Narrative

OHxF 267 (PI 541400). A semi-vigorous blight resistant rootstock. The OHxF Series (Brooks Selections) originated near Forest Grove, Oregon, by Lyle A. Brooks from seed obtained at Agriculture Canada Research Station., Surnmerland, B.C. Old Home x Farmingdale. From several thousand seedlings, Brooks, M.N. Westwood, and P. Lombard selected and evaluated in the orchard less than 500 candidates. Thirteen have been introduced commercially; all are resistant to fire blight, pear decline, and woolly pear aphids; they produce no or few suckers; propagation (with difficulty) is by hardwood cuttings. The Brooks Selections are compatible with Pyrus communis varieties and appear to be compatible with Asian pear varieties. - Brooks and Olmo Register of Fruit and Nut Varieties
