`Schmidt' and `Bing' sweet cherries were planted in 1982 at the W.S.U. Royal Slope orchard near Othello, Wash. `Schmidt' was on Mazzard × Mahaleb (M × M) rootstocks 39, 97, 14, and Mazzard seedling. `Bing' was on East Malling (E.M.) cherry rootstocks 38, 15, 21, 16, 50, and Mazzard and Mahaleb seedling. Yield of `Schmidt'/M × M 39 was greater than all other rootstocks. Trunk diameters of `Schmidt' were greatest on Mazzard and M × M 39. If a standard-size tree is desired, M × M 39 may be useful. `Bing' trees on the E.M. rootstocks tended to be larger than on Mazzard or Mahaleb and are, therefore, not of great interest.
