Of all the varieties tested. the 2-rowed varieties Hannchen and 
Svanhals have proved best adapted to the conditions at Dickinson. 
THE 2-ROWED HULLED GROUP. 
Hannchen.—The Hannchen barley (C. I. No. 531) was obtained by 
the United States Department of Agriculture in 1904 from the 
Swedish Plant-Breeding Association, Svalof, Sweden. This pedi- 
greed variety was originated at Svalof. It is a selection from the 
lic. 6—Heads of five varieties of barley grown at the Dickinson substation: From 
left to right—-(1) Svanhals, (2) Hannchen, (3) Gatami, (4) Manchuria, and (5) 
Nepal. 
Hanna variety, which was imported from the famous barley district 
of that name in Mahren, Austria. On account of its relatively small 
straw and sparse leaf development it can withstand drier weather 
than most varieties. It has been under trial at Dickinson six years 
(1908 to 1913) and during that period has given the highest average 
vields of all varieties tested, 35.2 bushels to the acre. The parent 
variety, Hanna. during the same period has averaged 32.9 bushels, 
a gain of 7 per cent in favor of the pedigreed variety.
