Funks Hybrid Corn 
Stands TJp Better—Yields More 
Funks Hybrid Corn 
How We Make Hybrid Corn 
About 20 years ago Funks started to inbreed 
from their best open-pollinated corn. To inbreed 
you must cover the young shoot with a small bag 
before any silks appear. Later, as the tassel de¬ 
velops, pollen is collected in a bag and dusted on 
the silks that have emerged and the shoot again 
protected from foreign pollen. 
After years of inbreeding, selection strains 
are developed that are strong rooted, stiff stalked, 
resistant to disease, resistant to cold, resistant to 
drought, and that have many other good features. 
These inbred strains alone, however, are rela¬ 
tively low yielding. Unrelated strains are crossed 
to obtain high yields lost during inbreeding. 
Trial crosses are made by combining two or 
more of the pure inbred strains. The crosses are 
grown and studied under a variety of conditions. 
Finally the best combinations are put on a 
commercial basis and offered to our customers 
for their use in growing more corn per acre and 
making a corresponding reduction in their cost 
of production. 
Production of Hybrid Corn is not as simple and 
easy as this short description might lead one to 
believe. Twenty years of controlled breeding. 
Years of work, moving ahead only to back up for 
a new start. Years of feeling the way. Years 
of making sure, so that when Hybrid Corn was 
offered to you we would be confident of its mak¬ 
ing good on your farm; more bushels per acre to 
lower your cost of production. 
Funks Seed Corn 
Over 30 Years Scientific Breeding 
Funks Hybrid Corn 
Yields More 
Proven by Farm Yield Trials 
Funks Hybrid 220 and Funks Hybrid 206, 
which this year replace our 365 and 517, mark a 
distinct advance in Hybrid Seed Corn production. 
These two new Hybrid recombinations were tried 
out for several years in our test plots and found 
to be higher yielding. They were taken to farm¬ 
ers fields many places in Illinois and found to be 
superior to the farmers’ own corn both in yield 
and in their ability to stand up. 
For earlier hybrids for the north and north 
central parts of the state we stand by with Funks 
Hybrid 915 and Funks Hybrid 779. These have 
continued to show up well in yield trials and under 
actual farm conditions. 
Funk’s corn-breeding program is constantly 
moving forward. Slowly at times it is true but 
forward nevertheless. Careful investigation must 
precede each step. Each new Hybrid must be 
tried out for several seasons under a variety of 
soil and climatic conditions. For your protection 
and for our own, we must be certain of every 
advance. 
We have confidence in the Hybrid Corn of¬ 
fered here. The future no doubt will bring to 
light something better. This is the best available 
in 1934. 
Detasselling Crew in Funks Seed Field — Hybrid Seed is 
Harvested Only from Detasselled Plants 
SEED CORN FROM FUNKS IS BETTER BECAUSE:— 
It is grown from disease-free seed. 
It is backed by years of scientific breeding. 
It is picked early and dried quickly in our modern, 
temperature-controlled driers. 
It is individually ear-selected, butted and tipped. 
It is double graded to insure uniform drop. 
IT HAS PROVEN ITSELF IN EVERY STATE 
AND COUNTRY WHERE CORN IS GROWN
