EXPERIMENTS WITH MAEQUIS WHEAT. 
31 
The data show the marked superiority of the hard red winter 
wheats over any spring wheats at the Nephi substation. The Turkey 
variety surpasses the Marquis by 165 per cent and the leading spring 
wheat by over 100 per cent. The durum varieties exceed the 
Marquis in yield by nearly 20 per cent. In the Fife group the 
Marquis is exceeded by the Ghirka Spring by nearly 5 per cent. The 
Marquis is thus the lowest yielder among the six varieties considered. 
The yield of the Marquis in 1914 is from a 121-foot row; in 1915 it is 
the average of four tenth-acre plats. 
RESULTS AT ABERDEEN, IDAHO. 
The cooperative varietal experiments conducted at Aberdeen, 
Idaho, have included Marquis wheat only during the last two years, 
1914 and 1915. The annual and average yields of the Marquis and 
numerous other varieties are shown in Table XXII. The average yield 
of the best variety in each of the seven groups is shown graphically 
in figure 7. 
The outstanding fact shown by Table XXII is that here again the 
varieties of the hard red winter or Crimean group of wheats strongly 
outyield all spring wheats. Th&best variety exceeds the Marquis by 
110 per cent. The Fretes, Early Baart, and Palouse Bluestem, repre- 
senting three different groups of spring wheat, outyield the Marquis 
by 44, 39, and 31 per cent, respectively. Even the Little Club excels 
the Marquis in yield by nearly 8 per cent. Considering finally the 
Fife group, the Ghirka Spring exceeds the Marquis by 8 per cent, while 
the Power almost equals it in yield.
