Dwarf apple rootstocks M 9, M 27, Pajam 1, Pajam 2, Jork 9, J-TE-E, J-TE-F, J-TE-G and J-OH-A were evaluated in a trial conducted in an experimental orchard with cultivars Golden Delicious, Gloster and Melrose. The experimental plantation was established in 1990. Data on: yield (kg/tree), yield efficiency (kg/cm2), trunk cross-section area and suckering were recorded during the period 1991–2000. The cumulative yield per tree was highest on Jork 9 and Pajam 2. Trees on Pajam 1 and M 9 also had good productivity. Yield efficiency was highest on Jork 9, followed by M 27 and J-TE-G. Trees on Pajam 2 were most vigorous. The tree size on M 9 was similar like on Pajam 1. Trees on J-TE-E and J-TE-F grew less than those on M 9. The weakest growth was observed on rootstocks M 27 and J-TE-G. Among the tested rootstocks, J-OH-A produced the highest number of suckers. Suckering was more intensive with Melrose followed by Gloster and Golden Delicious.Keywords:
