In the world of orchard science there is a trend of constant limiting the size of fruit trees of almost all species. That is why there is a continuous search for new rootstocks reducing the vigour of growth of the cultivated plants. The experiment was conducted at the Experimental Station of the University of Life Sciences in Poznań, in the years 2008–2009. The aim of this study was to estimate of 15 clones obtained by crossing A2 × B.9 rootstocks to check their usefulness for the production of maiden apple tress of ‘Galaxy’ and ‘Rubin’ in a nursery. M.9 and M.26 rootstocks were used as a standard. The strongest growth of maiden apple trees was obtained on M.26 rootstock and on the clone number 15. The growth of trees on clone number 5 was weaker than those on M.9 rootstock. Maiden apple trees of ‘Rubin’ cultivar did not create lateral shoots for most rootstocks. The biggest number and total number of lateral shoots was found on the trees of ‘Galaxy’ on rootstocks clones number 1, 3, 6, 7, 10, 13 and 15 and the least on clones number 2, 5 and 9. The biggest number of skeleton roots had trees on M.26 rootstock and the fewest on M.9 one. The biggest number of maiden trees in comparison with the budded rootstocks was obtained for clones number 6, 10 and 13 and the fewest for clones number 2, 7, 8, 9 and 11. For all clones the percentage of trees meeting the requirements of the standards was high and the results did not differ from those on M.9 and M.26 rootstocks.
