TESTS OF BAELEY VARIETIES I3Sr AMEEICA

LA FAYETTE, IND. 
The annual yields of the barley varieties grown at Purdue University, La 
Fayette, Ind., were furnished through the courtesy of the Indiana Agricultural 
Experiment Station. These yields, which extend over a period of 17 years, are 
reported in Table 24. Success Beardless (C. I. No. 1808) was the only variety 
carried in the test for the entire period. Its yield was 104 per cent of that of the 
weighted mean of all varieties. Ovring to the fact that many varieties were 
discarded after the harvests in 1909, 1914, and 1917, it is easier to discuss their 
relative value by periods. In the years 1905 to 1909, inclusive, Silver King 
(C. I. No. 890) and Manchuria (C. I. No. 241) were the best of the nine varieties 
grovv-n. From 1908 until 1914 only three varieties, all of which were fully com- 
parable, belong to the Manchuria group. Of these, O. A. C. 21 (C. I. No. 1470) 
was the best. Hannchen (C. I. No. 531) produced the highest yield of the 
nine varieties discarded after 1917. Unfortunately there were no barlej^s of the 
Manchuria group in the test for the^ years 1915, 1916, and 1917. Ilannchen 
was in the test for four of the years in which O. A. C. 21 was grown and was 
better than O. A. C. 21 in three of these years. The difference in yield, however, 
was very small. 
Hannchen was not grown in 1919, 1920, and 1921, when varieties of the Man- 
churia group were included in the experiment. During the years 1917 to 1921, 
inclusive, 10 barleys were tested one or more years. Charlottetown 80 (C. I. No. 
2732) was the most promising of those grown for the full five years. Manchuria 
(C. I. No. 2330), a selection made at the Minnesota Agricultural Experiment 
Station, was the best of the five varieties that were carried for three years. 
Lion (C. I. No. 923), introduced in 1920, gave relatively high yields for two 
years, while Featherston (C. I. No. 1120) was by far the best variety in 1921, 
the only year in which it was grov/n. These results indicate that the Manchuria 
barleys are the ones best adapted to this section of Indiana. This agrees with 
the results in the neighboring States and with v/hat is knovrn of the ecological 
adaptation of varieties. The Manchuria barleys are adapted to climates v/here 
the ripening season is warm and humid without excessive heat. Barleys of the 
Hanna and Chevalier groups grow best in cooler regions. That the Charlotte- 
town 80 has done well not only at La Fayette but at many other points in the 
Mississippi Valley is proof that this selection differs materially from the original 
Chevalier of England. Primus (C. I. No. 532), a barley of the Thorpe type, 
was very low in productivity. This variety must have a cool ripening season 
before good yields are secured. It is of especial interest that high jaeids were 
obtained from Success Beardless (C. I. No. 1808), a barley of the Horsford group. 
It was the only variety carried for the entire 17 years. In each of the four 
periods it was one of the better sorts.

URBANA, ELL. 
The Illinois Agricultural Experiment Station at Urbana furnished data as to 
the yields of the barley varieties tested there for the seven years from 1915 to 
1921, inclusive. These are reported in Table 25. Six varieties were tested 
during this period. Of these, Oderbrucker (C. I. No. 836) was in the test for 
the full seven years. Unfortunately few types of barley were included. The 
only 2-rowed barley was Montana (C. I. No. 3118), which was probably a Cheva-
