In 1981 ‘Smoothee Golden Delicious’ was established on M.9 rootstock trained as a trellis, and as free-standing trees on M.7 rootstock and the following 15 cm interstem combinations: M.9/MM.106, M.9/MM.111, O.3/MM.106 and M.27/MM.111. Trees on M.7 had the largest canopy volume and trunk cross-sectional area (TCA) and lower cumulative yield/ha. Trees on MM.111 with an interstem of M.27 were smaller than trees with an interstem of M.9. Trees on M.9 produced more fruit per TCA than any of the interstems or M.7 trees. The rootstocks and interstems had minimal effects on fruit size or biennial bearing tendency.
