SPRING WHEAT ON THE NORTHERN GREAT PLAINS. \) 
obtained from Mr. T. N. Oium, of Lisbon, N. Dak. A pure-line selection (C. I. 
No. 4064) from this mass variety has been grown at most agricultural experiment 
stations and distributed somewhat. A commercial lot of seed (C. I. No. 1493), origi- 
nally called "Wild Goose," obtained in North Dakota in 1901, has been grown also. 
This is identical with Arnautka. The Arnautka variety differs from the Kubanka 
j^, chiefly in having a longer, narrower, laxer, and more tapering and more nodding 
spike. The variety is known in some sections under the names of local growers. 
One such strain, Pierson, was distributed by George H. Pierson, of Claremont, 
S. Dak., in 1914, and is recorded in this bulletin under that name. 
Mindum. — The Mindum variety is the result of a selection made at the Minnesota 
Agricultural Experiment Station from a variety called Hedgerow, which was probably 
only a local name for Arnautka. This variety is very similar to the Arnautka, but 
is more resistant to stem rust. 
Monad. — The Monad variety was obtained from Russia by Prof. H. L. Bolley, of 
the North Dakota Agricultural Experiment Station, in 1903, while making a study 
of the flax industry of Europe for the United States Department of Agriculture. 
The variety was distributed by Prof. Bolley as D-l (Durum No. 1), but was later 
named Monad after it was found to be a high-yielding variety and resistant to stem 
rust in experiments at the Dickinson Substation, Dickinson, N. Dak. It is very 
similar to the Acme variety except that it has a somewhat stronger straw. 
Marouani. — The Marouani variety was introduced by the Department of Agriculture 
from Algeria. It differs from the Arnautka and Kubanka wheats in being earlier, 
taller, and having longer beaks on the outer glumes. 
Buford. — The Buford variety is the result of a pure-line selection made by Mr. 
F. R. Babcock in cooperative experiments at the Williston Substation, Williston, 
N. Dak., in 1909, from a variety known as Taganrog (C. I. No. 1570). The spikes 
of this variety are about intermediate in length and density between those of the 
Kubanka and Arnautka varieties. 
THE RED DURUM GROUP. 
Several varieties of durum wheat have red kernels, while most 
white or amber kerneled varieties of durum wheat contain slight 
mixtures of red kernels. Some selections of red-kerneled strains 
have been made and increased. Very few of these, however, have 
been grown in the experiments covered by this bulletin, and only 
one red-kerneled variety (D-5) is commercially grown. As this 
variety is not named, the group is here designated by the name of 
the subclass, Red Durum, in which the gram of this variety is graded 
under the United States official grain standards. 
D-5 {Durum No. 5). — The D-5 variety was obtained from Russia by Prof. H. L. 
Bolley. This wheat was distributed by Prof. Bolley in 1911, and because of its rust 
resistance it has gained popularity and is now quite widely grown in the durum- 
wheat section. On the farms this wheat is often wrongly called "D-Fife" and also 
is known as Ladd Durum and Bed Durum. The kernels of the D-5 variety are red, 
midsized, blunt at the brush end, and very tapering at the germ end. The glumes 
are white rather than yellowish, as in the varieties of the Kubanka group. 
THE PELISS GROUP. 
The Peliss group of durum wheat is distinguisned from the Kubanka 
group by black awns and very large kernels. 
Peliss. — The Peliss variety was introduced by the Department of Agriculture from 
Oran, Algeria, where it was developed by a man named Pelissier. It was first called
