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.
Claims1
A new and distinct apple tree clone, a sport of the Malling 9, referred to by the cultivar designation `M9-RN8`, substantially as herein shown and described, characterized particularly by its ability to serve as a rootstock for grafting of apple tree cultivars to produce dwarf apple trees and by its ability to rot very readily in the stoolbed with very little lateral branching and produce high quality stoolbed rootstock plants for nursery use.
