Abstract
The paper presents results of experiments aimed at in vivo and in vitro propagation of Fabiana imbricata, an Andean evergreen shrub with impressive ornamental characteristics. Two ornamental types were studied: with white and with violet flowers. Both in vivo and in vitro propagation methods were successful. The mean rooting of the cuttings was 87%, and in some cases reaching 100%, but the growing season influenced considerably the cuttings’ production ability of donor plants. In the case of micropropagation, application of 0.2 mg l-1 BAP yielded more axillary shoots than higher BAP concentrations. The best regeneration of adventitious shoots from callus was obtained on medium with 1 mg l-1 BAP. Protoplast isolation was only possible from callus, because of the hard needle-shaped leaves of the species. The results proved that there are good opportunities for further breeding and use of this very promising ornamental in Europe.

Key words: breeding, new ornamental, propagation, Solanaceae
