I think what you are referring to are crop plants that have been genetically
engineered to have a "terminator" gene which renders the seed sterile at the
end of development. This guarantees that new seed must be purchased each year.
Seed cannot be held-over for the next year. For more information, search the
web for "terminator gene".
