HISTORY OF KUBANKA WHEAT. 
The Kubanka variety of durum wheat is of Russian origin. Severa! 
importations have been made. The principal introduction (S. P. I. 
No. 5639, C. I. No. 1440‘) was made in 1900 by M. A. Carleton, then 
Cerealist of the United States Department of Agriculture, from Uralsk 
Territory in Russia. The original seed was grown under contract in 
1901, and seed was distributed from then until 1909 by the United 
States Department of Agriculture and later by the North Dakota 
and South Dakota Agricultural Experiment Stations. 
ADAPTATION. 
Kubanka is the most widely adapted variety of durum wheat 
grown in the United States. It is also the one most extensively 
grown, with the possible exception of Arnautka. The grain of Ku- 
banka is of good quality for the manufacture of semolina and alimen- 
tary pastes, the principal use of durum wheat. Kubanka also is the 
best durum variety for bread making. 
Kubanka is fairly resistant to black stem rust and to drought. It 
is less resistant to rust than the resistant varieties, Acme, Monad 
(D-1), and Pentad (D-5). Recent investigations, still unpublished, 
show that these three wheats are technically inferior to Kubanka in
