BULLETIN 1183, U. S. DEPARTMENT OF AGRICULTURE. 
14,000,000 acres of this class of wheat are grown annually in the 
United States, comprising nearly one-fourth of the total wheat 
acreage. In 1919, as shown in Table 8, the acreage exceeded 
16,000,000 acres. 
Although 24 distinct varieties of hard red spring wheat are grown, 
about two-thirds of the acreage of this class consists of the one 
variety, Marquis. This variety is taken as the standard for com- 
paring all other varieties of hard red spring wheat. Milling and 
baking experiments have been made with nearly all of the 24 varie- 
ties, but tests of 5 or more samples have been made with only 17 of 
these. A summary of the results obtained from all samples of these 
IT varieties of hard red spring wheat are shown in Table 9.

1 This column contains the maximum number of samples used for each variety. In some instances, 
particularly for the factors of loaf color and ash, the results given represent the average of a fewer number 
of samples for the reason that complete data on all the samples were not available. The number of samples 
used for the various factors is given in Figures No. 12 to 23, inclusive. 
2 Average of all hard red spring wheat samples on which tests were made, including the varietal samples 
shown above.
