RESULTS 
S UPERIOR CORN BREEDING gives Pioneer Hi-Bred seed corn these 
characteristics—higher yield, stiff, sturdy stalks, heavy root system, 
strong shanks, large, sound ears, drought and disease resistance, uniformity, 
strong germination, and proper maturity. 
Pioneer Corn is noted for early maturity and high shelling percentage re¬ 
sulting from extremely small cobs and deep grains.

THE TYPICAL ROOT SYSTEM OF PIONEER HI-BRED CORN 
rpHE PIONEER HI-BRED CORN COMPANY was the first 
commercial producer of hybrid seed corn. It operates in 
the hybrid seed corn business exclusively. The hybrid business 
is not just a side line with the Pioneer Company. Pioneer does 
not contract with small inexperienced growers to produce 
Pioneer hybrid seed corn. 
It is little wonder Pioneer has the parent seed stocks to en¬ 
able them to produce the majority of the hybrid strains sold 
throughout the corn belt. Pioneer does not produce all of 
these hybrids. Our breeding department has made extensive 
tests and we concentrate our production on the corn we find to 
be the most practical for the corn grower to produce. Pioneer 
puts out a better bred, sorted, dried and graded hybrid 
seed corn.
