TESTS OF BARLEY VARIETIES IX AMERICA 61 
were published. An organization of farmers interested in the testing and growing 
of good barley in ^Yisconsin assisted in establishing farm culture of pedigreed 
varieties in the State, and this acted as an incentive to experiment-station workers 
to produce better varieties. Not only has very important work been done here, 
but the "Wisconsin station has been a distributing center of varieties, especially 
those of the Manchuria group. Many of these have been sent out under the 
names of Oderbrucker, Wisconsin Pedigree, and Silver King. In the earlier 
years of the "station a ^Manchuria barley was widely distributed, often under the 
spelling "Manshury." This has been changed to Mancliuria, principally to 
make it conform with varieties which have been widely tested at other stations 
and which also came from Manchuria. The history of this variety is given 
under C. I. No. 241 in a special paragraph elsewhere in this bulletin. 
Six groups of barley were compared, of which the Manchuria group was 
outstanding. The Hanna group, which was next in point of 3'ield, was much 
inferior to the Manchuria. The Thorpe, Chevalier, Horsford, and Hj'brid 
groups follow in the order named. 
It will be seen in the summarized digest of Table 27, in which eight varieties 
are compared, that barleys of the Manchuria group are as outstanding in their 
performance as was the group itself. The best varietv of the eight compared 
was Oderbrucker_ (C. I. No. 2700), though Manchuria (C. I. No. 2-11) was 
practicalh' equal in point of yield. The best of the other types compared was 
Svanhals (C. I. No. 187). Its yield was only 81 per cent of that of Oderbrucker. 
Hannchen (C. I. No. 531), which usually gives good juelds where barleys of 
the Hanna type are adapted, yielded only 61 per cent of that of Oderbrucker 
during the five years in which both were in the test. 
It is obvious that among so many varieties it is impossible to compare in 
detail all of the important ones. In recent years several varieties have been 
tested which have shown promise elsewhere. Charlottetown 80 (C. I. No. 
2732) was grown in the years 1917, 1918, and 1920. For these years its average 
yield was 50.6 bushels, vrhich was 102 per cent of the weighted mean of aU 
varieties. Manchurian (C. I. No. 739) was grown in 1907 and in the seven 
years from 1915 to 1921, inclusive. Its yield was 115 per cent of the weighted 
mean. Gold (C. I. No. 1145) was grown in the six years from 1915 to 1920, 
inclusive. Its yield was 91 per cent of the weighted mean. For the seven 
years from 1914 to 1920, inclusive, O. A. C. 21 produced an average yield of 
49.2 bushels, which was 107 per cent of the weighted mean. Of the varieties 
introduced into the test since 1912 O. A. C. 21 (C. I. No. 1470) seems to be 
especially promising, while Charlottetown 80 deserves consideration when it is 
compared with 2-rovred barleys. 
The results at Aladison show that barleys of the Manchuria-Oderbrucker type 
are especially suited to growing in Wisconsin. Although varieties of other 
types have been tested as extensively, they have not given sufficient promise to 
justify carrying many of them. Several varieties from the Wisconsin station, 
such as Wisconsin Pedigree (C. I. No. 835), Oderbrucker (C. I. No. 836), and 
Silver King (C. I. No. 890), have been widely tested over the United States and 
at many stations have given ver^' high yields. These varieties are discussed 
elsewhere.
