BULLETIN 402^ U. S. DEPARTMENT OF AGEICULTUIIE. 



It is a selection from Arnautka (C. I. No. 1494). If the datafor the 

 parent variety and the selection are combined, the average yield in 

 the 8-year period is 24,5 bushels, which would give it first rank. 

 At the present time the difference in yield in favor of any one variety 

 is not sufficient to be conclusive. A plat of durum wheat at the 

 station is shown in figure 5. 



Table XIII. — Annual and average yields of 44 varieties of spring wheat grown at the 

 Ahron Field Station, Akron, Colo., in the eight years, 1908 to 1915, inclusive.
