| OHxF x 333 PEAR ROOTSTOCK (Pyrus communis) |
| Semi-dwarfing rootstock for European Pear, developed in OR in 1940s. OHF stands for Old Home x Farmington, which were crossed to achieve complete fireblight resistance. It is 1/2 to 2/3 standard size. Its resistance to fireblight, collar rot, woolly pear aphids and pear decline make this a very healthy stock. Precocious, well-anchored. Trees are very productive. Some reports that fruit size is reduced. All the OHxF x333 are propagated by cuttings or in tissue culture, with considerable difficulty, as all are reluctant rooters. |
