OHF (OLD HOME X FARMINGDALE)
Clone 19-89 Pear rootstock selected from micropropagated plants of OHxF by Fitotechniki in 1989 (original plant material obtained in 1986 from Prof. James Cummins, Cornell University, New York). Needs careful management in the nursery (irrigation and fertigation) to facilitate plant growth; rootstocks should ideally be planted in the nursery before May to ensure an optimal size for grafting in summer. No suckering. Resistant to Fire Blight (Erwinia amylovora), nematodes and Phytopthora Cactorum. Tolerant to drought, heavy and calcareous soils and to low temperatures; suitable for replanting. Plants grafted on this rootstock develop a deep root system and good anchorage with no need for support. All pear varieties show perfect grafting compatibility, 30-35% lower vigour than plants grafted on seedlings and similar vigour to those grafted on quince rootstock ‘BA29’. Suitable for medium and low vigour pear varieties (William, Abbé Fétel, Etrusca, Highland, etc. and Asian pear varieties). Suitable rootstock for dry and calcareous soils and for medium and low density pear orchards (about 2000-2500 trees/ha).
