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 winter wheat registration/recommendation trial, consisting of 16 advanced lines, and a winter wheat screening trial, consisting of 28 lines, was established on the 12th day of September, 2003. . These trials are part of the Maritime testing system for small grains. Dry matter yield values from the winter wheat registration/recommendation trial ranged from 2.80 tons/hectare to 4.07 tons/hectare. Lowest and highest yielding lines were AC Winsloe and 1995-69-5, respectively. Leaf diseases were detected among the lines. Fusarium toxin (DON) levels ranged from 0.0 ppm to 1.0 ppm. Toxin levels below 1 ppm are considered acceptable. Dry matter yield values from the winter wheat screening test ranged from 2.57 tons/hectar to 4.33 tons/hectare. Lowest and highest yielding lines were MS 1 and 9768-3, 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.
