Moschata x pepo for insect resistance?
« on: 2021-06-08, 09:25:03 PM »
I planted moschatas and pepos--the pepos are being eaten alive by the earwigs, the moschatas under exactly the same conditions (just a few feet apart) are being left alone.

I'm wondering what would happen if I crossed the moschata and pepo, then back-crossed into the pepo line. Possibility of keeping the insect resistance while reverting to the pepo?

Pepo seems to me like it's the furthest removed from other squash species. The few times that I have thought I might have an interspecies cross with pepo as a parent, the seeds didn't germinate, or the plants died without producing offspring. A few manual interspecies crosses that I have tried with pepo as a parent didn't set seeds.

That doesn't mean that it couldn't happen. Just that my particular varieties and methods didn't work in a particular growing season. Biology is fuzzy.

Chance started an interesting thread.

"Cucurbita lundelliana bridge"

This species has been used to move pepo - moschata - maxima - argyospermia traits together.



Most squash types don't readily cross outside of their species.

Moschata and Argyospermia/Mixta can apparently hybridize relatively easily, which would be an exception.

Like Joseph said, pepos are pretty far removed from the other domesticated types.


I would try looking for another pepo cultivar with noted insect resistances first, or trialing other pepos to see if they are eaten at as well.
