OHxF 97 Pear Rootstock (Spring 2025)

A full-vigor pear rootstock that is resistant to fireblight, precocious, and productive. Also known as Old Home x Farmingdale 97.

OHxF 97 is an outstanding full vigor clonal rootstock that produces pear trees that are 100% of the size of a Bartlett seedling. This rootstock is cold hardy to zone 4 and more precocious and productive than seedling stock. OHxF 97 is fireblight resistant and is not susceptible to pear decline. It is superior to Betulaefolia for Asian pears, and it does not produce spines on liners or suckers.

OHxF 97 is compatible with all pear varieties.

The OHxF series of rootstocks originated from crosses made more than 75 years ago by Prof. F. E. Reimer at Oregon State University. Reimer was primarily seeking rootstocks that would be fireblight resistant; both parents, Old Home and Farmingdale are highly resistant. Reimer's work was continued by nurseryman Lyle Brooks and by researchers at Oregon State. All the OHxF Series are propagated by cuttings or in tissue culture–with considerable difficulty, as all are reluctant rooters.
