Detasseling
（重定向自Detassel）
Detasseling corn is removing the pollen-producing flowers, the tassel, from the tops of corn (maize) plants and placing them on the ground. It is a form of pollination control, employed to cross-breed, or hybridize, two varieties of corn.
Fields of corn that will be detasseled are planted with two varieties of corn. Every corn plant has both male and female parts, so if both varieties of corn were left intact, some of the resulting seeds would have non-hybrid parents. Removing the tassels from all the plants of one variety leaves the grain that is growing on those plants to be fertilized by the tassels of the other, resulting in a hybrid.
