In spring 2002, nine clonal rootstocks: the German ‘Gisela 5’, the Russian ‘LC-52’, ‘OVP-2’, ‘OVP-3’, ‘VC-13’, ‘VSL-2’, ‘V-2-180’, ‘V-2-230’ , ‘V-5-172’ and Prunus mahaleb L. seedlings (control), were planted at a nursery of Polli Horticultural Institute and in late July the sweet cherry cultivar ‘Kristiina’ and three selections ‘Karmel’, ‘Polli 10/8’ and ‘Polli 6/2’ were budded on them. The highest bud take percentages were observed on V-2-230, OVP-2, and V-5-172. Incompatibility between ‘Karmel’ and several rootstocks was noted. The growth of one-year-old plants at the nursery was most vigorous on P. mahaleb seedlings, OVP-2 and OVP-3 and the weakest on VC-13. The trunk diameters of the clonal rootstocks were significantly smaller than those of the control rootstocks.
