greater rust resistance of the durum wheat. The rank m 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-Gljmdon third, and Haynes fourth. 



The favorable season of 1913 resulted in 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 Gljnidon 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 WilHston, but 

 drought, hail, and rust reduced the yields at the other stations. The 

 yields have been computed for certaui 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 Newell 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 Kyst- 

 ing at Moccasm. 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 Haynes fourth. 



SUMMARY OF YIELDS. 



The averages for the seven years from 1908 to 1914, inclusive, cov- 

 ering a period of varymg seasonal conditions, show a remarkable uni- 

 formity of results for the different varieties at each station. The 

 Kubanka durum leads all varieties at all 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. No. 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 

 Newell, 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, WiUiston, High- 

 more, and Newell 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, WiUiston, Dick- 

 inson, Brookings, and Newell. It ranked third at Edgeley and 

 second at Highmore.
