Abstract: The research carried out is an attempt to combine the methods of plant biotechnology with conventional methods of selection, through comparative studies on the biological qualities of Helianthus tuberosus L. The nutrient media used are Murashige & Skoog and Quorin & Lepoivre. The influence of the chemical factors - IBA, TDZ, BAP and GA, in in vitro conditions for the induction of callusogenesis and regeneration was studied. The best morphogenetic ability in the leaf segments was observed in the variant with the participation of 1.0 mg/l TDZ, 0.07 mg/l IBA and 0.05 mg/l GA.
