ISOLATION PLOTS 
The first step in the transition from the research program into Funk High 
Yielding Hybrid for farm use is the increase of seed stock of necessary foun¬ 
dation strains. This controlled breeding increase is accomplished by using 
plots so isolated that unknown pollen is not a factor. In a large corn grow¬ 
ing area, such plots are difficult to locate and manage. Here is a large ex¬ 
pense item in the production of Funk High Yielding Hybrid Corn. 
Some small isolated plots are devoted to increasing seed of inbred 
strains. Others are used to combine two inbred strains by crossing. Such 
crosses are known as Foundation Single Crosses. Experience has proven 
these plots to be a "Major Operation" in the production of Funk Hybrid 
Corn. 
Over 60 isolated plots were under Funk Management last season. There 
is a Funk High Yielding Hybrid adapted to every part of the Corn Belt, 
This means that many kinds and types of foundation seed are necessary 
in order to cover the wide range of maturity, soil and climatic conditions 
encountered. The timbered area at Funks Grove is a valuable asset in se¬ 
curing adequate isolation for Pure Foundation Seed which means again, 
"The Best Hybrid First From Funk." 
Lake County, lll’inoh: The seed corn I got from you last year was O. K. It made 90 
bushels per acre which is a very high yield for this corner of the state. 
Adams County, Illinois: In regard to the Hybrid Corn I purchased from you. will say 
I am very well pleased with the results. I picked 900 bu. of corn from 1 bu. of seed. I 
have a standing order for 5 bu. Hybrid with your company.
