CRUDE-PROTEIN CONTENT 
The quantity of crude protein in the 
wheat and flour is a standard index of 
the quantity of gluten. Determina¬ 
tions in this study were made by the 
method described by Shollenberger, 
to Kota. Twenty-nine hybrid selec¬ 
tions averaged 16.1 per cent crude 
protein in the wheat, while duplicate 
samples of Kota, Marquis, and Hard 
Federation averaged 15.9, 15.7, and 
14.7 per cent, respectively.

Marshall, and Coleman (31) (N.X5.7, 
basis 13.5 per cent moisture) in the 
Research Laboratory of the Grain 
Division of the Bureau of Agricultural 
Economics. The results obtained on 
crude protein in the kernels are shown 
in Table XXVIII. 
The data show evidence of segre¬ 
gation in crude-protein content of the 
kernels. The small numbers involved 
do not permit of any definite conclu¬ 
sion, but in general it appears that 
high crude-protein wheats can be 
obtained from this cross as most of 
the selections are equal or superior 
The results obtained on crude protein 
in the flour are given in Table XXIX. 
The data on crude protein in the 
flour also show evidence of segregation 
and, while the disparity of numbers 
prevents definite conclusions, it ap¬ 
pears probable that in this cross hybrid 
selections can be obtained which exceed 
the parents in the quantity of their 
gluten. Twenty-eight hybrids aver¬ 
aged 15.6 per cent crude protein in the 
flour while duplicate samples of Kota, 
Hard Federation, and Marquis aver¬ 
aged 14.9, 14.6, and 14.3 per cent, 
respectively.
