In the progenies of these 63 self-pollinated ears that 
were heterozygous for pericarp color, there were approxi- 
mately 2.5 plants with pericarp color to one without it. 
All the classes of grains from self-red to non-red yielded 
both colored and non-colored ears, thus indicating, as 
already shown by East and Hayes, that the somatic varia- 
tion in the seeds does not change their hybrid character. 
Considering only the plants with pericarp color, in the 
progenies of both heterozygous and homozygous varie- 
gated ears, 106 progenies in all, marked differences are 
seen in the percentages of self-red ears from seeds of the 
different color classes, as follows :

6 Some of these ears had what I have termed ' ' half -red ' ' pericarp, i. e., 
pericarp with a reddish color extending part way from the base to the 
crown of the seeds. (See Ann. Ept. Nebr. Agr. Expt. Sta., 24: 62. 1911.) 
Half -red differs from self -red and variegated red not only in distribution 
but also in almost never developing fully in the heterozygous condition. It 
is hypostatic to self-red, but shows between the red stripes of variegated 
seeds. Since its presence does not mask either self -red or variegated-red 
and since it is strictly allelomorphic to both of them, half -red is here in- 
cluded with non-red. Variegated ears have never, in my observation, pro- 
duced half -red grains as somatic variations. 
" Some of these were half -red. (See footnote 6.)
