ABSTRACT
The Solanum genus presents a great importance for research due to its economical importance being a great aim to different breeding programs. It is the best represented genus from the Solanaceae family, part of this family species producing tubers. Working method used in our experimentations was double node fragments culture. Our studies aimed regeneration and multiplication of four potato cultivars (Desirée, Redsec, Ts. 95-1161-66 and Ts. 94-1117-98) in order to improve the multiplication and pathogen free material obtaining protocols. Biometrical determinations performed for explants and new plantlets made possible to conclude as the best in vitro response was given by the cultivar Redsec both regarding the regeneration, growth and multiplication capacity and in foliar surface evolution, overcoming even the control (Desiree variety) and the cultivar Redsec can be recommended for other in vitro experimentations being a potent cultivar for this type of culture.
