I posted this two days ago and got no replies maybe it was the title
so I've put a new title. So can any body offer advice?

I have read somewhere that Pumpkin seeds taken from a pumpkin
generally dont breed true. I am asking this as I saved some seeds from
one last year and have grown two plants which are doing well. Now on
them I have growing things that are almost round but are green and
stripped like marrows in fact a better description would be to call
them stubby marrows as the stalk enters them from the side not the
top. Will these become orange pumpkins or will they remain stubby
marrows, also if they will become pumpkins do I need to turn them so
the stalk enters from the top?
