It really is a myth that seeds from hybrids will not grow successfully. It is pushed by purveyors of hybrid varieties as a way to help maintain their market share and then spread along by people who don't have sufficient experience with the biology to know any different.

In some crops, like corn, there are intense losses to production in later generations if extreme care isn't taken in how the seeds are selected for saving. In other crops, like tomatoes or squash, there is generally no loss apparent.
