Past research has shown that apple cultivars do not perform equally on all rootstocks. For this reason, the growth and production efficiency of various stock scion combinations were evaluated during the past 10 seasons. In 1966 a planting of 15 cultivars on MM-106 and M26 was established at the Eastern Ohio Research and Development Center near Caldwell, Ohio. The trees were planted in contoured rows with M26 spaced 12' x 18' and MM106 18' x 18'. The trees were staked and trained to a central leader and maintained with standard orchard practices. The planting contained 12 to 20 trees of each cultivar on each rootstock, arranged in 20 incomplete blocks with each block containing both rootstocks. Yield and trunk circumference were taken annually, and, in 1976 canopy height and spread were determined.
