average yield of Power is 1.6 bushels per acre higher than Marquis, 

 but because of the irregularities just mentioned this difference may 

 not be significant. Marquis is the leading variety of wheat in the 

 vicinity of Newell and, because of its high quality, earliness, and 

 short, strong straw, is probably to be preferred to other common 

 wheats for growing on irrigated land. The Kubanka, a durum 

 wheat, has outyieldecl all other varieties to such an extent as to make 

 it the most profitable variety. Even at the lower price obtained for 

 irrigated durum wheat, the net return doubtless will be higher than 

 from any of the common wheats.

. The Haynes Bluestem variety is late, easily injured hj rust, easily 

 shattered when ripe, and a rather poor yielder. The average yield 

 of this variety during the 8-year period is 6,6 bushels per acre less 

 than Kubanka. 



The Champlain variety, also called Pringle's Champion, is an 

 awned variety having semihard to hard red kernels. This wheat is 

 apparently of lower quality than Marquis, Power, or Haynes Blue- 

 stem. 



Two varieties of white wheats have been grown, but without much 

 success. The Regenerated Defiance was severely injured by rust in 

 both 1915 and 1916 and was discontinued from the experiments. The 

 Dicklow variety, a soft white wheat extensively grown under irriga- 

 tion in Idaho, was included in the experiments in 1919 only. It was 

 outyielded by all varieties except Marquis, which yielded the same.
