SPRING WHEAT ON THE NORTHERN GREAT PLAINS: . 47 
(6) Few new varieties have in any way compared favorably with 
Marquis wheat. The early-maturing varieties Prelude and Pioneer 
escape summer drought in some seasons and are nearly equal to 
Marquis wheat in milling and baking value. In a limited number of 
experiments the Kitchener, Ruby, and Kota varieties show promise 
of being superior to the Marquis. 
(7) Of the two widely grown commercial varieties of durum wheat, 
Arnautka and Kubanka, strains of the Kubanka have proved superior 
to Arnautka in yield, rust resistance, and milling and baking value. 
(8) Other durum varieties in some respects have proved superior to 
Kubanka. The Peliss has been the highest yielding spring wheat in 
the western portion of the Great Plains area. The Acme and Monad 
are superior to all other durum wheats except D-5 in rust resistance 
and are only slightly inferior to Kubanka in milling and baking value. 
They have also given higher yields, especially in rust seasons, than 
most other durum varieties. The D-5 variety is the most rust- 
resistant variety grown and has yielded only slightly less than Acme 
and Monad. Its milling and baking value, however, is the poorest of 
all varieties included in these experiments.
