1 For 1907 and 1908, Kubanka (C. I. No. 1440); for 1909 to 1913, Kubanka No. 8 (C. I. No. 4063), a pure- 
line selection from C. I. No. 1440 made at Dickinson, N. Dak. 
2 For 1907 to 1910, Arnautka (C. I. No. 1494); for 1913, Arnautka6P1(C. I. No. 4046), a pure-line selection 
from C. I. No. 1494 made at Akron, Cclo. 
3 Estimated from yield of Kukanka (C. I. No. 1440). 
4 For 1907 to 1909, Haynes Bluestem (C. I. No. 3020); for 1911 and 1913, Haynes Bluestem (C. I. No. 2870). 
These two lots of seed were from the sam2 origixal source the Minnesota Agricultural Experiment Station. 
5 Estimated from yield of Crossbred (C. I. No. 3314) 
Of all the varieties tested, a few of outstanding merit should be 
more widely known. With a full knowledge of each of the leading 
varieties, the individual farmer can decide which he prefers to grow. 
He can then, by careful cleaning and grading of the seed, maintain 
the quality of his crop and keep it above the average. | 
THE DURUM GROUP. 
The Kubanka and Arnautka have proved to be the best of more 
than 20 varieties of durum wheat tested at Dickinson. These 
varieties are very similar in appearance. Both have long yellowish 
beards, smooth yellow chaff, and very hard, clear amber grain.t 
Kubanka—The Kubanka (C. I. No. 1440) is considered the best 
durum wheat for western North Dakota. The plants are taller than 
the spring common wheats. The heads are short and broad (fig. 4) 
and the grains large. This wheat was introduced into the United 
States from Russia in 1899 by Mr. M. A. Carleton, Cerealist of the 
United States Department of Agriculture. In the tests at Dickinson 
it has been one of the leading varieties nearly every year. Its 
superiority over other durum wheats was early recognized, and a 
number of pure-line selections were made in 1906 by Mr. L. R. 
Waldron. One of these, Kubanka No. 8 (C. I. No. 4063), has proved
