Just as the methods and machinery for handling and 
grading corn have been constantly improved, so have 
the best traits of the 187 Hybrids been isolated and 
strengthened. In the extensive research program that 
Lester Pfister has carried on for more than 27 years 
the guiding thought has been to let ‘‘the weaklings 
die.’’ Many thousands of inbred plants have been 
tested and rejected, hundreds of crosses were turned 
down as “‘not good enough,”’ until finally, the 187 
Hybrids emerged as the dependable seed with a 
record of good performance under adverse conditions 
and better performance under favorable circum- 
stances.
