Abstract

A new and distinct spur-type variety of McIntosh apple tree is provided which exhibits an extreme degree of dwarfness. The new variety was produced as a single limb mutation in a fifty year old standard McIntosh apple tree. The tree possesses an extremely compact, strong and rigid structure and bears fruit which is less intense in color than other spur-type McIntosh apple tree strains such as the Gatzke strain (non-patented), the Greenslade strain (U.S. Plant Pat. No. 2,982), and the Raikes strain (U.S. Plant Pat. No. 3,390).
