LANDRETHS’ PENNSYLVANIA CROWN PICKED 
CERTIFIED AND CERTIFIED TOMATO SEED 
A PRODUCT OF SCIENTIFIC SELECTION 
All growers who purchase seed expect and should obtain good crops from that 
seed. Good Crops can be produced only by the use of Good Seed. By Good Seed 
we mean: 
First—Seed which will produce a crop true to type for the variety it represents. 
Second—Seed which will produce high yields per acre. 
Third—Seed free from disease. 
Fourth—Seed of high vitality, that is, quick germinating qualities and the 
power to make rapid and vigorous growth. 
LANDRETHS’ PENNSYLVANIA CERTIFIED TOMATO SEEDS 
ARE GOOD SEEDS —“SEEDS WHICH SUCCEED” 
Fruit Selected for Stock Seed 
Fruit Selected From the Best Plants for Stock Seed. The plant is the basis of 
selection. The plants are approved first, then stock seed picked from the best plants. 
THE LANDRETH SYSTEM OF TOMATO IMPROVEMENT 
The beginning of any Scientific Selection must start with the Plant. The saving 
of perfect fruits for stock seed without consideration of the plants from which those 
fruits came is generally very disappointing. The crop produced from those perfect 
fruits may be very inferior. The above illustration is typical of Landreths’ plant 
selected fruit.
