The P 1 rootstock belongs to the Polish breeding series of rootstocks for apple trees. In terms of vigor, it is classified as semi-dwarf, constituting approximately 53% of the vigor of trees on Antonovka common seedling rootstocks, which makes its characteristics close to the M.26 rootstock.
Trees grafted onto this rootstock are characterized by a relatively early entry into the fruiting phase. P 1 is propagated vegetatively using layers and is used in intensive horticulture to shape the structure and height of fruit trees.
