A detasselling crew. 
Over 500 men divided 
into small units, 
under the direction 
of^an experienced 
supervisor, detasseled 
Funk’s fields in 1937 
to produce your 1938 
Funk High-Yielding 
Hybrid Seed Corn. 
Looking down rows of detasseled field. Funk Hy¬ 
brids are all first generation crosses. Control 
breeding on a large scale accomplished by plant¬ 
ing two unrelated strains of corn in a field in a 
systematic manner. All tassels of one (female 
parent) are removed before pollen is shed. The 
other unrelated strain (male parent) is only 
source of pollen in field. First generation Funk 
Hybrid is selected only from detasseled plants. 
PRODUCING 
FUNK HYBRID 
FOR YOU 
Large acreages properly isolated from other corn are planted with two 
unrelated pure foundation single crosses from the isolation plots to produce 
Funk High-Yielding Hybrid Seed Corn for you. These are planted in a sys¬ 
tematic way so that all the tassels can be removed from one foundation 
single cross before any pollen is shed in order that breeding may be as 
closely controlled in these large fields as it was during the earlier stages 
of the program. 
Lost season over 500 men were used in the Funk Production Fields re¬ 
moving tassels. These men were divided into workable small units with 
each group continually checked by an experienced supervisor. The work 
of the supervisor was checked each day by an experienced plant breeder. 
Tassels must be removed from the seed parent strain before pollen is shed 
regardless of expense. It has taken years to build up an experienced or¬ 
ganization to properly meet each “Major Operation" so that you get “The 
Best Hybrid First From Funk."
