genus/species question

[ChristinaJo]

This is concerning squashes:

Usually, the genus can be the same, but as long as the species is different,it shouldn't cross.Right?
I use this rule for seed purity in the garden for other vegetables,but I'm confused about the squashes.....I've read confusing info....
Set me straight,you squash gurus!!!
Thanks 🙏

As the link states, cross pollination will not affect the shape or flavor of the current year's crop but I never save seeds from any squash because they cross pollinate so easily.

Some crops like corn will have their flavor changed by cross pollination because in the case of corn we are eating the part of the plant that will become the seeds. Sweet corn tends to lose it's sweetness when pollinated by other corn and if you live in a farming area then "field" corn pollen will be blowing around.

Someone here posted some time ago what squash would cross pollinate.

The commonly cultivated squashes are C. Pepo, C. Maxima, C. Moschata, and C. Mixta. They generally won't cross between species. An easy way to figure out which species a given variety is in is to look at Glenn Drowns' page. He lists species in the header followed by the variety name.

That was interesting about cross polinateld corn, ...we eat its seeds.
