Interpretive Summary: One of the primary objectives of the USDA-ARS in Oregon is the development of high quality blackberry cultivars for the commercial industry. The main goal is to develop thornless processing cultivars that can be machine harvested. These cultivars must have fruit quality similar to or better than the current processing standard 'Marion', which is often marketed as "marionberry". 'Nightfall' is being released as a thornless blackberrry for processing. 'Nightfall' is outstanding because it compares favorably to 'Marion' for its plant, yield, and fruit characteristics in the field and it produces a good quality processed product. 'Nightfall' is recommended for trial in areas where trailing blackberries can be successfully grown.

Technical Abstract: The U.S. Department of Agriculture-Agricultural Research Service, the Oregon Agricultural Experiment Station and the Washington Agricultural Research Center announce the release of a thornless (botanically 'spineless') blackberry for the processing market. 'Nightfall' was selected in Corvallis, Oregon in 1996 from a cross of 'Marion' and 'Waldo' and tested as ORUS 1486-2. 'Marion' is the industry standard for the processed fruit market, but it has thorny canes. 'Waldo' was the first named thornless trailing blackberry cultivar and has had some acceptance as a commercial cultivar; its fruit flavor is good, but it is very different from the standard 'Marion'. 'Nightfall' is outstanding because it compares favorably to 'Marion' for its plant, yield, and fruit characteristics in the field, and it produces a good quality processed product. 'Nightfall' is recommended for trial in areas where trailing blackberries can be successfully grown. As with 'Marion', NIGHTFALL is not suited to the wholesale fresh market as it is too soft.
