It's the same as with most things. If the variety is an F1 Hybrid it
will revert to some of the parent characteristics. So those won't
"grow true" in the sense of exactly matching the variety chosen. But
they will be perfectly good courgettes nevertheless.

If not a hybrid variety, then they will probably grow pretty much as
the previous crop, depending on what pollinated the crop.
