The growth, productivity, and anchorage of ‘Starkrimson Delicious’ and ‘Gardiner Delicious’ apple trees on M.7A, M.26, M.9/MM.111, M.9/MM.106, and MM.111 rootstocks and rootstock-interstem combinations were assessed. ‘Starkrimson’ (spur strain) trees were smaller, more productive per tree, more efficient, and produced higher theoretical yields per hectare than did ‘Gardiner’ (standard strain) trees. Trees on MM.111 were the largest, least productive (per tree), least efficient, and produced the lowest theoretical yields per hectare. However, they were much better anchored than any other rootstock or rootstock-interstem combination.
