3055, was grown each year, and Kharkof, C. I. No. 1442, was grown 
from 1914 to 1917, inclusive, for comparison. Four of these selections 
are awnless, very similar to Alton (Ghirka Winter) wheat. They, 
however, are more vigorous and have larger kernels than Alton. 
The grain is very similar to that of Turkey and probably equal to 
that variety in quality. 
Selection No. 159 produced the highest average yield, 26.1 bushels 
per acre, which was 1.3 bushels more than the parent strain, C. I. No. 
3055. This selection was one of the highest yielders in the nursery 
experiments, and it also outyielded all varieties and selections in the 
experiments under irrigation. Of the 600 original selections this 
is the only one which has shown a marked increase over the parent 
varieties. 
The awnless strains yielded less than Turkey or Kharkof and most 
of the awned selections. The highest yielding awnless selection, 
C. I. No. 5299, has an average yield of 1.7 bushels per acre less than 
Turkey, but it yielded slightly more than the Turkey variety in 1914. 
The better awnless selections have been fully as hardy and nearly as 
resistant to drought as the Turkey variety. Because of the lower 
yields of the awnless strains none of them was distributed. 
RATE-OF- SEEDING EXPERIMENTS. 
Experiments to determine the best rate to sow Kharkof winter 
wheat were attempted from 1910 to 1918, inclusive. The 1910 crop 
failed to germinate, and the 1912 crop did not emerge until late in 
the spring following the seeding and was plowed up. The 1911 crop 
was killed by spring and summer drought and the 1917 and 1918 
crops were destroyed by a combination of winterkilling and soil 
blowing. Results from the rate-of-seeding experiment were thus 
obtained only during the period from 1913 to 1916, inclusive. Good 
crops were obtained except in 1916, when winterkilling and soil blow- 
ing injured the crop, in addition to severe damage from stem rust. 
The rates of seeding here recorded ranged from 2 to 7 pecks per 
acre. The yields are shown in Table XV.
