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 aU sprmg wheats. The 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.

 grown at the Aberdeen (Idaho) Branch Experiment Station during 1914 and 1915.
