Narrative

The Chehalem has been tested as Oregon-731 and is a cross between Santiam (Ideal Wild) and Himalaya. The cross was grown at Corvallis, Oregon, and the selection was made in 1939The Chehalem ripens from 5 to 15 days after the Boysen, almost to the beginning of the season for the Evergreen blackberry. It has a bright black color, that makes a very attractive frozen product, and is the characteristic most desired by packers of frozen fruit. The berries are somewhat smaller and longer than Logan and are of high flavor. The drupelets and seeds are small, about the size of the native blackberries, It is firm enough to keep its shape after freezing. The plant is vigorous, but the trailing canes are easily handled, and it propagates very readily by tips of the canes. It is a very productive variety,Tests so far have shown that the Chehalem is adapted to the Willimette Valley of Oregon, particularly the northern part. Its adaptability to other areas has not been definitely determined. It is suggested for trial in areas West of the Cascade mountains in Oregon and Washington where blackberries are grown for freezing.
