White wheats are represented by the very light colored wheats 

 grown largely on the Pacific coast. Bleached wheat may be 

 kernels of any color which have been badly discolored by 

 adverse weather conditions. Make a study of the color by 

 separating the sample into the following groups: light 

 amber, amber, dark amber, yellow, white, and bleached. 

 Weigh, and record the weight and per cent in each group. 

 The total for color should be 100 per cent. 



Texture. Texture in wheat may be classed as hard, 

 medium, and soft. Texture is closely associated with color. 

 Amber-colored wheats are usually hard in texture. Wheats 

 that have a tendency to become yellowish are usually of a 

 medium texture. Wheats that are yellow or white are likely 

 to be soft. Texture may also be determined by crushing 

 typical kernels. 



Make a study of the texture by separating the sample into 

 the following groups : hard, medium, soft. Weigh, and record 

 the weight and per cent in each group. The total for tex- 

 ture should be 100 per cent. 



Size. Divide the sample into the following groups : 

 large kernels, medium kernels, and small kernels. Weigh 

 and determine per cent of each group. Record weight and 

 per cent in the blank form. The total for size should be 

 100 per cent. 



Separate from the sample 100 average-size kernels. Weigh 

 and record weight. Compare the weight of 100 average-size 

 kernels in the different samples studied. The size of kernels 

 differs in different classes of wheat. 



The weight per bushel is determined by using the weight- 

 per-bushel tester. Determine the weight per bushel of the
