ABSTRACT:
This invention relates to a new and distinct apple tree rootstock clone that originated as a mutation of Malling 9 (M9). Standard growing apple cultivars propagated on this new rootstock are approximately 65% of the size of like apple trees growing on apple seedling rootstocks. Compared to its M9 parent, this new clone produces many more and larger lateral branches, has leaves with acute tips and has more sinuate serrations. The clone is also more vigorous and produces a larger number of rooted plants in a given area of stoolbed.
