1 Title: 2011 Off-Station Spring Wheat evaluations in the Western Triangle Area Principal Investigators: John Miller, Western Triangle Ag. Research Center, Conrad, MT. Dave Wichman, Central Ag. Research Center, Moccasin, MT, and Luther Talbert and Susan Lanning, PSPP, Bozeman. Objectives: Evaluate spring Wheat varieties and promising new lines in the Western Triangle area. Results: Results are tabulated in Table 1 for the Cut Bank location and Table 2 is five year averages for selected varieties at the Cut Bank location. Table 3 is for the location north of Devon. Tables 4 and 5 are for the Knees location, with Table 5 being five year averages for the Knees location. Table 6 is irrigated spring wheat with Table 7 being the long term data for the irrigated spring wheat nursery. Table 8 is of the soil test values for the off station plots. The Choteau location was lost due to drowning. Top yielding varieties at Cut Bank were Volt, Choteau, and Kelby with protein averaging 13.8% across all varieties. Volt, Fortuna, and WB Gunnison were the high yielding varieties at Devon while averaging 14.0% protein across all varieties. The Knees high yielders were Duclair, Choteau, and IMICHT79 with 13.9% protein across all varieties. The top yielders in the irrigated trial were Duclair, WB Gunnison, and SY Tyra, with protein averaging 12.8 percent. Heading date for the irrigated nursery was about 10 days later than usual. Summary: Yields ranged from 25 to 63 bu/acre at Cut Bank, 26 to 43 bu/acre north of Devon, and 21 to 45 bu/a at the Knees. Yields in the irrigated trial ranged from 55 to 90 bu/a. No long term data are reported for the location north of Devon as this was the second year for variety trial plots at this location. Rust was not sprayed at the Cut Bank, Devon, and WTARC irrigated locations. Rust was sprayed for by the farmers at the Knees and Pendroy locations as the crop surrounding the plots were winter wheat infested with rust. Some varieties at Cut Bank and Devon were highly affected by the rust. Test weights were lower than might be expected at Cut Bank and Devon. Funding Summary: Office of Special Projects will provide expenditure information. No other grants support this project. MWBC FY2013 Grant Submission Plans: A similar project will be proposed for FY 2013.
