CORN JUDGING 91 



Circumference of Ear. The circumference of ear is 

 determined by measuring the ear one third the distance 

 from the butt to the tip. Small circumference of ear in- 

 dicates a small amount of corn. Ears too large in circum- 

 ference are likely to be immature, and are, therefore, of less 

 value. For such deficiencies the score should be decreased. 



Color of Kernel. A uniform color, true to the variety, 

 indicates purity. If there is a difference in color, or if there 

 are grains that differ in color from that of the variety stand- 

 ard, a mixture is indicated, and the score should be reduced. 



Color of Cob. Usually yellow varieties of corn have red 

 cobs, and white varieties have white cobs. If the cob is 

 not correct in color, a mixture is indicated, and the score 

 should be reduced. 



Butt of Ear. The butt of the ear should be well filled 

 out with kernels of uniform shape. 



Tip of Ear. The rows of kernels should extend the full 

 length of the ear, covering the tip with kernels of uniform 

 size and shape. 



Shape of Kernels. Desirable kernels should be wedge- 

 shaped ; that is, they should be wider across the crown than 

 at the tip of the kernel. The thickness should be about one 

 half the width, and they should have a large, well-developed 

 germ. The kernels on the different parts of the ear should 

 be uniform in shape and size. This is essential to secure 

 a uniform distribution in planting. 



Depth of Kernels. The amount of corn on an ear depends 

 largely upon the depth of the kernels. From this point 

 of view it would seem desirable to have as deep a kernel 

 as possible. Experiments seem to indicate, however, that
