SCORE CARD FOR WHEAT 



161 



While these colleges do not all agree as to the relative impor- 

 tance of each point, they do agree quite uniformly on the 

 important points. Any of these cards will serve the purpose 

 of calling attention to the important points that must be 

 considered in judging. 



SCORE CARD FOR SEED WHEAT 



LABORATORY AND FIELD EXERCISES 



1. Obtain samples of as many kinds of wheat as possible, and learn 

 to identify them. Note differences in weight, size and shape of kernel, 

 hardness of kernel, and color. 



2. Obtain samples of wheat from several farms; compare weight, 

 color, percentage of weed seeds, percentage of dirt, purity of sample 

 (that is, is it one pure variety or a mixture?), size and variation of 

 kernels, presence or absence of smut. 



3. Obtain an average sample of wheat; weigh out carefully one or 

 two ounces; count the kernels, then determine the number in one 

 pound, in on3 bushel. Find how many kernels per square foot there 

 would be if 1}4 bushels were sown evenly on an acre of land. If possi- 

 ble, count the number of plants found growing on one square foot in 

 a good field of wheat. How do you account for the difference? 



4. Visit several fields of grain just as they are heading out. Find 

 a head of wheat that is smutted; pull up the plant on which the smutted 

 head is growing, and carefully examine all the heads on the plant, 

 even if you must split the stem open to find some of the heads that 

 have not yet appeared. Examine several smutted plants in this way. 

 Are all the heads of a plant usually smutted, or are only part of them?
