Abstract: The New Brunswick Soil and Crop Improvement Association with funding from the Strategic Partnership Development Program in co-operation with the New Brunswick Department of Agriculture, Fisheries and Aquaculture conducted small grain cultivar evaluation trials in Hartland, New Brunswick in 2004. A six-row barley registration/recommendation trial, consisting of 20 advanced lines, and a six-row barley screening trial, consisting of 30 lines, was established on the 10th day of May, 2004. These trials are part of the Maritime testing system for small grains. Dry matter yield values from the six-row barley registration/recommendation trial ranged from 3.9 tons/hectare to 4.63 tons/hectare. Lowest and highest yielding lines were OB5275-1 and CFO281AA40, respectively. Leaf diseases were detected among the lines. Fusarium toxin (DON) levels ranged from 1.8 ppm to 4.2 ppm. Toxin levels under 1 ppm are considered to be acceptable. Net Blotch values ranged from 0.1 to 1.2. Dry matter yield values from the six-row barley screening test ranged from 3.37 tons/hectare to 4.47 tons/hectare. Lowest and highest yielding lines were OB4993-9 and OB5297-3, respectively. Data from these trials are used to recommend lines for registration and to recommend cultivars for commercial production in New Brunswick. No varieties were selected for recommendation and/or registration.
