Your Agriculture Colleges Have Found Hybrid Corn to Be the Best. 
5 
Double Crosses 
Double crosses are produced from four inbreds, so we take the product of the two single crosses 
using one as an ear parent and the other as a pollinator. This time we plant six rows of the ear 
parent and two rows as the pollinator, pulling the tassels from the six rows and fertilizing them by 
the two pollinator rows. The product from this double cross is the corn we sell you to plant. The 
other two rows are good only for feed or commercial purposes. 
Here you see how we produce an inbred. First, a good stalk of 
open-pollinated corn is selected—a good, strong, upright stalk with 
an ear starting at the proper height. You will notice the first year 
the ear is inbred, it becomes much smaller and the second year still 
smaller and so on until the fifth year of inbreeding when it is noth¬ 
ing but a nubbin with only a few grains of corn on the cob some 
times. 
Every inbred must be selfed or 
inbred at least five years before it 
can be certified, and some inbreds 
it takes longer than five years to 
get pure. In fact, some will break 
up even after they have been 
selfed seven or eight years. 
Note that these small ears are 
now all we have to start with to 
work back to make an ear of corn. 
This is one of the reasons why 
Hybrid corn can never be produced 
at a low cost. Our seed to plant 
this year is worth over $6,000, and 
will cost us $1,250 to have the seed 
certified, and this only the beginning of the cost of production. 
You will notice now that in order to make a Hybrid, we must take 
first, two inbreds, the grandpa and grandma to make a single cross 
or the mother. We must also take two more inbreds, grandpa and 
grandma to make a single cross to make the father. These two 
double crosses, father and mother, are now used to produce the 
corn which we sell to you for planting. 
Every ear of Hybrid corn is just like a child, having two grand¬ 
fathers, two grandmothers, a father and a mother.

This is a new Hybrid which we produced first for 
commercial purposes this year. While we are sold out 
of it at this time for seed purposes, we are holding 
back a small quantity which we will furnish free so 
long as it lasts—5 pounds with a 5 bushel order of Hy¬ 
brid corn, total of any or all varieties. 
We think this is the best Hybrid we have but only 
had a limited amount of about 200 bushel. We are 
putting in a large acreage of this Hybrid for next year, 
and are very anxious for you to try it, which will be 
enough to give you some idea what this Hybrid will do. 
It has the darkest green color of any corn we have 
ever seen, so dark green that it really looks black. 
Good heavy stalk, very stiff. Stands up exceptionally 
well. Long ears. Full season—should be planted by 
the 10th of May as it requires about 120 days to 
mature. Usually one ear. Adapted to North Central, 
Central and South Central sections. Dark yellow color. 
Ears about 11 inches long. Good depth grain. Well 
filled at both tip and butt. Easy to husk. Has a short 
shank, good for mechanical pickers. Not priced be¬ 
cause we have no more to sell. 
All corn is treated with Semesan, Jr., which will increase yields enough extra to pay for the cost 
of the seed.
