From Table XI it is scon that several varieties appear to be better 

 than the Pacific Bluestem from the standpoint of }~icld. The Early 

 Baart exceeded that variety during the five years by an average 

 yield of ;; bushels per acre. The Koola variety exceeded the Bluestem 

 in the 3-year average yield by 6.3 bushels per acre, and for the same 

 period the Karun exceeded the Bluestem by 4.9 bushels per acre. 



In Table XII the leading spring wheats grown at the Moro sub- 

 station during 1913, 1914, and 1915 are arranged in several classes, 

 showing the average yield for each variety and for each class.

Table XII shows that the durum wheats apparently are not so well 

 adapted to the Columbia Basin region as are the common and club 

 varieties. The bearded varieties of common wheats exceeded the yield 

 of the beardless common and club varieties by 1.7 bushels per acre, 

 and the average yield of all common and club wheats exceeded the 

 average yield of the two durum varieties by 3.5 bushels per acre. 



DESCRIPTIONS OF THE BEST VARIETIES. 



The six varieties of spring wheat which have given the best average 

 results are described and discussed below. Of these varieties, Pacific 

 Bluestem and Little Club are well known and widely grown west of 

 the Rocky Mountains. Early Baart is grown commercially to a small
