WHY does Lester Pfister produce his own Inbred and 
Foundation Seed? 
In 29 years of breeding corn, Lester Pfister has 
amassed a vast amount of information on the corn 
plant. He recognizes the difference between the 
strong and the weak plant, he knows which inbred 
to save and which one to throw away, he knows 
how the seed must be handled and what records 
must be kept — and only through the application of 
his knowledge can he be sure of the quality of the 
seed that he is offering for sale. 
WHY are hybrids produced by Lester Pfister called 
The 187 Hybrids? 
Because all of the hybrids bearing that trademark 
contain the hereditary traits of the famous Inbred 
187 which was developed many years ago by Lester 
Pfister. He has continued to maintain it in its pure 
state through the years, just as he maintains the pure 
lines of all his inbreds. 
WHY are all Pfister seed fields within 10 miles of 
El Paso? 
The seed fields must be close enough to permit easy 
traveling of men and machines, because all planting, 
cultivating, spraying, detasseling, and harvesting is 
done by trained personnel under the personal super- 
vision of Lester Pfister.

WHY do Pfister company employees do all of the 
work in the Seed Fields? 
In order to maintain Quality Control. In planting, 
the seed line and the pollinator rows must be spaced 
just right; in spraying, the timing is important be- 
cause of the hatching of the insects; in harvesting, 
the ears must be ripe and the kernels contain just the 
right amount of moisture. The timing of detasseling 
is extremely important. For example, a field will be 
unfit for seed if the pollen from the seed-producing 
rows is allowed to fall on the silks. This would not 
affect the appearance of the kernels, but it would 
affect the field of corn that the farmer grows the 
next year. For these (and other) reasons, trained 
company employees must perform the duties of pro- 
ducing the 187 Hybrids — for quality control can 
be had no other way. 
WHY is quality control needed? 
Controlled Quality in 187 Hybrids means maintain- 
ing individual characteristics in each of the hybrids, 
season after season; maintaining the high standards 
of grading and germination; and even providing 
ample supplies of seed in the grade sizes that most 
farmers want. In short, Controlled Quality means 
fulfilling our obligation to the farmers who plant 
187 Hybrids to provide a supply of seed on which 
they may depend season after season after season.
