For anyone wanting to continue the squash x pumpkin hybridization here are my dream crosses for 2019:

2118* Jutras 2017 x 2138 Ceja 2018 or vice versa
And/Or
1807* Holub 2017 x 2138 Ceja 2018 or vice versa

I like the nice solid salmon color of the 2138 as a breeder.

The 2020 offspring will be pumpkins, but self them and in 2021 we'll be back to 1/4 greenies.

Good Luck Squash Growers!

Dreaming about a couple here also

2118* Jutras 2017 x 2152 D.Gantner 2018
and
2118* Jutras 2017 x 2469 Daletas 2018

Along with a couple crosses for 1/4 green producers in 2020

760 Cantrell (1844.5* Holub 16 x 2075 Connoly 16)
256 Cantrell (1585.5 Werner 14 x 1844.5* Holub 16)
Will most likely self both

This year I'll try to grow green pumpkin from my 1645.8 Dabrowski 2018 pumpkin seeds (cross between 2296 Paton and 1445 * Jutras).

mdab - The seeds from your 1645 will probably throw a pumpkin this year, but self it, or cross it with a squash and you'll have a chance and getting a huge greenie in 2020.

also see this thred for more on why this happens:

Thanks for the tip Scott. I will self/sibb it this year and I'll continue this 'project' in 2020.

Arent some greenies carrying recessive white? I would try a greenie but which ones currently available dont have any hidden white genes? I wonder if a strong vibrant orange like the gantner would lessen the chance of white genes hiding?

The gene that hides... Would it be fair to say its a more translucent white than a solid paper white?
G-green
w-white
o-no white
p-pumpkin colors

ggww=white shows
ggwo=green
ggoo=true green
ppww x ggoo =
pgwo

pgwo x self =
ppww
ppoo
pgww
pgwo
pgoo
ggww
ggwo
ggoo

ppoo x ggoo

would be best but hard to identify 3/4 of all pumpkins are carrying recessive white. Thats as simple as I can figure it.

It may be more complicated than this, p representing all pumpkin colors of true pumpkin lines simplifies it... not sure if the probable squash outcomes are correct for every possible configuration of genes that p might represent.

I made an error
p should be P
G should be g
because pumpkin colors completely dominate.
True pumpkin with expressed opaque gene x true green:
PPww x ggoo=
Pgwo

resulting gene possibilities when selfed:
PPww same as grandparent 1/16 chance
PPwo pumpkin 1/8 chance
PPoo possible super nice orange depending on the many genes that PP represents? 1/16 chance
Pgoo pumpkin 1/8
Pgow pumpkin1/4
Pgww pumpkin probably ugly 1/8
ggoo squash true green 1/16 chance
ggwo green squash, carrying recessive w gene 1/8 chance
ggww not a squash and never going to be a true pumpkin either...translucent white also 1/16 chance
Anyhow please comment if you think this checks out in terms of what we have seen in the past and maybe we can improve the odds in our favor by finding a PPoo type pumpkin to start with. Hard to tell which have recessive white ironically a big white pumpkin like the 2157 Daletas could possibly not have the recessive white gene? I dont know what salmon color indicates but the recessive white should be identifiable if we knew what to look for. Even though its recessive there should be some slight indication.
Perhaps there is no recessive white gene perhaps there is another genetic mechanism but one way or another the genetics are not staying green 100 % of the time. Interesting project certainly.

G. Kins Are you calling dark orange "P" ?

What is "o" "no white" gene?

There is a recessive white, but not all whites are "ww"

And having one "w" gene has no effect on a fruit's colour
