Seeds saved from hybrid vegetables grow true to the parent plant.
Contested
Seeds from a hybrid won't grow true to the parent. An F1 hybrid's seed scatters the traits — you get a mixed, often weaker crop, not a copy. If you want to save seed that comes true, grow open-pollinated or heirloom varieties; saving hybrid seed is a fun experiment, not a way to keep a variety.
What is actually known
You can save and grow seed from an F1 hybrid — the kernel of truth — but it does not come true. An F1 hybrid is the first cross of two distinct parent lines, and its seed (the F2 generation) segregates: the offspring are a genetic lottery, a mix of the grandparents' traits, often less vigorous and rarely matching the plant you saved from. Open-pollinated and heirloom varieties are the ones that come true, because they are stabilised over generations to breed true. So save seed from open-pollinated varieties if you want next year's plants to match; from an F1 hybrid, expect variety, not a copy.

what this rests on - one pointer
F1 hybrid seed segregates in the F2 generation so offspring do not come true and are often less vigorous; open-pollinated/heirloom varieties breed true; standard plant-genetics and seed-saving consensus
