LANDRETHS’ PENNSYLVANIA CERTIFIED PEPPER SEED 
A PROLIFIC PLANT 
The First in the World 
LANDRETHS’ PLANT-SELECT VERSUS FRUIT-SELECT SEED 
Most pepper selection is done from the 
basket rather than the plant. This is a 
great error since the plant is the unit of 
selection, not the individual fruits. When 
we started our new pepper improvement 
program in 1930, we began with the plant, 
selecting many thousands for testing the 
following year. 
In the subsequent years, we selected and 
tested the best plants each year until we 
finally obtained uniformity of plants and 
fruit, thickness of flesh, hollow crowns and 
increased yields per acre. 
In 1936, the Pennsylvania Department 
of Agriculture approved our work by issuing 
to us the first certification certificates ever 
issued in the United States. A distinct 
honor, and we appreciate it. 
OUR CERTIFIED PEPPERS ARE UNIFORM
