Interpretive Summary: 'Black Butte' trailing blackberry (Rubus L. subgenus Rubus) was released as a cultivar by the U.S.D.A.-Agricultural Research Service in cooperation with Oregon State University in 1996. 'Black Butte', tested as ORUS 1129-1, was selected from a cross of ORUS 830-4 (ORUS 2027 x ORUS 1826)x ORUS 728-3 (ORUS 1717 x ORUS 1826). Rubus ursinus is the primary species in the background of 'Black Butte' but R. idaeus and R. armeniacus are distantly present in the pedigree. The outstanding characteristics of 'Black Butte' are its extremely large (9.5-12.0 g/fruit), well formed, and firm fruit, similar yields to 'Marion', early season production, and a plant that is similar to other thorny, trailing blackberry cultivars in habit, vigor, and disease reaction. 'Black Butte' is expected to do well where other trailing cultivars are adapted. 'Black Butte' is introduced as a berry for the fresh market, pick-your-own operations, and homeowners.
