TESTS OF BAKLEY VARIETIES IN AMEEICA 
73 
stations in Minnesota, The behavior of the hybrid barleys indicates that high- 
yielding 2-rowed sorts can be produced if desired. The Chevalier and Hanna 
barley's are not well adapted at St. Paul. This probably is caused by a disease 
factor, which might be overcome by crossing them with the more resistant 
Manchuria types. Manchuria (C. I. No. 244), which was widely distributed by 
the Minnesota station, was a very vigorous stock of barley. It produced high 
yields, not onl}^ at St. Paul but also at many stations to which it was sent. This 
barley is discussed elsewhere in this bulletin, as are several other varieties which 
were produced at Minnesota. In recent years the plats have been replicated and 
the varieties purified. Among the most promising of the new sorts are Man- 
churia (Minnesota No. 184; C. I. No. 2330), Minsturdi (C. I. No. 1556), Svan- 
sota (C. I. No. 1907), Aker (C. I. No. 1577), and Samofa (C. I. No. 1211). 
WASECA, MINN. 
Barleys were grown on the Southeastern Demonstration Farm and Substation 
at Waseca, Minn., from 1918 to 1921, inclusive. The annual yields, which are 
given in Table 29, were furnished through the courtesy of the Minnesota Agri- 
cultural Experiment Station. One of the best varieties at Waseca was the 
h3^brid C. I. No. 2935 (Minnesota No. 438). It was developed in the breeding 
experiments cooperative between the United States Department of Agriculture 
and the Minnesota Agricultural Experiment Station at St. Paul. This hybrid 
is a selection from a cross of Lion X Manchuria. It is of especial interest be- 
cause it is smooth av/ned. If Manchuria barleys with smooth awns could be 
developed they would be of great importance. The yield of this variety at 
Waseca is encouraging. Minsturdi (C. I. No. 1556), another hybrid, also yielded 
well. Manchuria (C. I. No. 2330), a selection made at the Minnesota station, 
was the most productive for the entire period. A selection of a French Chevalier 
gave good yields for this type of barley.

DXJLUTH, MINN. 
Barley varieties were grown on the Northeast Demonstration Farm and Sub- 
station at Duluth, Minn., during the years 1919, 1920, and 1921. The yields 
from these tests were furnished by the Minnesota Agricultural Experiment Sta- 
tion and are reported in Table 30. Of the nine varieties included four were 
grown for all of the three years. Svansota (C. I. No. 1907) was the best of these. 
This hybrid seemed to be particularly well adapted to the district about Puluth, 
having produced the highest individual yield in each of the three j^ears. Man- 
churia (C. I. No. 2330) was second in point of yield, while French Chevalier (C. 
I. No. 2900) was third. Two other Manchuria selections (C. I. Nos. 1478 and 
1189) yielded well in 1920 and 1921. 
The results at Duluth indicate that while Duluth is in a district that is best 
suited to barleys of the Manchuria type the summers are sufficiently cool to allow 
a normal development of varieties which do not grow normally in the higher 
temperatures to the south.
