occurrence and could not always be 
clearly distinguished from the kernels 
classed as light brown, no separate 
classification was made for them. It 
is possible that some of the kernels in¬ 
cluded in the variegated and red classes 
should have been classed as gray. Ker¬ 
nels having a grayish-brown color are 
shown in Plate 6, P. 
The data on the inheritance of ker¬ 
nel color are presented in Table IX. 
In general, the dark-colored kernels 
produced mostly dark-colored progeny, 
while the light-colored kernels tended 
to produce light-colored kernels in their 
progenies. The black parental kernels 
produced mostly dark-brown and black 
progeny kernels and a comparatively 
small percentage of light brown and 
red kernels. Brown kernels largely 
produced brown kernels of different 
shades and also about 26 per cent of 
reds and a few yellows. Red parental 
kernels produced about 69 per cent of 
red kernels in their progenies. Yellow 
kernels produced about 81 per cent of 
red kernels, and white parental kernels 
produced mostly red and yellow kernels 
in their progenies. While none of the 
colors appeared constant in breeding 
behavior, there was a rather definite 
relation between the color of the paren¬ 
tal and progeny kernels.
