RELATION OF KERNEL TEXTURE TO WHEAT 6 
grown at the United States Plant Introduction Station, Chico, 
Calif., and the latter at the agricultural experiment station, Lincoln, 
Nebr. 
The two durum wheat samples tested bear the M. I. Lab. Nos. 
7401 and 7402. These both represent true varietal wheats grown 
at the agricultural experiment station, St. Paul, Minn. Sample 
No. 7401 was of the Arnautka variety and 7402 of the Kubanka 
variety. 
In addition to the results given in tabular form, graphs are pre- 
sented for some of the more important factors discussed, that the 
results may be more readily compared and that the extent of the 
differences may be more apparent. 
PHYSICAL CHARACTERISTICS OF KERNELS OF DIFFERENT 
TEXTURES 
In Table 1 data are presented that show the test weight per bushel 
of the cleaned wheat in each separation before scouring, the test 
weight after scouring, the weight per thousand kernels, and the 
specific gravity.
