Oklahoma, Illinois, and Missouri. Considerable decreases in acreage 
and in relative importance occurred in Kansas and Oklahoma, 
largely on account of an increase in acreage of Blackhull. A slight 
increase in relative importance in Illinois probably is due to its being 
grown more largely in the central section of the State, where a soft

for this class of wheat. Harvest Queen is one of the most hardy 
soft red winter wheats and has an unusually stiff straw. It is very

to an awnless wheat with glabrous, white glumes, and in this summary
