SYSTEM OF 
AND BREEDING 
This work is done by a select 
group of experienced workers 
under expert supervision, and 
Landreths’ specifications. 
Drying Seed from Staked Plants 
Each cheesecloth bag contains seed from an individual plant selection 
carefully tagged. The seed from each plant selection is kept in a 
separate seed envelope properly marked. 
Stock Seed Drying 
The fruits from the best tested plant selections are used for stock seed, 
squeezed in barrels, fermented, then washed and dried on screens. 
Selling and Crossing 
The work of the tomato plant 
breeder is never finished. 
New varieties and better 
strains must be created. 
Landreths’ Assistant Plant 
Breeders are shown crossing 
tomatoes.
