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 two-row barley registration/recommendation trial, consisting of 15 advanced lines, and a two-row barley screening trial, consisting of 30 lines, was established on the 10^th day of May, 2004. These trials are part of the Maritime testing system for small grains. Dry matter yield values from the two-row barley registration/recommendation trial ranged from 2.87 tons/hectare to 4.27 tons/hectare. Lowest and highest yielding lines were CDC Copeland and CH9622-7, respectively. Leaf diseases were detected among the lines. Fusarium toxin (DON) levels ranged from 0.1 ppm to 1.0 ppm. Toxin levels under 1 ppm are considered to be acceptable. Net Blotch values ranged from 0.5 to 3.7. Dry matter yield values from the two-row barley screening test ranged from 2.60 tons/hectare to 4.20 tons/hectare. Lowest and highest (2) yielding lines were CH9702n-18 and Island & BM9764-115, 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.
