this shape have sufficient room for germ development and increase the 

 shelling percentage. Pointed, shoe-peg, and rectangular kernels should be 

 discriminated against. In thickness the kernels should number about six 

 to the inch in the row. 



(b) Uniformity. Odd shaped and irregular kernels throughout the body 

 of the ear are objectionable. Kernels should be uniform in depth, width, 

 thickness, and shape. 



(c) Space Between Rows and Between Kernels. Large open spaces 

 between rows either at the crowns or tips of kernels, or between the kernels in 

 the same row, are objectionable. There should be only sufficient space to 

 permit satisfactory drying of the ear. 



(d) Size and Condition of Germ. The germ should be long, wide, and 

 thick. Cut through the kernel from tip to crown parallel to the edges to get an 

 idea of the thickness of the germ. The germ should be smooth and bright, 

 not shriveled, blistered, shrunken, mouldy, or discolored. The embryo 

 proper should show a fresh, oily, and live appearance and be whitish in color. 

 Cut a longitudinal section parallel to the width of the kernel so as to expose 

 the embryo to view. 



SIZE OF COB. Size of cob varies with the variety and the locality in which 

 the corn is grown. For average conditions a medium-sized cob is most 

 desirable.
