In agriculture and gardening, *hybrid seed* is seed produced by
cross-pollinated plants. Hybrid seed production is predominant in
agriculture and home gardening. It is one of the main contributors to the
dramatic rise in agricultural output during the last half of the 20th
century.^[1] The alternatives to hybridization are open pollination and
clonal propagation.^[2]

All of the hybrid seeds planted by the farmer will produce similar plants
while the seeds of the next generation from those hybrids will not
consistently have the desired characteristics. Controlled hybrids provide
very uniform characteristics because they are produced by crossing two
inbred strains. Elite inbred strains are used that express well-documented
and consistent phenotypes (such as high crop yield) that are relatively
good for inbred plants.^[2]

Hybrids are chosen to improve the characteristics of the resulting plants,
such as better yield, greater uniformity, improved color, disease
resistance. An important factor is the heterosis or /combining ability/ of
the parent plants. Crossing any particular pair of inbred strains may or
may not result in superior offspring. The parent strains used are therefore
carefully chosen so as to achieve the uniformity that comes from the
uniformity of the parents, and the superior performance that comes from
heterosis.

*History[edit]*

In the US, experimental agriculture stations in the 1920s investigated the
hybrid crops, and by the 1930s farmers had widely adopted the first hybrid
maize.^[3]
