Figure 6 shows the whiter-wheat varieties grown hi replicated fiftieth- 
acre plats in 1915. 
In the fall of 1912 and of each succeeding year the seven leading 
varieties of whiter wheat were seeded on acre plats. This change 
was made hi order to test these varieties on a large scale under

from the acre plats were not as high as the yields of the same varieties
