Formerly Bud 62-396.
It is a release from the Michurinsk University of Agriculture (Russia) breeding program, which is trying to select for improved winter hardiness.
A 10-year trial in Pennsylvania with Golden Delicious as the scion cultivar showed that trees on this rootstock were similar in size to trees on G.935 and M.9 T337 (15 percent smaller).
Main scaffold branch angle was close to 90 degrees. Production efficiency and total yield were slightly better than trees on M.9 T337.
