| Rootstock | M.7 EMLA |
Formerly known as EM VII. Selected in 1912 from unknown parentage at the East Malling Research station in Maidstone, Kent, England. Trees on M.7 EMLA produce a semi-dwarf tree about 60 to 70% as big as seedling. Trees are moderately precocious and may lean with some cultivars and may require trunk support. Trees tend to produce many rootsuckers. M.7 EMLA has been widely planted since the 1960s with cultivars such as ‘McIntosh’, ‘Empire’, ‘Cortland’, ‘Golden Delicious’ and spur strains of ‘Delicious’. Trees with cultivars such as ‘Gala’, ‘Stayman’, and ‘Granny Smith’ tend to lean excessively and require support. |
