CROSSING CORN
By John Belling
Experiments in crossing corn have been continued at the Experiment
Station for the last three years. Some of the results may be of use to
corn-breeders.
Object of Crossing
Many of the varieties of corn best adapted to their localities have been
bred from crosses. To get a new variety of corn for a new locality, the
best way often is to make a cross. The first generation of the cross is fairly
uniform; but in the second year many different strains appear, and selec-
tions can be made of those which do best in the locality. Thus for south
or central Florida we might cross the white or the yellow Cuban corn (which
latter is extensively grown in the West Indies) with the Blltch corn of
Marion county, which is one of the best-bred Florida corns; or with the Mosby
corn of Alabama (which came originally from a cross); or with the Whelchel
corn of Georgia (also from a cross).
Method of Crossing
The usual way to cross corn is to put a row or two of one variety in
a field of the other, planting it a few days earlier or later if necessary, so
that they may tassel together. Before tasseling, all the young tassels on
the row of the one variety are to be pulled out. If this is thoroughly
done, every grain of this variety will be crossed. If a white corn is crossed
by a dark yellow (like the yellow Cuban), the crossed ears will be light
yellow. If a yellow Cuban ear is crossed by a white corn, the grains will
be lighter yellow than if their own pollen had been used. If a sweet corn
is crossed by any field corn, all the crossed grains will be smooth and
starchy, not wrinkled and sweet. If a flinty ear is crossed by a dent, it
remains flinty; and if a dent is crossed by a flint, it remains dent. If
white field corn is crossed by white sweet corn the grains do not change.

Some feeders take care of the crop by erecting racks under a shed or
cover of some kind, apd stacking the cane in an upright position against these
racks. This is as good a method as any, if care is taken to have all the butts
touching the earthen floor.
WINDROWING
Another method of preserving the crop, and one to be recommended, is
to lay the canes in windows when the first cold weather threatens. The cut
canes are laid in a long bed as is done when keeping seed-cane, but care must
be exercised that the layers are properly lapped, the foliage of one layer cov-
ering the caner of the preceding one. This bed can' be made much thicker
than a bed for seed-cane, and will preserve the cane in a normal condition un-
til it is wanted for feeding. It is not necessary to cover the bed with soil, as
in the case of a seed-bed. A good covering of trash, decaying cane leaves,
hay, or anything else available, will be sufficient.
SHOCKING
Another method is to put the cut cane in large shocks in the field, as when
shocking corn, making sure that the shocks are well tied up towards the top
with either strong twine or wire, so as not, to be blown down in windy
weather. When severe freezing occurs however, the outside of these shocks
is mnch injured, and considerable loss ensues.
