Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent identify pumpkins and their cultivars, explain cultivation, nutrition and uses, relay food and agricultural information from reliable sources, and separate pumpkins from other squashes and gourds by usage rather than a strict botanical line.

The large round fruit of certain cultivars of squash, mainly Cucurbita pepo, Cucurbita maxima and Cucurbita moschata, with a hard rind, usually orange, and seeds in a central cavity; grown for food, seeds and oil, for decoration and carving at Halloween, and for giant specimen competitions, with names and cultivars varying by region.

What it is for: Food, seeds, oil, decoration and competition.

It can be identify cultivars and species; explain cultivation and storage; relay nutrition and culinary uses; distinguish pumpkins from other squashes.

Hard-rinded squash fruit

Orange flesh rich in carotenoids

Cultivars across several species

Cultural role at Halloween and harvest

What it looks like

A large round or oblong fruit with a ribbed hard rind, usually orange but also green, grey or white, with a thick stem.

Physical character

mass: 1-20 kg - typical; giant cultivars exceed 1000

growing season: 90-120 days

How it is recognised

Round hard-rinded squash fruit, usually orange

Cultivars of three Cucurbita species

Winter squashes and gourds overlap; the distinction is by usage and region

  • Should each species be a separate entry?
  • How should cultivar registers be linked?
  • The registry entry has merged aliases naming specific cultivars; should they be split off?
