Protein Concentration of Winter Wheat Varieties in Oklahoma - 2022-2023
General Information
Protein is just one of many attributes that determines end-use quality and marketability of winter wheat. In fact, some millers and bakers would argue that functionality of wheat protein is more important than the quantity of protein. While varietal differences exist, variability in protein among environments is generally much larger. Factors such as nitrogen (N) fertilization and drought stress, for example, can sharply impact final wheat protein concentration.
To reflect these management and environmental impacts on wheat protein concentration, data are reported by variety and location in Table 1. In Table 2, it shows the wheat protein concentration by variety as a deviation from the location mean.This allows for easier comparison of wheat protein among varieties across locations. Doublestop CL Plus and Green Hammer, for example, showed positive deviation from the location mean in all of this year’s trials where it was planted, indicating a tendency for above-average wheat protein concentration. Adequate and timely N fertility as recommended by a recent soil test or sensor-based N management program can help ensure that varieties with lower than average protein produce wheat or flour protein within the acceptable range for the end-users.
However, protein quantity should not be considered a barometer for protein quality (i.e., dough strength and functionality), though high protein quantity and quality can occur in the same variety. Doublestop CL Plus is one example. Iba is a prime example of how protein data can sometimes be misleading, as the functionality of the protein in Iba is above average, which can offset lower absolute protein concentration. More information on end-use quality is available in Current Report 2165, Wheat and Flour Quality for Varieties Tested in the 2016 OSU Variety Performance Tests.
Procedures
Approximately 600 g subsamples of wheat grain were collected at harvest from four field replicates of all entries for each Oklahoma State University Wheat Variety Performance Test. Each test was properly fertilized and managed according to OSU Extension recommendations. Additional information on test locations and management practices is available in Current Report 2143, 2022-2023 Oklahoma Small Grains Variety Performance Tests online at www.wheat.okstate.edu. Samples were analyzed nondestructively immediately after harvest for wheat protein concentration on a 12% moisture basis, using a Diode Array Near Infrared (NIR) moisture and protein instrument (model DA 7200, Perten Instruments, Sweden). The expected wheat protein concentration for hard red winter wheat in the Southern Great Plains resides in the 10% to 15% range. Grain samples with extremely high protein concentration (e.g., 18-21%) were also analyzed using the LECO and Elemental CN combustion method and results were confirmed. Overapplication of N in a low-yielding drought year could inflate grain protein concentration values.
Data Interpretation
At the bottom of Table 1, the mean and least significant difference (LSD) values are reported.The LSD is a test statistic that aids in determining whether there is a true difference in protein. In this report, one can be 95% confident that the difference between two varieties is real if the difference is greater than the LSD value. Data that is not statistically different is indicated by “NS.” For example, if the LSD value is 1% in a trial where Variety A had 13% protein and Variety B had 10% protein, then Variety A would be considered to have a statistically higher protein. However, if Variety C had 12% protein, then Variety A and Variety C would be considered to have a similar protein. In that same example trial, there is a 5% chance that the 1% protein difference between Variety A and Variety B does not truly exist, but random chance caused the difference. These chance factors may include differences in fertility, moisture availability and diseases. To aid in visualizing the varieties with the highest protein, values highlighted in gray do not differ statistically from the highest value within a column.

Notes: Protein was adjusted to 12% moisture content. Shaded values are not statistically different from the highest value within a column. Due to the presence of weed seeds in the grain samples of the El Reno grain-only trial, grain protein concentration was not measured. Double-dashes "--" = data not available.
