I thought the gpc rules were posted somewhere but I can’t find them now. Thank you... Concerned about the amount of “orange” that will be tolerable. I have two strains of zucchini both held well in the field but turned a little bit orange on the underside. I can just assume that without extra effort to keep this from happening... the same thing can happen to a marrow?

17. Marrow – Cucurbita pepo
For competition purposes, the following distinctions are made between marrows and zucchini (syn. courgette): A marrow is grown on a vining plant, a zucchini on a bush type plant without vines. A marrow generally has rough skin while a zucchini generally has smooth skin. A marrow is generally quite uniform in thickness while a zucchini tends to taper out towards the blossom end.
Specific rules:
a. The vine must be trimmed within 2.5 centimetres (1 inch) of the stem.
b. Marrows may be green with green or yellow striping or completely yellowish-white. No orange colouring is accepted.

So will they develop orange if left a long time ? My zucchinis dont have pumpkin genetics but they sat in the field long enough they did get some orange near the ground. If marrows can get orange similarly then how can I prevent this? Keep them off the ground? Are they ripe when they are done gaining size or should they be left on longer...Thanks.

I have yet to see the GPC rules for Marrow. Wouldn't surprise me if the GPC adapted the rules that Brad has posted. I don't get the "orange" rule. It's not like those crosses that produce limited orange are at some advantage over a non-orange fruit. I'm willing to bet that 90%+ of Marrows brought to GPC weight offs will not be true Marrow's as described by the rules that Brad mentions. But, this isn't supposed to be easy.....lol

Yeah the GPC needs to post clear rules up front.

Marrows should stay green for an awful long time. I have only seen them go orange when field pumpkins were bred into them (by accident). Field pumpkins have less chance of splitting.
The rules I posted were taken over by the GPC. I'm sure they will post them soon on their website.

Malvern is the biggest marrow weigh in in the world and the judges still allow marrows with orange in them on the bench. To be honest it doesn't bother me as like wexler said there's no real advantage although anything entered as a WR needs to be 100 % true marrow. Some of the best marrow growers in the world over here are still open pollinating which doesn't help.
