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 Ioav weight per 

 bushel. 



The Sixty-Day variety, C. I. No. 

 165, has been grown in all j^ears 

 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. No, 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-Day selection, No. 

 165-566, has yielded slighth^ less 

 than Kherson or the parent va- 

 riety, Sixty-Day. It has a white 

 kernel of good quality, however. 

 The Eichland 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 graphicall}^ in 



figure 10. The yield differences are largely due to the greater earli- 

 ness and shorter straw of Kherson. This variety has an averaga
