greater rust resistance of the durum wheat. The rank in yield of the 
other three varieties at these two stations was reversed. For the five 
stations where results were obtained the Kubanka ranked first, 
Ghirka second, Rysting-Glyndon third, and Haynes fourth. 
The favorable season of 1913 resulted hi good yields at all stations 
except Highmore. The Kubanka led in yield at Moccasin, Williston, 
and Brookings, the Ghirka at Edgeley and Newell, the Rysting at 
Dickinson, and the Glyndon at Highmore. For all stations the Ku- 
banka ranked first, Ghirka second, Rysting-Glyndon third, and 
Haynes fourth. 
The season of 1914 was favorable at Moccasin and Williston, but 
drought, hail, and rust reduced the yields at the other stations. The 
yields have been computed for certain varieties which were not grown 
at three stations in 1914. The Haynes was discarded at Moccasin 
after 1912 and the Ghirka at Brookings after 1913. The Kubanka 
and Ghirka were unfortunately omitted, through error, from the test 
at Xewell in 1914. The yields at Dickinson were damaged about two- 
thirds by hail. Rust reduced the yields at Edgeley, Brookings, and 
Highmore as much or more than drought. 
The Kubanka produced the best yields at Williston, Edgeley, 
Brookings, and Highmore and equaled the yields of Ghirka and Ryst- 
ing at Moccasin. The yield of Ghirka was relatively less at all sta- 
tions except Moccasin than that usually obtained. For all stations 
the Kubanka ranked first, Rysting-Glyndon second, Ghirka third, 
and Havnes fourth. 
SUMMARY OF YIELDS. 
The averages for the seven years from 1908 to 1914, inclusive, cov- 
ering a period of varying seasonal conditions, show a remarkable uni- 
formity of results for the different varieties at each station. The 
Kubanka durum leads all varieties at ail stations except Dickinson. 
Had the comparison included the results for 1907 at Dickinson the 
Kubanka would have outyielded the other varieties. A selection 
from Kubanka called Kubanka No. 8 (C. I. Xo. 4063) also outyielded 
the other varieties at Dickinson for the 5-year period from 1910 to 
1914, inclusive. 
The Ghirka has ranked second at Moccasin, Williston, Edgeley, and 
Xewell, and tied with Rysting for second rank at Brookings. At 
Dickinson the Ghirka was first and at Highmore fourth. 
The Rysting-Glyndon ranked third at Moccasin, Williston, High- 
more, and Xewell and tied at Brookings for second place. At Dick- 
inson it ranked second and at Edgeley fourth. 
The Haynes gave the lowest yields at Moccasin, Williston, Dick- 
inson, Brookings, and Xewell. It ranked third at Edgeley and 
second at Hio-hraore.
