Glyndon is shown to be considerably inferior to Marquis in volume of 
loaf, the principal bread-making factor. It is inferior to Marquis in 
yield, and should be displaced by that variety. 
Table 13. — Summary of milling and baking data on 36 samples of Glyndon 
and 36 comparable samples of Marquis grown during the seven years from 
1915 to 1921, inclusive.

Haynes Bluestem. — The Haynes Bluestem variety, known also as 
Bluestem. Marvel Bluestem, and Minnesota No. 169, was first de- 
veloped through selection by L. H. Haynes, of Fargo, N. Dak., 
about 1895. Bluestem wheat was grown in the Dakotas, however, 
before Mr. Haynes distributed his strain. The variety was further 
selected by the Minnesota Agricultural Experiment Station, which 
distributed a pure-line selection known as Minnesota 169, in the 
late nineties. The name Haynes Bluestem is now commonly used 
for the several strains that have been developed and grown. It 
is an awnless, pubescent (velvety), white-glumed wheat, that ma- 
tures late and is frequently injured by rust and drought. 
In all, 128 samples of Haynes Bluestem wheat have been milled. 
Fifty-four of these can be directly compared with samples of 
Marquis grown under the same conditions. Many commercial 
samples of Bluestem wheat were obtained from farmers, elevators, 
and milling companies in the Dakotas and Montana. The samples 
that can be compared with Marquis were obtained from the experi- 
ment stations in North Dakota, South Dakota, Minnesota, Montana, 
Wyoming. Nebraska, and Texas during the seven years from 1915 to 
1921, inclusive. A summary of the comparable samples and those of 
Marquis are shown in Table 14. 
The data show Haynes Bluestem to have a lighter test weight 
per bushel than the samples of Marquis grown under similar condi- 
tions. This is in part due to its great susceptibility to stem rust. 
In crude protein the Haynes Blustem slightly exceeds Marquis, 
as it does in water absorption of flour. In yield of straight flour 
and in volume, texture, and color of loaf it is inferior to Marquis. 
Flour from Haynes Bluestem has averaged higher in ash than that 
from Marquis. Haynes Bluestem has produced lower yields than 
most other varieties of hard red spring wheat, due largely to 
its late maturity. Considering all these facts it would be advisable 
to discontinue Haynes Bluestem from cultivation,
