This is a non-dwarfing rootstock from Russia and produces a free-standing tree that is 100% standard size. Trees are slow coming into bearing and moderately productive, and trees may lean slightly in some situations. Although some nurseries advertise Antonovka 313 to be very cold hardy, it is usually considered moderately cold hardy and may be susceptible to late-winter cold. It is adapted to a wide range of soil conditions, and is reportedly resistant to crown rot and moderately susceptible to fire blight. Trees may produce some root suckers, but few burrknots. In a California study where trees were grown in containers with soil artificially infested with P. cactorum, Ant. 313 developed severe crown rot symptoms. In the NC-140 1984 rootstock trial, Antonovka 313 had good tree survival across 30 North American locations, and yield and yield efficiency were slightly higher than trees on seedling rootstock.
