Chateau Stripmine compiles many publications without recording which one each line comes from, so its agreement counts for less than an independent genebank.

Species ancestry
Hubbard's ancestry is traced back to wild species for about 81%; the rest is unknown.
- V. vinifera38%
- V. labrusca44%
- Father unknown (open-pollinated)19%
How certain is the whole lineage?Covers every generation back to wild species, not just the parents: each part of the lineage counts its weakest link.Includes a one-source link: Traced through at least one link given by a single source.Father unknown (open-pollinated): Reaches a seedling whose father is unknown (open-pollinated).
Following every line of Hubbard's ancestry back to wild species: about 81% relies on a single source somewhere; about 19% can't be traced (unknown parent or open-pollinated).
