The Marquis outyields the other Fife wheats or equals them in 

 yield at all these stations except Williston, N, Dak., and Akron, 

 Colo. At Wilhston the Power and at Akron the Ghirka Spring out- 

 yield the Marquis variety, but by only 2.5 and 4 per cent, respectively. 



The Marquis outyields the Bluestem wheats at all stations except 

 WiUiston, N. Dak., where the Dakota Bluestem very slightly exceeds 

 it. The Marquis was damaged more than the other varieties by a 

 late spring frost at Wilhston in 1915. This caused the lower average 

 yield at this point. 



The Marquis outyielded all varieties of the Preston group every- 

 where except at Moccasin, Mont., and Akron, Colo. At Moccasin 

 the Fretes and at Akron the Red Russian outyielded the Marquis, 

 but by only about 3 per cent in each case. 



From these facts it is seen — 



(1) That winter varieties are best where they can be grown in the northern section 

 of the Great Plains area. 



(2) That durums are better than any spring common wheats in this section. 



(3) That the Marquis variety is better than any of the spring common wheats at 

 some stations and about as good as any at most stations. The Marquis ia a safe 

 variety to grow anywhere in this section when spring wheat is to be grown. 



The Marquis variety is especially well adapted to central South 

 Dakota, Here drought and rust often reduce the yields of later 

 maturing varieties. The Preston (''Velvet Chaff"), a bearded wheat, 

 is now the leading variety in that district. The Marquis is beardless 

 and a better yielder, as weU as a better milling wheat. 



Rust and drought are not so frequent in North Dakota ajid Montana. 

 The earhness of the Marquis variety gives it an advantage when they 

 do occur. The later maturing Fife and Bluestem varieties may give 

 as high average yields in a longer series of years. 



Results in the Western Basin and Coast Areas. 



The dry lands of the States west of the Rocky Mountains are 

 included under this heading. The different sections represented are 

 known as the Great Basin, the Snake River basin, the Harney Valley, 

 the Columbia Basin, and the Sacramento Valley. They include, 

 therefore, the States of Utah, Idaho, Washington, Oregon, Nevada, 

 and northern California. 



Marquis wheat has been introduced commercially at a few places. 

 Several carloads of seed are known to have been sold in the Columbia 

 Basin counties of Washington. Similar introductions may have 

 occmred in the Snake River basin also, but no record of such action 

 is known. It is doubtful whether the variety has been introduced 

 elsewhere in these areas. No statistics of production are available, 

 but the total quantity must be very small.
