The variety belongs to a series of rootstocks intended exclusively for grafting citrus, such as oranges and mandarins. It is not a fruit-bearing variety and is used to increase productivity and improve the fruit quality of the scion part.
Plants on this rootstock are classified as semi-dwarf, which allows for a 25–50% reduction in the height of grafted trees compared to standard rootstocks. The rootstock forms a strong root system, ensuring reliable anchorage of the tree in the soil.
Breeding of the series is aimed at ensuring high resistance to citrus tristeza virus, Phytophthora, and citrus nematode. The rootstock also possesses high tolerance to calcareous soils, salinity, and waterlogging.
