Hybrid corn, unlike their inbred
parents, are vigorous, uniform, and productive due
to heterosis.

A number
of hybrid corn seed production systems are used to ensure
hybridization by forced
pollination between the female and male parental corn
lines.
Artificial emasculation (detassling)
and male sterility genetic-based systems are currently
the most poplar. Detasseling involves
the physical removal of the tassel from the female plant,
either manually or in combination with mechanical devices.
The detasseling is
probably the most difficult to manage of any of the
steps in hybrid corn seed production (Wych, 1988) because
the time period is so short. |
