Symbolic of the care and precision exercised in field testing and evaluating strains is this 
photograph of pea trials on one of our Twin Falls, Idaho, breeding farms. New varieties 
are originated and tested. Each lot and each strain of existing varieties is tested and 
evaluated. Many thousands of test plots are grown and observations recorded annually 
in the West and at Keystone Valley Farm near St. Louis. This work proceeds ceaselessly 
so that you as a user of Keystone seeds may be sure of the best. a 
Symbolic of the more than 100 years of continuous seed service to agriculture by our 
company and its immediate predecessors is the Keystone emblem which stands as your 
protection and assurance of supreme quality and value.
