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 than variability among varieties. 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, the wheat protein concentration is reported 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 about 95% of this year’s trials, indicating a tendency for above-average wheat protein concentration. Iba, on the other hand, showed a negative deviation from location mean in 85% of the trials, indicating a tendency for lower-than-average wheat protein concentration. Adequate and timely nitrogen fertility as recommended by a recent soil test or sensor-based nitrogen management program can help ensure 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 used as a barometer for protein quality (i.e., dough strength and functionality). Although, there are few exceptions to this, with Doublestop CL Plus being one example. Iba is also a prime example of how protein data can sometimes be misused, 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-gram subsamples of wheat grain were collected at harvest from four field replicates of all entries for each OSU 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 2019-2020 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 determinator (model DA 7200, Perten Instruments, Sweden).
