Any ideas on how they are produced commercially?

IIRC, the inbred parent lines have at least the female parent with sterile
pollen, so only the _other_ parent can pollinate it and produce seed. I
believe some are still done by hand pollination; these are the really
pricey ones!
I haven't worried too much about all that, because I don't demand absolute
uniformity in the crop or harvest time, and I save my own seeds wherever I
can.


But if you really like a particular tomato say, and save some seeds from an F1
hybrid - surely the new plant will not be the true tomato which you like?
