If you plant the seeds produced from hybrids, your results will not be good. I don't doubt that, in most cases. But at some point in evolution there must be discontinuities in chromosome count. If these are always absolute barriers to reproduction, there is a problem.

Let's say you had an insect whose chromosomes got "stuck". It produced 1000 eggs. All of a sudden you would have a new species with a thousand individuals.
