EXPERIMENTS WITH MAEQUIS WHEAT.

ciates. The Marquis variety has been grown during three years, 1913 

 to 1915j inclusive, and the annual and average yields of this and 

 other varieties are shown in Table VII. The average yield of each 

 variety is given graphically in figure 3. 



The data show, that the Marquis outyields any of the other three 

 varieties, representing three separate groups of wheat. It excels the 

 Kubanka by only 5 per cent, but exceeds the Preston and Bluestem by 

 25 and 30 per cent, respectively. Two plats of Marquis wheat were 

 grown each year, the original seed having been received from separate 

 sources. The yields given are an average of the yields of the two 

 plats. The Glyndon, a Fife variety, was grown in 1913 and yielded 

 17.4 bushels to the acre, while the two Marquis plats yielded 20.5 

 and 22.3 bushels, respectively. Winter wheat has not been grown 

 successfully in this part of Minnesota.

Two facts are shown clearly by figure 3 and Tables III to VII, 

 inclusive, on which figure 3 is based. These facts are (1) that where 

 hard red winter wheats of the Crimean group can be grown in this 

 section they outyield any spring wheat, and (2) that Marquis wheat 

 outyields other varieties of spring wheat at all these stations. These 

 results are based on 3-year tests at all stations except Iowa, where 

 they cover only two years. 



The gain m yield of the Marquis over other spring wheat varieties 

 belonging to the Fife, Bluestem, and Preston groups is small. At 

 St. Paul, Minn., and Lincoln, Nebr., the difference is only about IJ 

 bushels. In central Iowa and eastern South Dakota it is 3 to 4 

 bushels. At Crookston, Minn., however, the difference is about 7 

 bushels. The gain in yield of the Marquis over durum wheats at the 

 three northern stations in this section varies from 1.5 to more than 

 5 bushels.
