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. These lines are obtained by self-pollinating the plant for 
several generations. Self-pollination is accomplished by applying pollen 
from a plant to the silks of the same plant. 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 cost of production and the selling 
superior to the original varieties. 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. 
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-
