Characteristic Detail Description
Rootstock M.27 EMLA

Selected in 1934 from a cross of M.13 x M.9 at East Malling Research station in Maidstone, Kent, England and was tested as Malling 3431. M.27 EMLA is a very dwarfing rootstock and is probably too dwarfing for most commercial situations except for vigorous cultivars on vigorous sites, but it might be considered for home gardens where a small tree is desirable.. Trees on M.27 EMLA are very precocious and productive and require permanent tree support. This rootstock has been evaluated in several NC-140 trials and trees are about 30 to 50% as large as trees on M.9 NABT 337. M.27 EMLA is highly susceptible to fire blight and fairly resistant to crown and root rots. M.27 EMLA produces few burr knots and root suckers.
