EXPERIMENTS WITH MARQUIS WHEAT. 
25 
RESULTS AT MOCCASIN, MONT. 
The varietal experiments at Moccasin have included Marquis 
wheat during the 3-year period, 1913 to 1915, inclusive. The 
annual and average yields obtained are given in Table XIX. The 
average yield of the leading variety in each group is shown in figure 6. 
The hard red winter wheats of the Crimean group outyield all 
spring wheats at Moccasin by a margin of over 6 bushels per acre. 
Among the spring wheats the durums do not outrank the spring 
common wheats, as they have done at most of the other stations; 
in fact, the best varieties of durum, Fife, and Preston wheats are 
practically equal in yield. The Marquis leads the Fife varieties by 
a margin of over 5 per cent. The leading variety of durum wheat 
and the leading variety of the Preston group of common wheat 
outyield the Marquis, however, by the narrow margins of 1 and 3 
per cent, respectively.

CONCLUSIONS. 
The graphic portrayal in figure 6 and the facts given in Tables IX 
to XIX, inclusive, show that winter wheat is decidedly better than 
any spring wheat in much of this section. In central South Dakota 
and North Dakota, however, winter wheat can not be grown suc- 
cessfully. 
Among spring wheats, the durums outyielded all the groups of 
common wheat at all of these stations, except Moccasin, Mont., and 
Highmore, S. Dak. At all the stations except Highmore, in central 
South Dakota, the durum wheats outyielded the Marquis variety. 
At Highmore the high yield of the Marquis wheat was due to the 
specially favorable location of the Marquis plat in a low spot in 1913. 
At Moccasin, Mont., however, the yields of the Marquis and the best 
durum variety were about equal.
