MM.111 Apple Rootstock (Spring 2022)


A semi-standard, rugged apple rootstock . Also known as Malling-Merton 111, MM.111 EMLA, EMLA 111.

MM.111/MM.111 EMLA is a semi-standard rootstock, a cross of Malling 2 and Northern Spy that produces trees about 85% of full size. Its major strengths are pest and disease tolerance (collar rot, fireblight, and WAA), and its tolerance for heavy, wetter soils. It produces upright and vigorous trees that are cold hardy and self-supporting. Unfortunately, MM.111 is slow to come into production and it is not productive. It is quite prone to burr knots.

We have had consistently good results using MM.111 as the base for a 3-piece tree–the classic interstem. Anchorage remains good in this scenario and productivity issues are resolved. Spur-type Delicious trees have performed well, and Tomato Ringspot Virus has not been a problem.
