Wheat Hardness: Effects of Debranning and Protein Content.

Wheat hardness measurements on pearled wheat showed that the bran has some effect on the magnitude of the hardness index but essentially no effect on the ranking of cultivars within a group covering soft, hard red spring, and durum classes. Results for nine samples of one variety of hard red spring wheat from one location, all having protein contents in the 9.4-15.6% range, showed that hardness decreases with increasing protein for some indices and remains essentially constant for other indices. Results for all indices on debranned wheat showed that protein content had no effect on endosperm hardness.
