HYBRID CORN 
Hybrid Corn is really corn that is 
“made-to-order . 
It is produced by 
crossing inbred lines. 
The first requisite of a hybrid corn program, therefore, is to develop 
inbred lines. 
several generations. 
from a plant to the silks of the same plant. 
These lines are obtained by self-pollinating the plant for 
Self-pollination is accomplished by applying pollen 
These inbred lines are of 
little value until they are crossed with another unrelated inbred line 
which produces the hybrid. 
The hybrids produced are markedly 
superior to the original varieties. 
Despite the newness of Hybrid 
Corn, yield comparisons in many 
corn belt states have demonstrated 
the superiority of certain hybrids 
over the best standard open-polli- 
nated varieties. 
Every grower is interested in ob- 
taining large acre yields, and Hy- 
brid Corn does yield more. The net 
profit from growing a bushel of 
corn is the difference between the 
U.S. 13 
cost of production and the selling 
price. Costs of producing an acre 
of corn are relatively constant, re- 
gardless of yield. The cost per 
bushel, therefore, is materially re- 
duced with large acre yields. 
Hybrids have a narrower range of 
adaptation to climatic conditions 
than the standard varieties, there- 
fore when you purchase your Hy- 
brid Corn it is important that you 
get corn which is suited to your 
location. 

Smooth, deep-kerneled ears which have a bright orange tinge. Responds
