Results in Iowa. 1 
yields of five strains of early yellow 
of oats grown at the Iowa Agricul- 
at Ames in cooperation with the 
of Agriculture during three or more 
years in the 11-year period from 1907 
to 1917, inclusive, are presented in 
Table XVII. 
The data presented in Table XVII 
indicate that the early yellow varie- 
ties, Kherson, Sixty-Day, and selec- 
tions from them, are the most de- 
pendable for Iowa conditions. The 
average yield of the original Kher- 
son in the 11 -year period from 1907 
to 1917, inclusive, is 52.9 bushels, as 
compared with similar averages of 
52.4 and 52.2 bushels for Myrick and 
Silvermine, respectively, the two 
highest yielding midseason varieties. 
However, since 1911 Richland, a se- 
lection from Kherson, has consist- 
ently outyielded all others. In the 
7-year period from 1911 to 1916, in- 
clusive, this selection has exceeded 
the original Kherson by 4.8 bushels, 
and the Silvermine, its nearest com- 
petitor of the midseason varieties, 
by 2.9 bushels in average yield per 
acre. Albion, a white selection from 
Kherson, has not been as promis- 
ing at Ames under central Iowa con- 
ditions, but is much more popular with 
farmers. A panicle and spikelets of 
Early Champion, an early white oat, 
are shown in figure 6.
