Relating to that science unit I am trying to put together. Does anyone have a list of recognized pumpkin traits and a list of dominant and recessive traits in pumpkins? This would be hopeful for my students when they are trying to make decision about seeds to germinate and cross.

I wish it was that easy. I dont think that there was ever a controlled study done to find the dominant and recessive genes. If we knew these traits, there would be a lot more big pumpkins with nice shapes.

Currently, I'm involved in a long-term study of GP/GS. Since this crop is not of great economic value, and takes a lot of growing, very few scientists are interested.

Here's a list of traits that have been studied in C.maxima: If it's in capital letters - it's considered dominant. If it's in lower-case - it's considered rec.

B - yellow ovaries, also causes lack of chlorophill production in stems and vines.
B-2 - bicolor
bi - bitter fruit
Bu - bush habit
D - dark stem
Fr - Fruit fly resistance
gl - glaborous, lacking trichomes
grl - grey leaf
Hi - hard rind inhibitor
l-1 - light fruit coloration
l-2 - light fruit coloration
lo-1 - lobed leaves
M - mottled leaves
ms-1 - male sterile
ms-3 - male sterile
Rd (or Rs) - red skin
s-1 - male & female sterile
uml - umbrella-like leaves
W - weak fruit coloration
wc - white corolla
Wmv - watermelon mosaic virus resistance
wyc - white-yellow corolla
yg - yellow-green leaves and stems
