The invention relates to a new and distinct virus-free variety of apple tree useful as a rootstock for supporting grafted apple varieties, particularly for planting of hedgerows of apple trees. The new variety originated as a clone of heat treated Paradis-Jaune-de-Metz selection, M9B, also called M9 INFEL. It has been found that there is better root lignification as well as generally several points of root issue on the clones as well as an increased vigor to the cultivars.
