Narrative

Conference (541168).-A standard for midseason dessert pears in western Europe. Originated at Sawbridgeworth, England, by Thomas Rivers and Sons and introduced in 1894. Leon LeClerc de Laval o.p. Exhibited at the National British Pear Conference in 1885, for which it was later named. Fruit: medium to large size; long pyriform; skin smooth, green, unevenly russeted; flesh pale yellow with pink tinge, tender, melting, very juicy, sweet. Season: October and November; good storage life. Cropping early, regular, heavy; tends to produce misshapen parthenocarpic fruit. Self-fertile, diploid; good pollen. Tree: moderately vigorous; very productive; susceptible to fire blight. Highly rated in Europe, but has not performed as well in Oregon. - Brooks and Olmo Register of Fruit and Nut Varieties
