    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.Includes a disputed link: Traced through at least one link the sources disagree on.Father unknown (open-pollinated): Reaches a seedling whose father is unknown (open-pollinated).

    Following every line of ES 643's ancestry back to wild species: about 72% relies on a single source somewhere; about 25% passes through a link the sources disagree on; about 3% can't be traced (unknown parent or open-pollinated).
