Popis:	The effects of rootstock and interstock on the performance of scion apple varieties McIntosh and Cortland were studied over a 17-year period. The clonal interstocks Hibernal and M. robusta 5, the seedling rootstocks Anis, Antonovka, and McIntosh, and the clonal rootstock M. robusta 5 were used in all possible combinations.The yields of both scion varieties were significantly greater on Hibernal interstock than on M. robusta 5 interstock. Scion rootstock interaction was also significant, since McIntosh yielded better than Cortland on Anis rootstock, whereas Cortland gave the higher yield on M. robusta 5 rootstock. The yield of McIntosh–Hibernal–Anis was significantly greater than that of any other combination but Cortland–Hibernal–M. robusta 5. Seedling McIntosh was the least satisfactory rootstock.Yield was not correlated with circumference of interstock. Variability in the latter was not reduced by the use of clonal rather than seedling rootstocks. No combination resulted in trees smaller than standard size.
