In the nursery new rootstock for maiden apple tree was compared with standard rootstocks: M-9, P-2, M-26. The number of the obtained maiden apple trees of Delikates on new rootstock was higher than on P-2 and M-9 rootstocks but lower than on M-26. There were no differences in this parameter between the examined rootstocks in case of Elstar cultivar. The height of maiden apple trees of Delikates and Elstar on new rootstock was similar to the height on M-9. Maiden apple trees on new rootstock were significantly thicker than the ones obtained on other rootstocks. The average sum of the length of long shoots and their number on one maiden tree for the new observed rootstock was radically bigger than on M-9 and M-26 rootstocks. The consistency of the maiden apple trees with the Polish Rules did not differ significantly for all examined rootstocks
