CEREAL EXPERIMENTS AT THE WILLISTON SUBSTATION.

an unnamed, variety of the Manchuria group grown locally near Willis- 

 ton. Since 1910, as noted in Table XVI, the yields reported are for 

 a pure-line selection from the original stock of Williston No. 170. The 

 average yields of two lots of Manchuria (Minn. No. 6, C. I. No. 638, 

 and Minn. No. 105, C. I. No. 643) for the seven years are 37.1 and 36.4 

 bushels, respectively. 



The Bernard (C. I. No. 881) is another local variety similar to Man- 

 churia. The average yield of this variety for the seven years is con- 

 siderably lower than that of the others here reported.

1 In 1910 and succeeding years the }'ields reported are those obtained from a pure-line selection from the 

 original Williston No. 170, "a variety of the Manchuria group. 



The average date of maturity of the 6-rowed varieties, as shown in 

 Table XVI, is July 26, which is one day earlier than that of Hanna 

 and seven days earlier than that of Success, the two 2-rowed varieties. 

 The average height of the 6-rowed varieties, 32 to 34 inches, is several 

 inches more than that of the 2-rowed varieties, an important matter 

 in diy-land farming, where barley and other grain is sometimes too 

 short to harvest with the binder. In weight per bushel the 2-rowed 

 varieties have exceeded the 6-rowed, the average weight of the former 

 being 17.2 to 47.7 pounds, while the four 6-rowed varieties vary from 

 } 1.9 to 16.6 pounds. 



TWO-ROWED v,\ KIKTIKS. 



The two J-rowcd varieties, Hanna (C. I. No. 203) and Success (C. I. 

 No. .v.»' ), as already stated, show a Lower average yield for the seven 

 years than any of the four 6-rowcd varieties included in Table XVI. 



The average yield for Hanna is 33.2 bushels and for Success .'!(). I 



bushels. The Hanna has yielded more, than the Williston No. 170 in
