SCORE CARD FOR OATS 195 



the germination is taken into account. A good example of 

 score cards of this kind is the one used by the College of 

 Agriculture of the University of Wisconsin. 



SCORE CARD FOR OATS 



Trueness to type or breed characteristics 5 points 



Uniformity in size and shape of kernels 10 points 



Color of grain 5 points 



Freedom from mixture with other grains 5 points 



Size of kernel 10 points 



Per cent and nature of weed seed, dirt, and other 



foreign material 15 points 



Odor — musty, smutty, sulphur 15 points 



Weight per bushel 10 points 



Percentage of meat to hull 10 points 



Viability 15 points 



Total 100 points 



LABORATORY AND FIELD EXERCISES 



1. If material is available either from the field or from stored 

 samples, write a complete description of the mature oat plant. 



2. Each student should bring in a sample of threshed oats and care- 

 fully weigh out a portion of it. Then separate the whole grains from 

 the weed seeds, chaff, and broken grains, and weigh each lot and figure 

 the percentage of good seed. Now divide the whole grain into large 

 and small kernels and figure the percentage of large, strong grains which 

 the sample contains. 



3. Take samples of the large and small grains and make a germi- 

 nation test. Study the differences in the growth of the two sets of 

 plants carefully. It might be well also to grow small plats from large 

 and small kernels on the experimental grounds, making careful note of 

 any differences in vigor of growth. 



4. Make up solutions of formaldehyde, mixing it with water in the 

 proportions of 1 to 400, and 1 to 200. Figure how many gallons of water 

 would be used to 1 pound (a pint) of formaldehyde at each of these 

 rates. Treat small lots of seed for smut in each of the following ways: 



(1.) No treatment. 



(2.) Soak 15 minutes in the 1 to 400 solution. 



(3.) Soak 15 minutes in the 1 to 200 solution. 



(4.) Soak 30 minutes in the 1 to 400 solution. 



(5.) Soak 30 minutes in the 1 to 200 solution. 



(6.) Sprinkle till thoroughly wet with the 1 to 400 solution. 



(7.) Sprinkle till thoroughly wet with the 1 to 200 solution.
