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 65% of the size of like apple trees growing on seedling rootstocks. Compared to its M9 parent, this new clone produces many more and larger lateral branches, has more sharply serrated leaves which are more pale yellow-green in color. The clone is also more vigorous and produces a large number of rooted plants in a given area of stoolbed.
