to applying fungicides and fertilizers to
reach maximum yields. "
While first introduced in the 1910s,
hybrid technology for corn did not gain
momentum until the 1940s. The cumulative
impact over the last eight decades has
been extraordinary. Corn yields forecast
by the US Department of Agriculture
for the 2021 crop were 180 bus per acre,
up 475% from 1940 yields of 76. Over this
same period, wheat yields increased by
231%. More recently, since 1980, corn
yields are up 97%, versus 51% for wheat.
Over the last 40 years, corn acreage has
increased 8% while wheat acreage has
dropped 43%.
Why weren't wheat hybrids developed
and introduced alongside corn hybrids in
the 1940s? Stephen Baenziger, PhD, professor
emeritus of Agronomy at University
of Nebraska - Lincoln, identified two
principal reasons.
The first is that wheat already was
Stephen Baenziger
benefiting from successful breeding programs
in the 1930s and 1940s, and the need
to increase yields through hybridization
was not seen as compelling. By contrast,
for the 30 years before 1940, corn yields
were barely moving, Dr. Baenziger said.
Indeed, from the mid-1860s until a peak
are not as high as in Europe, " he said. " In
suboptimal growing areas I think hybrids
will really differentiate from conventional.
At the same time, you need growers
who are comfortable with high tech.
In Europe, growers are more receptive
in 1915, wheat yields jumped 52%. Peak
corn yields, reached in 1906, were up
about 30%.
" Productivity in corn was basically flat,
as opposed to wheat, which had continuous
improvements because we had a very
good dedicated breeding sector working
on that, " he said.
Private companies tried introducing
wheat hybrids from time to time over
the past century, but because cross-bred
wheat varieties were seeing modest
yield increases, the hybrids that were
introduced failed to adequately separate
themselves from conventional cultivars,
Dr. Baenziger said.
" The public program and private
programs continued to improve their
competitors, the cultivars, " he said. " And
the hybrids never really could distance
themselves from what was coming from
behind. "
Dr. Baenziger cited a second key reason
corn hybridization programs were more
successful than wheat.
" Hybrids were relatively easy to make
in corn, " he said. " It's much more difficult
in wheat. "
Produced by crossing two inbred lines,
hybrid grain requires the sterilization
of the male components of one of the two
parents, to prevent the plant from self fertilizing.
In the case of corn, sterilization
is relatively easy. Once it appears in the
field the tassel (male) is removed from the
plant, and the ear (female) is fertilized by
another plant. Multiple rows of detasseled
female plants grow beside single or double
rows of male plants, the pollen from
which fertilize the female plants, which
then generate the hybrid seed.
In the case of wheat, the male parts
