Budagovski 9, also known as Bud 9, produces trees that are slightly smaller than M9 (NIC® 29).  Bud 9 produces a tree that is approxately 20-30% the size of a standard seedling and require support.  These trees are precocious and produce large fruit.  Bud 9 is resistant to collar rot and moderately resistant to powdery mildew and apple scab.  It is exceptionally winter hardy as well.  Trees grown on Bud 9 are much less likely do die due to fire blight than trees grown on M. 9 rootstock.
