Results:

This report contains both single-year and long-term data summaries limited to the most recent ten years. It should be noted that 2023 data tables in this report represent varietal performance for a single crop year at a single location only, therefore cannot be considered representative of performance expected when differing conditions due to location, year and management are imposed. By itself, 2023 data shall not constitute in any form a recommendation for or against any variety or breeding line included.

Winter wheat seed yields at Havre averaged just 34 bu/ac (Table 1). Montana State University breeding line ‘MTV2164’ was the top yielding entry producing just under 43 bu/ac, with ‘MS Maverick’, ‘MS Sundown’, ‘StandClear CLP’ and seven other breeding lines producing yields statically equal to that of MTV2164. Test weights of all winter wheat entries for this site averaged just under 57 lb/bu. Wheat stem sawfly cutting in the winter wheat trial at Havre minimal, averaging 10 percent cut and lodged stems. Yield, test weight, protein, heading date, maturity date, plant height and sawfly cutting data for the 2023 Intrastate Yield dryland winter wheat trial are summarized in Table 1.

Comparable averages are calculated using a standard check variety when not all entries are present in a specific trial for all years. Variety means are adjusted by multiplying the actual check mean by the ratio of the individual variety mean compared to the check mean for the same years as tested. All varieties are then directly comparable to each other when in the same nursery. A minimum of three years of data is necessary to be included in the comparable average calculation. Ten-year comparable averages (2014-2023) for winter wheat seed yield and test weight for the Intrastate Yield trial are summarized in Table 2, while ten-year comparable averages for protein content and wheat stem sawfly cutting are summarized in Table 3. Based on the comparable average calculations, ‘Bobcat’, is the highest yielding entry at Havre over time in conjunction with having the least amount of cutting by wheat stem sawfly.

Check variety is Northern.                            
1/ See MCES Bulletin 1098 or the Plant Sciences & Plant Pathology website at http://plantsciences.montana.edu/ for evaluation of other important variety performance characteristics to include protein, quality, disease resistance, etc. before making cultivar selecton decisions.
2/ P = Private Variety, + = Protected Variety, ++ = PVP Title 5 Pending, HW = Hard White Wheat.        
3/ Only the most recent 5 years shown, but summary calculations include all years noted.         
4/ Percent of Northern protein or sawfly rating for the same data years as those in which a given entry was tested.
5/ 10-Yr Comparable Average = (x/y) * z where x = average protein or sawfly rating of a given entry for years tested, y = average protein or sawfly rating for Northern for the same years, and z = 10-Yr average protein or sawfly rating for the check variety Northern.
