Interspecies squash hybrids
« on: 2019-09-28, 04:28:20 PM »
Spent some time looking at Josephs squash ID guide. http://garden.lofthouse.com/how-to-identify-squash.phtml

This year I grew intentionally maxima squash, pepo squash, moschata squash and two interspecies hybrids from Joseph Mospermia and Maximoss. Though I used much of my maximoss seed last year, a few grew again this year, possibly because I mixed some in with the mospermia last year then never got it planted and last year's grew at least well enough to contaminate my maxima a little.

I also grew a Thai cross moschata from Mike a hybrid Moschata from Territorial called Autumn's Choice, and a old land race called Rancho Marques. All with some moschata characteristics.

I think that the thai cross squash from Mike might be an example of ancient mospermia. Also the Rancho Marques but it didn't produce a fruit for me. Also the Autumn's choice I think may in fact be a more modern Mospermia type. It's leaves look maple like and the fruits have that interesting pattern of yellow and green bands.  My actual mospermia and maximoss look like they should. The Mospermia tend toward moschata peducles. I see one small squash that looks just like a tetsukabuto. Though mostly I think that my maxima grex has just a little maximoss contamination now. Which is fine. There is one mospermia fruit that looks like Autumn's choice.

I guess maximoss is a hybrid between maxima and moschata.

But what is mospermia?
