Budagovsky 9 is a dwarfing rootstock resulting from a cross between M.8 x ‘Red Standard’ (Krasnij Standard) from Russia. B9 has been widely tested and is used commercially throughout the U.S. It is slightly more dwarfing than M9 and is slightly more productive.
Other traits of note: Very early precocity; very winter hardy; little suckering; requires support; adapted to well drained soil; very resistant to crown rot; more fireblight resistant than M9.
*Plant growth is always influenced by climate, nutrition, water availability, scion vigour, etc, so height figures are always only a guide.
