Objective: 

To evaluate spring wheat varieties and experimental lines for agronomic performance in environments and cropping systems representative of northwestern Montana. 

Results:

Significant differences were observed in heading date, height, lodging, percent stripe rust infection, percent tan spot infection, yield, protein, test weight, and pre-harvest sprout. Heading date averaged 172 days (June 20) and spanned a nine day period ranging from 168 to 177 days. The mean height was 34.1 inches and ranged from 29.1 inches for WB 161 to 46.5 inches for Fortuna. Lodging averaged 0.9% with a range from 0.0% to 12.7 percent. Grain yield averaged 82.5 bu/A and ranged from 61.2 bu/A for MT 1517 to 107.5 bu/A for HRS 3504. Despite having applied a fungicide, stripe rust did occur in all varieties. Average percent infection was 33.4% and ranged from 2.0% for WB 161 to 63.3% for MT 1510. Protein averaged 14.80% and ranged from 12.53% for WB 162 to 16.27% for SY Igmar. Test weight averaged 61.0 lb/bu and ranged from 59.2 for MT 1510 and MT 1565 to 62.7% for SY Tyra. Pre-harvest sprout averaged 64.7 and ranged from 11.4 for LCS Prime to 191.8 for WB 161.

Summary:

Overall, average yields were less in 2016 (82.5 bu/A) compared to the previous year (111.2 bu/A), which is partially attributed to the combined effects of stripe rust and tan spot.  HRS 3504 was the highest yielding variety, but LCS Prime, Egan, LCS Pro, SY Valda, WB Gunnison, Reeder and Vida were statistically equivalent.
