^[1]^{Yield values corrected to 12% moisture content. Bolded values indicate highest LSD grouping.}

^[2]^{Protein corrected to 14% moisture content, the correction factor used in analytical standards.Checks excluded from protein LSD groups due to known high protein contents.}

^[3]^{For differences between varieties that are equal to or greater than the LSD value, the chance that the difference is significant is 90%.}

^[4]^{Mean performance of all plots in the trial.}

^[5]^{Coefficient of Variation (CV) indicates the quality of a trial, and lower than 15 indicates a high-quality trial. For CV>15, there was higher than expected variability in the field or the data and the results should be used with caution.}

Site Information	Details
Collaborator:	Tom, Chris, and Luke Cullan; Cullan Farm Seeds
Planting Date:	10/14/2025
Seeding Rate:	1.75 million s/a
Harvest Date:	7/21/2026
Soil Type:	Alliance loam
GPS:	42.281254, -103.014672
Planting Info:	Drilled 1.5" into tilled dry bean stubble with great soil moisture
Notes on Trial:	Had some rain just before planting and good fall growth. Significant irrigation took place throughout the season due to warmer than usual winter. Due to later planting date and irrigation, early heading was not observed, mitigating freeze damage exhibited in dryland fields in area. Telluride (denoted with an asterisk) is a hard white wheat, otherwise all other varieties are HRWW.
