HYBRID CORN
By John Belling
It has been found that hybrid corn of the first generation of the cross
between certain different varieties of corn gives a larger crop than either of
its parents, or than its own offspring. In some cases it gives so much larger
a crop that it pays to raise hybrid seed in quantities every year. This first
generation Hybrid is often more vigorous than its parents, and usually com-
bines the good qualities of both parent varieties. In north and central
Florida, dent corns (such as Mosby Prolific and Blitch) are usually grown.
In south Florida, the West Indian or Cuban yellow flinty corn is more likely
to succeed. But by growing the 'hybrid generation between the Cuban and
one of these dent corns, we may get larger ears, sturdier plants, and a
greater yield.
Tests
In a comparative experiment this year, the hybrid seed-grain of 'Mosby
pollinated by Cuban gave more than one-third more shelled corn to the
row than did the pure Cuban or Mosby. The rows were grown alongside,
and the weights of shelled corn, for rows of sixty stalks each, were: Hybrid,
444 ounces; Cuban, 309 ounces; Mosby, 291 ounces. The Mosby was more
Sworm-eaten than either the Cuban or the Hybrid. Alongside was also planted
the grain from the Hybrid grown in 1911; that is, the second generation from
the cross. This only produced 345 ounces of shelled corn to the row of sixty
stalks. Thus the second generation does not give much more than the
original parents. Also the Hybrid stalks and ears of the first generation
were as uniform as the parents, while those of the second generation varied
greatly. These rows were 3 feet apart, and the stalks were 3 feet apart in
the rows. Georgia (Whelchel) corn, with rows 6 feet apart, gave 366 ounces
of shelled grain to the row of sixty stalks, while the first generation Hybrid
between Georgia and Cuban gave 478 ounces. These two first generation Hy-
brids had also been grown in 1911, along with the first generation Hybrid

between the Blitch and Cuban, and it was obvious then that all three gave
better plants, better ears, and a better yield than their parents.
The Cross
It is intended to repeat these tests on a larger scale in 1914, but from
the tests in 1911 and 1912 it is probable that anyone in central Florida, with
a sandy soil, making the cross between Cuban and either Mosby, Georgia,
or Blitch, would have an increased yield next year which would pay. The
cross is easy to make. One has only to plant alternate rows of Cuban and
one of the other three varieties, and at the time of tasseling go along the
rows, every other day for a week or so, and pull out all the young tassels of
one variety. Thus if one is growing Cuban corn, and desires to get hybrid
seed of Cuban and Blitch, for next year's crop, he would put in several
rows of Blitch alternating with the Cuban in the middle of his field, and
afterwards pull out all the young tassels of the Blitch. (The Blitch may be
planted a few days later than the Cuban.) The fact of the crossing having
taken place would be shown by all the grains on the Blitch ears being light
yellow. Next year, the field planted with this hybrid seed would probably
yield a heavier crop than the Cuban would have given. (Each ear of this
crop will show, on the average, 25 per cent. of the grains white, an equal
number dark yellow, and 50 per cent. light yellow.) The seeds of this first
generation hybrid should not be planted, as the yield decreases in the second
year; but the cross, if favorable, should be made again each year in a sepa-
rate seed-plot, with alternate rows of the flint and dent parents, by detassel-
ing one of them.
I Hybrid Seed-corn
This method will appeal chiefly to farmers who grow seed-corn for sale;
and different kinds of hybrid seed-corn of the first generation will possibly
soon be on sale in most of the States of the Union, at a higher price than
pure corn, because of the increased yield. In the cross of the Cuban by one
of the three dent corns, we probably have a combination suited to those who
grow corn for feed, in sandy soil, in central, and possibly in south, Florida.
