Kernels which are materially discolored by excessive respiration. The discoloration originates from the germ area and continues through the sides and back of the kernel (continuous band). Provided that the band is continuous, there is no minimum width requirement.
Illustration shows from left to right:
Kernel A: Shows the discoloration extending out of the germ.
Kernel B: Shows the discoloration around the sides.
Kernel C: Shows the discoloration across the back.
NOTE: For heat damage (drier) and heat damage in white corn refer to VRI C-5.0 and C-5.1, respectively.
