Program is the testing of new hybrids. Last 
season several hundred new hybrids were 
tested in Funk's own hand planted Performance 
Plots with replicated plantings. Plots were dis¬ 
tributed at eighteen points covering 400 miles 
north and south and 800 miles east and west. 
New hybrids showing promise will be tested 
again. Others will be discarded. Trial hybrids 
graduate to commercial production only after 
they have proven their outstanding perform¬ 
ance for several years and over a wide area. 
"The Best Hybrid First From Funk" means ex¬ 
actly what it says because Funk High-Yield¬ 
ing Hybrids are built on the firm foundation of 
sound scientific investigation and on proven 
superiority based on facts. 
Selfing or inbreeding corn means using the 
same individual plant as both male and female 
parent. This is accomplished (using bags) by 
dusting pollen — male germ plasm — from the 
tassel of a plant on the silks — female germ 
plasm — of the same plant. 
Inbred strains are developed from open-polli¬ 
nated corn varieties by successive years of self- 
pollination and selection to separate from the 
mixed open-pollinated variety superior pure 
types (Inbred Strains) for use in controlled 
cross-pollination for Hybrid Corn production. 
Cross-breeding is accomplished by taking 
pollen from the tassels of one kind of corn (in- 
bred, or single cross), and dusting it on the (pro¬ 
tected) silks of another unrelated kind of corn 
(inbred or single cross). A cross between two 
seifs or inbred strains is known as a single cross 
while a cross between two single crosses is 
known as a double cross. 
THE MAIL BAG SAYS:— 
Lake County. Indiana: I'm only a small one horse 
farmer but I do love to raise good crops and in a life¬ 
time of farming, that bushel of Hybrid Seed I got from 
you last spring produced by far the best corn I ever 
raised. 
Marshall County. Illinois: I am more than pleased with 
the results. The average yield will be approximately 
100 bu. per acre. 
McDonough County. Illinois: The Hybrid seed I pur¬ 
chased from you germinated splendidly. On October 
9, I shelled a carload of the corn and shipped it to 
Chicago market where it graded No. 4. 
Shelby County. Illinois: Hereafter I will plant only Hy¬ 
brid, because it stands up better, yields more and ma¬ 
tures evenly, nice sound corn and no barren stalks. 
Carroll County. Missouri: The Hybrid Corn we got from 
you was satisfactory. It made about 60 bu. per acre. 
The stand was extra good. It made about 10 bu. per 
acre more than some open-pollinated corn I had. 
Ear shoot bagged before silks emerge 
to protect silks from all pollen. This is 
the first step in control breeding of 
corn. 
Tassels bagged to collect “Pure Pollen” 
(for selfing or crossing). Dusting the 
“Pure Pollen” on previously protected 
silks results in seed of known parentage 
and pedigree. 
After “Pure Pollen” of known origin 
is dusted on the protected silks, the 
ears are covered with large bags fast¬ 
ened securely in place as a protection 
against contamination from unknown 
pollen. Seed produced on these ears is 
of known parentage and pedigree.
