Chehalem × Olallie; cross made in 1945; selected in 1948; tested as US-Oregon 928. Tree: trailing; vigorous grower; generally only a few long canes, up to 20 ft long; spines large and numerous; fruiting laterals long and strong, with many fruits; very productive, more so than Boysen, higher yields for a longer period than Boysen; adapted to western Oregon and western Washington. Named after Marion County, in which it was tested extensively. Fruit: medium to large; round in cross diameter, somewhat longer than wide; individual drupelet and seed size medium; skin bright black, not as bright as Chehalem or Evergreen, but more attractive than Boysen; flesh medium firm; quality high with excellent flavor, generally superior to Boysen or Evergreen; excellent for local markets, canning, freezing, pies, ice cream flavoring, jams, jellies; harvest season more favorable than Evergreen, ripening in Boysen season and before Evergreen in Oregon; resembles Himalaya or Chehalem.
