Semi-dwarf rootstock, about 85-90% of standard. Sometimes referred to as a “semi-standard” or even a standard. Space trees 20-25' apart.
More productive and precocious (fruits at a young age) than trees on Antonovka. Very winter hardy and soil adaptable. Generally not used in commercial orchards due to its large size.
