Origin: in Corvallis, Ore., by George F. Waldo, U.S. Dept. of Agriculture and the Oregon Agr. Expt. Sta. Introd. in 1950. Black Logan × Young; selected in 1938; tested as Oregon 609. Tree: very productive; canes vigorous, thorny, trailing; adaptable to California, western Oregon, and Gulf Coast conditions; winter-chilling requirements shorter than for Boysen, thus recommended for southern California; grown extensively near Watsonville, Calif.; resistant to verticillium wilt and powdery mildew; very susceptible to systemic orange rust when grown in a humid climate. Fruit: large; slightly longer and more slender than Boysen; skin shiny black, attractive; flesh firm; flavor good, but peak quality reached only at full maturity; resembles Mammoth. Excellent for processing.
