watermelon
Let an agent identify watermelon and its cultivars, relay cultivation, nutrition and uses, describe origin and economic role, and distinguish watermelon from other melons.
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 watermelon and its cultivars, relay cultivation, nutrition and uses, describe origin and economic role, and distinguish watermelon from other melons.
An annual vine of the gourd family, Citrullus lanatus, cultivated for its large fruit with sweet, watery red, pink, yellow or orange flesh and a thick green rind, originating in Africa and grown worldwide in warm climates, with thousands of cultivars including seedless triploids and named varieties such as the Chinese 8424 and the Armenian Arevik; watermelon is eaten fresh, juiced and pickled, and China produces most of the world crop.
What it is for: Fresh fruit, juice and other foods.
It can be identify cultivars and types; relay cultivation and nutrition; describe origin and trade; distinguish from other melons.
