In the years 2002-2004 the effect of dwarf rootstocks M.9, P.16, P.61, M.27, PB.4 and BW on the growth and early
stage of yielding of ‘Rubin’ apple trees was investigated. All the rootstocks were compared with M.9,
which was used as a model. After preliminary investigations on the basis of the trunk cross-section area the
rootstocks can be arranged in the following order of their growth vigour: BW (103%), M.9 (100%), PB.4 (97%),
P.61 (94%), P.16 (92%), and M.27 (59%). In the first two years of fruit bearing trees on the M.9 rootstock gave
the highest yield, these on PB.4, P.61 BW and P.16 a slightly lower one, while the lowest yield was obtained
from trees on M.27. The highest productivity characterized trees on M.9 and the lowest those on M.27.
