PLANT Cotors IN Maize 9 
be concerned in plant-color development. . He had earlier (1911) announced 
some of the plant colors discussed in the present paper and placed on 
record some evidence as to their genetic behavior. Gernert (1912) 
described types of maize that differ widely in color of anthers, glumes, 
silks, sheaths, and husks, and reported simple mendelian behavior in F, 
and F, of certain crosses. With this exception, Gernert’s extensive investi- 
gation of plant-color types has not been reported, but the writer has been 
able, thru an exchange of material, to compare some of Gernert’s types 
with those in his own cultures. 
SOURCE AND DESCRIPTION OF MATERIALS USED 
The plant-color types discussed in this paper came in the main from 
the crossing of two little-known varieties, one of which was obtained at a 
national corn exposition and the other from an exhibit at a local agri- 
cultural fair. One of the color types produced by this cross is the same as 
that of the dent varieties generally grown thruout the Corn Belt; a second 
is not infrequently seen in certain pop, flint, and sweet corn varieties; 
and a third occurs in the fields of flour corn of certain Indian tribes of 
the Southwest. One of the color types produced by the cross had no 
existence, so far as the writer knows, until it appeared in his cultures. 
Modifications of several of the six color types noted above have been 
produced by crossing with a color type common in a few varieties of 
sweet corn and closely related to the type most common in field maize. 
The principal color types concerned in this account are discussed in some 
detail in the descriptive notes below. They are: 
I — Purple 
Il — Sun red 
III — Dilute purple 
IV — Dilute sun red 
V — Brown 
VI — Green 
PURPLE, TYPE I 
Material of the purple type was first obtained as a single ear from a 
local agricultural fair at Nehawka, Nebraska, in 1906. The varietal 
name is unknown. The uncrossed stock was a smooth-seeded pop corn
