The main purpose of this research was to follow the minituberization process for 3 Romanian potato varieties, created at NIRDPSB Brasov. The biological material called “minitubers” is part of the first links of the national system of potato production for seed. The trifactorial experience of this research (3x2x2), on 3 repetitions, included the following factors: experimental factor A: variety, with three gradations: a1 - Marvis; a2 - Castrum; a3 - Ervant (considered control); experimental factor B: biological material used for planting, with two gradations: b1 - plantlets (considered control); b2- microtubers; experimental factor C: the volume of the nutrition space, with two graduations: c1-1.5 l (considered control) and c2- 2 l. The determinations were made for number and weight of minitubers/plant, in function of experimental factors. The average number of minitubers obtained/nutrition space was between 5.75 (Marvis variety) and 10.25 (Ervant variety), and the weight of minitubers ranged from 28.22 g (Ervant variety) to 93.53 (Castrum variety). By increasing nutrition is noted very significant positive differences for both analysed parameters.
