‘Onyx’ is a new trailing blackberry (Rubus subg. Rubus Watson) cultivar from the U.S. Department of Agriculture–Agricultural Research Service (USDA-ARS) breeding program in Corvallis, OR, released in cooperation with the Oregon Agricultural Experiment Station. ‘Onyx’ is a vigorous, somewhat erect, thorny, trailing blackberry that produces moderate yields of uniform, firm, and sweet high-quality fruit with excellent flavor that are suited for the local and wholesale fresh market (Figs. 1 and 2). ‘Onyx’ is being released primarily as a result of its outstanding fresh fruit quality in the late season. An application for a U.S. plant patent has been submitted.
