik module. During the duration of the experiment, the mini-tubers were successively harvested four times and their mass and number were recorded. The first harvest of mini tubers was out after 40-45 days after transplanting in aeropnik system. The highest average number of mini tubers was of the Desiree variety (15.55), while the lowest number was harvested by varieties Sinora and Cleopatra (10.66 and 10.52). The highest average mass of one mini-tuber per plant was obtained in the Agria variety (8.97 g), followed by the Kennebec variety (7.61 g) and the Kleopatra variety (6.36 g). The smallest mini-tubers were measured in the Desiree and Sinora varieties (5.32 g and 4.83 g). In the aeroponic system, 4.08 times more mini-tubers were obtained compared to the substrate. Aeroponik system offers the potential to improve the production of potato mini tubers. U laboratoriji za mikropropagaciju Centru za krompir u Guči proizvedene su bezvirusne biljke in vitro sorti krompira: Desiree, Kennebec, Agria, Cleopatra i Sinora. Aklimatizovane i ožiljene biljke presađene su u pripremljene aeroponik module. Tokom trajanja ogleda mini krtole su sukcesivno ubirane u četiri termina i merena je njihova masa i broj. Prvo branje mini krtola je obavljeno posle 40-45 dana po presadjivanju u aeropnik sistem. Najveći prosečan broj mini krtola imala je sorta Desiree (15,55), dok su najmanji broj dale sorte Sinora i Cleopatra (10,66 i 10,52). Najveća prosečna masa jedne mini krtole po biljci ustanovljena je kod sorte Agria (8,97 g), zatim kod sorte Kennebec (7,61 g), odnosno sorte Cleopatra (6,36 g). Najsitnije mini krtole izmerene su kod kod sorti Desiree i Sinora (5,32 g i 4,83 g). U aeroponik sistemu dobijen je 4,08 puta veći broj mini krtola u odnosu na supstrat. Aeroponik sistem nudi potencijalnu mogućnost za poboljšanje proizvodnje dobijanja mini krtola krompira.
