Damil GM 61/1 is a low vigorous vegetative sweet and sour cherry rootstock that originates from the decorative sweet cherry Prunus dawyckensis Sealy. Cultivars grafted on this rootstock have low vigour, the crown is more open and markedly more productive, the fruit mass is more pronounced, and fruits are more intensively coloured. Aiming at developing efficient protocol for in vitro propagation of this very popular low vigorous rootstock, the influence of type and concentration of plant growth regulators on multiplication and rooting phases at constant microelements, macroelements and vitamins concentration, according to Murashige and Skoog (1962) (MS) was studied. The highest multiplication index (1.96) was found on MS medium with in mg/l: BAP 0.5, IBA 0.1 and GA3 0.1, while the highest rooting rate (50%) was obtained on the hormon free medium (HF) which included a pretreatment (5-minute treatment) of the basal part of the shoots with the NAA at concentration 100 mg/l.
