I didn't know about hybrid seeds: "In agriculture and gardening, hybrid seed is produced by deliberately cross-pollinated plants which are genetically diverse" https://en.wikipedia.org/wiki/Hybrid_seed
They're also a huge pain in the ass to produce, at least in my experience. Producing hybrid corn seeds, for instance, is done by planting the two varieties in the same field, with one combine-width of rows of variety A alternating with rows of variety B. Then you need to wait until variety A is grown and ready to tassel, and de-tassel it before those tassels fully form and release the pollen that drifts onto the corn…
The de-tasseling is mostly automated these days with a sprayer attachment chopping off the tops and the legions of kids coming behind to get the ones missed.
Then they come along with another specialized attachment to ‘destroy’ the males. Basically just chop them up and leave in the rows which later on gets eaten by the cows. The outside border rows of males gets harvested and turned into winter feed for the cows.
Eventually the remaining corn gets harvested by a crew hired by the seed company because they want the full heads of corn to do their evil deeds to.
Fascinating stuff this modern farming.
