the manufacture of macaroni and other alimentary pastes. Kubanka, 
in the durum-wheat region, has been found to be more resistant to 
stem rust than Arnautka, Peliss, and: Kahla, being about as resistant 
as Mindum. : 
COMPARATIVE YIELDS. 
In most of the durum-wheat region Kubanka considerably out- 
yields all varieties of hard red sprig wheat. It also usually out- 
yields Arnautka, Kahla, Mindum, and Peliss durum wheats in the 
Dakotas, the principal area of durum wheat production in the United 
States (fig. 1). It is usually slightly exceeded in yield by Monad, 
Acme, and Pentad, particularly in years when severe rust epidemics 
occur. 
Table 1 shows the annual and average yields obtained from Ku- 
banka (C. I. No. 1440) and a selection from it, Kubanka No. 8 (C. I. 
No. 4063), grown at the Dickinson substation, Dickinson, N. Dak., 
and from Kubanka (C. I. No. 1440) at the North Dakota Agricultural 
Experiment Station at Fargo, in comparison with the leading varieties 
of durum and common wheat. 
TABLE 1.— Yields of Kubanka durum wheat and of other leading varieties of durum and 
common wheats grown at Fargo, N. Dak., and at Dickinson, N. Dak., from 1907 to 
1922, wnclusive. 
(The varietal experiments at Fargo were affected by excessive rains and weeds in 1905, 1909, and 1912, 
and yields for these years were not recorded. These varieties were not grown at Fargo in 1915. The 
crop of 1912 at Dickinson was destroyed by hail. These years are not considered in the respective 
averages.]
