Origin of "terminator seeds"

[LoneBear]

I've been wondering something for a while... Monsanto sells millions of pounds of "terminator seeds" (plants with sterile seeds that will not sprout). Where are THEY getting all that terminator seed FROM, to sell to farmers? It has to be grown somewhere, right?

I'm starting to wonder if their level of genetic engineering is producing seeds right "out of the test tube." Manufactured seeds, rather than Nature's way.
