The ten ears of the sample 

 should possess similar or like 

 characteristics and should be 

 true to the variety which they 

 represent. 



The shape of the ear should 

 conform to variety type, taper- 

 ing slightly from butt to tip, 

 but approaching the cylindrical. 



Color of gram should be true 

 to variety and free from mix- 

 ture. White corn should have 

 white cobs, yellow corn red cobs. 



The ears should be sound, firm, 

 well matured and free from 

 mold, rot or insect injuries. 



The tips of the ears should not 

 be too tapering and should be 

 well filled with regular, uniform 

 kernels. 



The rows of kernels should 

 extend in regular order over the 

 butt, leaving a deep impression 

 when the shank is removed. 

 Open and swelled butts are ob- 

 jectionable. 



The kernels should be uniform 

 in shape, size and color, and 

 true to the variety type. The 

 kernels should be so shaped that 

 their edges touch from tip to 

 crown. The tip portion of the 

 kernel is the richest in protein 

 and oil, and hence of the high- 

 est feeding value. For this rea- 

 son the tip portion should be 

 full and plump. 



Northern section 8*4 to Wz 

 inches, central section B% to 9% 

 inches, southern section 9 to 10 

 inches. Long ears are objection- 

 able because they usually have 

 poor butts and tips, broad, shal- 

 low kernels, and hence a low 

 percentage of corn to cob. 



Northern section 6% to 7 

 inches, central section 6% to 7% 

 inches, southern section 7 to 7% 

 inches. 



The furrow between the rows 

 of kernels should be sm^H. 

 Space between kernels near the 

 cob is very objectionable. 



The proportion of corn to cob 

 is determined by weight, depth 

 of kernels, size of cob and ma- 

 turity all affect the proportion.
