RUST RESISTANCE. 
Table 4 shows the annual and average percentage of stem-rust 
infection recorded on the Kubanka selections at Fargo, N. Dak., 
during five years in the nursery and three years in plats; at Dick- 
inson, N. Dak., during three years in the nursery and in 1920 and 
1922 in plats; and at Edgeley, N. Dak., in 1922 in plats. The 
columns showing average rust percentages indicate that Nodak 
(Kubanka No. 98) and Kubanka No. 99 are two of the most rust- 
resistant selections. These two selections ranked high in yield at 
Dickinson and at Fargo, as previously stated. Kubanka Nos. 94 
and 117 are also quite rust resistant. The latter produced a high 
yield at Edgeley in 1922, while both ranked comparatively high in 
the 2-year average yield in plats at Fargo. Kubanka Nos. 58, 97, 
and 132 are shown to be very resistant to rust at Dickinson, but 
were not grown at Fargo. No. 58, which is a red durum, yielded 
well at Dickinson.
