White Russian, both later varie- 
ties, yielded considerably less. The 
Sixty-Day selection, C. I. No. 626, 
has given the highest yields of any 
of the varieties since it has been 
included in the experiments. Dur- 
ing the eight years from 1912 to 
1919, this variety averaged 2.4 
bushels per acre more than Kher- 
son. This variety has a white hull, 
but usually has a low weight per 
bushel. 
The Sixty-Day variety. C. I. No. 
165, has been grown in all years 
except 1914. During this period 
it has averaged nearly the same as 
Kherson, with which it is practi- 
cally identical. The Burt variety. 
C. I. Xo. 293, has been continued 
in the experiments since 1912. 
The average of Burt was the same 
as for Kherson. The Burt variety 
as grown is a mixture of various 
colors of kernels. 
The Sixty-Da} 7 selection, Xo. 
165-566, has yielded slightly less 
than Kherson or the parent va- 
riety, Sixty-Day. It has a white 
kernel of good quality, however. 
The Richland and Albion varieties 
have been included in the experi 
ments since 1916, but have not 
yielded as high as the other early 
varieties. 
Table XIX shows the average 
data recorded on the dates of head- 
ing and maturity, the height, 
weight per bushel, and the yields 
of grain and straw for the three 
varieties of oats which were grown 
during the entire 12-year period. 
The average yields of these three 
varieties are shown graphically in 
figure 10. The yield differences are largely due to the greater earli- 
ness and shorter straw of Kherson. This variety has an average.
