In order to investigate the effect of variety, nutrion space on minitubers production, a study was carried out in the Laboratory of Vegetable Tissue Cultures of NIRDPSB Brașov, in period 202 -2022. The trifactorial experience (3 x 2 x 2), on 3 repetitions, included the following factors: experimental factor A: cultivar, with three gradations: a - Marvis; a2 - Castrum; a3 - Ervant (considered control); experimental factor B: year of study, with two graduations: b - 202 (considered control); b2 - 2022; the experimental factor C: the volume of the nutrition space, with two graduations: c - .5 l (considered control); c2 - 2 l. In this study Ervant cultivar stands out with a high number of minitubers (7.8 ), and the Castrum variety obtained the highest value of minitubers weight (75.65 g). The use of increased space for culture has a positive influence on minituberization, both in the number and weight of minitubers obtained/plant.
