HYBRID CORN 
In the last few years Corn Hybrids have made marked progress and are fast becom¬ 
ing popular with farmers. Adapted hybrids excell in yield per acre, are more re¬ 
sistant to disease, have more uniform stalks and ears, and are much more resistant 
to wind because of their superior root systems. Frederick D. Richey, chief, Bureau of 
Plant Industry, U. S. Department of Agriculture, in Farmers’ Bulletin No. 1744, gives 
a very simple description of hybrid corn by comparing it to the mule, as follows: 
“A corn hybrid, in fact, has many things in com¬ 
mon with the mule. A mule is the first-generation 
hybrid between the mare and the ass, and partakes 
of the better qualities of both parents. It does not 
reproduce, but must be produced anew each gen¬ 
eration for its value in itself, not for reproduction. 
A corn hybrid is the first-generation hybrid between 
two strains of corn. Its value is for seed in the pro¬ 
duction of a crop of commercial corn. This corn 
will grow, but cannot be used for seed without a 
loss in yield in the succeeding generations.” 
Various State Agricultural Experiment Stations and The U. S. D. A. Bureau of 
Plant Industry have pioneered in the development of adapted hybrids. In 1937 we 
plan to produce seed of a limited number of hybrids, which performance tests, con¬ 
ducted by the Ohio Agricultural Experiment Station and the Bureau of Plant In¬ 
dustry have shown to be adapted to specified districts. 
The hybrids which we offer will comply with both Federal and State regulations 
which specify that: 
“No person, firm, or corporation shall offer for sale or distribute within 
the State of Ohio for seeding purposes within this State, any seed of field, 
sweet, or pop corn labelled or represented to be “hybrid” corn unless such 
seed represents the first generation of a cross between strains of different 
parentage and involving one or more inbi’ed lines of corn or their com¬ 
binations.” 
Only the first generation of a hybrid between inbred lines or their combinations 
exhibits the maximum combination of desirable characters affecting strength of 
stalk, freedom from disease, absence of barren stalks, resistance to drouth, ability 
to yield, and quality of the harvested crop. Seed saved from a field planted with a 
corn hybrid will have 10% to 25% lower yielding ability than the first generation 
seed. Be sure, however, that the hybrid purchased is adapted to your climatic and 
soil conditions.
