ABSTRACT:
This invention relates to a new and distinct apple tree rootstock clone which is useful as a size-controlling rootstock. The new clone originated as a mutation of Malling 9 (M9), an unpatented dwarfing apple rootstock, Standard growing apple cultivars propagated on this new rootstock are approximately 70 % of the size of like apple trees growing on apple seedling rootstocks. In the stoolbed the clone produces few lateral limbs, large round to oval leaves with broadly acute tips and possesses a pronounced, profuse blooming characteristic. The clone produces a larger number of rooted plants in the stoolbed.
