PLATE 2 
Representative ears of unmarketable com. 
A. —Rotted ears. This classification includes not only totally rotted ears but also 
those that are partly rotted. Ears of the latter kind may be composed largely of good 
kernels, but when shelled the rotted portion would greatly reduce the market grade 
of the whole. 
B. —Chaff/ ears. There is some space between the kernels so that the ears can easily 
be bent and twisted. Such kernels are light and poorly developed and consequently 
have little market value. Chaffy ears that also showed signs of rot were placed in the 
rotted class shown in A because the rotting is more detrimental. 
C. —Nubbins. Although most of the kernels here shown would be good for feeding 
purposes, most of these nubbins would be missed by the average com husker. Further¬ 
more, a large percentage of nubbins is produced by weak diseased plants.
