EXPEKIMENTS WITH MARQUIS WHEAT. 



21 



spring conunon wheat. It outyields the Preston by only 3 per cent, 

 but the Power and Glyndon by 14 and 20 per cent, respectively, and 

 the Haynes by 19 per cent. 



RESULTS AT HIGHMORE, S. DAK. 



The Marquis variety has been included in the varietal experiments 

 at Highmore during three years, 1913 to 1915, inclusive. The annual 

 and average yields obtained from the Marquis and eight other 

 varieties are shown in Table XIII. The average yield of the best 

 variety in each group is shown graphically in figure 6. 



The Marquis has outyielded all other varieties, both winter and 

 spring, at Highmore during the period specified. The Kubanka and 

 Preston are nearly tied for second place and do not fall far below the 

 Marquis. The Kharkof, the hard mnter variety, and the Haynes 

 and three varieties of the Fife group fall from 4 to 11 bushels, or from 

 22 to more than 100 per cent, below the Marquis in yield. The 

 comparatively high yield of the Marquis variety in 1913 was due to 

 the favorable location of the plat in a low moist spot.

RESULTS AT EUREKA, S. DAK. 



At Eureka the Marquis has been grown in the varietal test during 

 only two years, 1914 and 1915. The annual and average yields are 

 shown in Table XIV. The best yielding variety in each group and 

 the average yield produced by it in the 2-year period are shown 

 graphically in figure 6. 



The results show that the Kubanka durum is the highest yielding 

 among the five varieties tested. It outyields the Marquis by 3.5 

 bushels, or 15.5 per cent. The Marquis ranks second, exceeding the
