The right choice of the culture medium is an important factor for micropropagation mainly because of the mineral component role during the regeneration process. This research was aimed at evaluating the effect of the MS/2, NN, WPM, QL and C2D culture medium on the establishment of nodal segments and multiplication of grapevine rootstock 'VR043-43'. The data was analyzed according to a randomized complete block design with four replications. The culture medium had no significant effect on the number of shoots per explant in the initial culture and subcultures. For the first subculture, the best number of microcuttings per initial explant was obtained using the MS/2, QL and C2D culture medium. For the second subculture no statistical differences were observed between treatments. Shoot height in the initial, first and second subcultures increased with QL culture medium. For the first subculture, 83.3% of rooting was found on shoots growing in the QL culture medium. The best results of shoot development for the initial culture of the grapevine rootstock of 'VR043-43' in vitro using nodal segments and its microcuttings multiplication were obtained with the QL culture medium.
