THE HARD RED WINTER WHEATS. 9 
The commercial class of wheat known as Hard Red Winter, which 
includes all the varieties of hard red winter common wheats, is grown 
principally in the central Great Plains area, where hot summers and 
rather severe dry winters prevail. The States of Kansas, Nebraska, 
and Oklahoma lead in its production. More than 18,000,000 acres 
of this class of wheat are grown annually in the United States and 
comprise nearly one-third of the total wheat acreage. In 1919, as 
shown in Table 40, the acreage was almost 21,000,000 acres. In Fig- 
ure 6 is shown the distribution of hard red winter wheat in 1919. 
Twelve varieties of hard red winter wheat are grown commercially 
in the United States, but these are known by about 40 different 
names. Several of the varieties are very similar in appearance.

Several additional varieties of hard red winter wheat which are not 
yet commercially grown are grown in experiments. A summary of 
the milling and baking results obtained from the principal commer- 
cial varieties and certain strains grown only in experiments are 
shown in Table 41. The States from which the samples were 
obtained are shown in Table 42.
