Significantly discolored kernels are heat damage. The 
discoloration originates from the germ area (cotyledon) and continues through the sides and back of the kernel (endosperm) in a continuous band. Provided that the band is continuous, there is no minimum width requirement.
Kernel A: Shows the discoloration extending out of the germ (cotyledon).
Kernel B: Shows the discoloration around the sides.
Kernel C: Shows the discoloration across the back.
