Narrative
Fire blight resistant rootstock. The Southern Oregon Experiment Station made a concerted attempt to find fire blight resistant root and framework stocks from 1923 and 1931. Over 10,000 French P. communis seedlings were grown and repeatedly inoculated with the blight organism, and after 5-6 years only ten trees survived. These seedlings were capable of transmitting blight resistance to a high percentage of their progeny, particularly when cross pollinated with other blight resistant pears. The best of the resistant seedlings were W-1, W-2, P-18, P-30, P-61, P-70 and P-87 (F. Reimer. 1950. Oregon Agricultural Experiment Station Bulletin 485). -- H. Hartman, 1957.
