MORRIS, MINN. 
Barlej^ varieties were tested on the West-Central Experiment Farm at Morris, 
IN.linn., from 1918 to 1921, inclusive. The yields reported in Table 33 were fur- 
nished by the Minnesota Agricultural Experiment Station. The highest yields 
were obtained from varieties of the Manchuria type, of which INIanchuria (C. I. 
No. 2330) and Manchuria (C. I. No. 1189) were probably the best. Svansota 
(C. I. No. 1907), the best of the hvbrids, producect an average yield slightly less 
than that of Manchuria (C. I. No. 2330). The selection of French Chevalier 
(C. I. No. 2900) was better than the average at INlorris. Although the varietal 
tests have been run only four years it is quite apparent that barleys of the Man- 
churia type are particularly well adapted to cultivation in this section. 
AMES, IOWA 
Varietal tests of barley were conducted at Ames, Iowa, in cooperation vdth the 
Iowa Agricultural Experiment Station from 1913 to 1921, inclusive. Ten 
varieties were tested, and all of them were carried in the experiment for the 
entire period. The annual j'ields are reported in Table 34. Through 1917 the 
yields were figured to check. From 1918 to 1921, inclusive, actual yields are given. 
The best two varieties v/ere Oderbrucker (C. I. No. 1272) and Oderbrucker 
(C. I. No. 2700). Oderbrucker (C. I. No. 1272) is a pedigreed variety developed 
by the Wisconsin Agricultural Experiment Station under the pedigree No. 5. 
O. A. C. 21 (C. I. 1470) was third in point of yield. Like the Oderbrucker bar- 
leys it belongs to the Manchuria group. Following O. A. C. 21 is Manchuria 
(C. I. No. 241). 
The 2-rowed varieties tested, Frankish (C. I. No. 295) and Hanna (C. I. No. 
203), are barleys belonging to the Hanna group. Frankish gave an average 
yield of 111 per cent of the weighted mean, but was only fifth in point of yield. 
Hanna was quite inferior to Frankish, exceeding only the low-yielding hull-less 
and hooded varieties. Caucasian (C. I. No. 90), a Russian 6-rowed bearded sort, 
differing greatly from Caucasian (C. I. No. 2724) grown in Canada, gave fairly 
good yields, but was also surpassed by the Manchuria barleys. There is no 
question as to the types of barleys best suited to this district."' The barleys of 
the Manchuria group are outstanding in yield at Ames, as they were in Wis- 
consin and Minnesota. For many years Oderbrucker has been the predominating 
variety grown on the farms in Iowa.
