I've continued working on adding diversity to my squash... Last year a couple of interspecies hybrids between mixta and moschata squash showed up.
Here's what one of them looked like:
F1: [mixta X moschata], also showing squash like the mixta and possible moschata parent.
This year I grew the hybrid seeds from that squash in an isolated patch. This is what a couple of the siblings from that fruit looked like. (Different daddies).
Looks to me like a classic moschata squash, so I'd guess that the genetics are, BC1: ([mixta X moschata] X moschata).
I'd guess the genetics of this squash are, F2: [Mixta X Moschata]. It's picked up the orange-fleshed trait from moschata.
This week I received seeds from a [maxima X moschata] hybrid. I'm looking forward to adding that to the mix next growing season.
