IMPEOVEMENT OF GHIEKA SPRING WHEAT.

tent and yield of straight flour, and it showed the greatest loss in 

 milling. The low yield of flour and the loss in milling are especially 

 pronounced. This is partly due to a peculiar flufliness of the Ghirka 

 flour. The Haynes gave the highest yield of straight flour and tied 

 Kubanka for the highest score in texture of loaf. The Rysting had 

 the highest percentage of crude protein in the wheat and the best 

 color of loaf. 



The data for 1914 show that the Ghirka is the poorest in crude- 

 proteui content and color and texture of loaf and shows the greatest 

 loss in milling. The Haynes leads in crude-protein content and tex- 

 ture of loaf. Tlie Glyndon yields more straight flour, produces- the 

 best volume of loaf, and ties with the Haynes in color of loaf. 



The 3-year average of these data shows that the Ghirka variety 

 has not compared favorably in quality with standard Bluestem, Fife, 

 and durum wheats. It ranks relatively low in market grade, in 

 crude protein, color and texture of loaf, and yield of straight flour, 

 and has a large loss in milling. The volume of loaf is usually good, 

 although averaging less than that of Bluestem.
