Clonal selections of Prunus aviumL., Prunus mahalebL., and P. aviumx P. mahaleb(M x M) were compared during an 11-year period with mazzard seedling or mazzard F 12/1 as understocks for Prunus aviumcvs Napoleon, Bing, Lambert, Corum, Chinook, or Sam. There were no obviously incompatible combinations but certain stocks produced smaller trees than others. Trees on P. mahaleb193701 and 163091 were slightly smaller at age 10 than controls, but the difference varied with site and cultivar. Trees on M x M 14 were 1/3 to 1/2 the size of controls after 11 years. Trees on OCR-2 were the same size as control trees but were more precocious. Trees on M x M 39, were dwarf and precocious but did not remain productive.
