Evidence you can inspect

Counts are live database numbers, not marketing copy. Every one of them is a link you can follow to the records behind it.

510
Varieties, every claim sourced
62
Cited sources
5
Published trials. Trial coverage is still limited, and we show where it exists.
82
Individual trial observations, each tied to its method
357
Of 510 varieties have no independent corroborating reference

That last figure does not mean unsourced, and it does not mean wrong. Every record cites its sources; for these 357 the sources are all seed catalogs, community collections or trade press, with nothing from an institution or a journal independent of the seller to corroborate them. Frequently that is the only evidence in existence, because the breeder does the screening and publishes it in their own catalog. We publish the count rather than hide it.

Unknown stays unknown. A dash is never a guess.

The rules behind these are enforced by the build, not promised by a policy.

Counts are live database numbers, not marketing copy. Two crops are built out; the rest carry crop-level intelligence while their variety data is still being sourced.
