Chart 1. — Showing the significance of adaptation in corn production. At 
the left is shown the relative adaptation of a given lot of corn to two 
different environments. At the right is shown the comparative plant 
growth in a given favorable environment of two lots of corn adapted 
to two different environments. Compiled from Table 2. 
rather intermediate climate, corn from the less favorable sources 
matured well, while from the sources of more favorable climate 
the corn was immature and chaffy. 
Representative ears of corn from each source when grown 
in Lancaster and Kimball Counties are shown in figure 3. These 
data show some of the profound hereditary differences between 
native types from various climatic areas within the State. 
VARIETY SIGNIFICANCE 
Local adaptations within some of our standard varieties of 
corn are so marked that variety name has lost much of its sig- 
nificance in Nebraska. These distinct local variety types or sub- 
varieties originate thru the natural processes of adaptation and 
thru the controlled selections by man. These controlled selec- 
tions may be along the natural line of adaptation or to secure 
other economic advantages, or they are mere fanciful individual- 
istic variations without immediate practical importance.
