JACQUES HYBRID CORN 
Jacques Proven Hybrids are developed out of Hardy Northern varieties and are grown in ths fer- 
tile valleys of the Northern Mississippi River in Wisconsin and Minnesota. 
WHAT IS HYBRID CORN? 
The term “hybrid’’ does not refer to a cross of 
different varieties of corn, but to a cross between 
inbred lines or combinations of such lines. These 
inbred lines tend to perform the same way under 
like conditions, makirg it possible to predict their 
performance year after year. Commercial hybrids 
are double crosses made up by combining four dif- 
ferent inbred Strains. 
PRODUCTION OF HYBRIDS 
Production of a double cross hybrid corn is not a 
simple program of multiplication. The four inbred 
lines must be maintained year after year by hand 
polination. Each year two of the inbred lines must 
be crossed to form a single cross and the other two 
crossed in a Gifferent field. The second year two 
single crosses are combined to form a double cross 
by planting the raired combination in isolated 
fields, one row of the pollen parent to three of the 
seed parent. The plants in the seed rows are de- 
tassled before they shed any pollen. The ears from 
the detassled rows furnish the hybrid seed. 
DON’T SAVE SEED FROM HYBRID CORN 
Seed is not saved from a field of hybrid corn 
for the same reason that ‘“half-breed” pigs produced 
by crossing two different breeds of hogs are not 
allowed to breed with each other. It is common 
knowledge that if cross-bred hogs are mated to 
each other that the stock will “break-up’’ in the 
next generation. 
Since the plants in a field of hybrid corn are bred 
to each other because they are polinated among 
themselves, the seed saved from these plants will 
“break up’ in the following generation. This simply 
means that the “hybrid condition” obtained by com- 
bining inbreds is not self-perpetuating, that a hybrid 
ean not be continued under open polinated condi- 
tions. 
BY PLANTING JACQUES PROVEN 
HYBRIDS YOU CAN— 
Increase yields per acre—or plant an earlier corn 
without reducing the yield. This is frequently de- 
sirable when dry stalks as well as ripe ears are de- 
sired, for early shredding. 
Reduce harvest cost. 
Be surer of getting a crop despite adverse con- 
ditions. 
Get better quality grain. 
Get better quality ensilage. 
We Offer Hybrids Adapted to Every Section 
Select a Hybrid that will mature at about the 
Same time as the open pollinated Corn that you have 
been planting. Hybrids will mature slightly earlier 
and will yield more. If Hybrids are wanted for 
ensilage, select a Hybrid five to ten days later 
maturing than if wanted for grain.
