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
Clinton's ancestry is fully traced back to wild species.
- V. riparia50%
- V. labrusca50%
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.Sources agree all the way: Traced to wild species through links where sources agree (or DNA confirms).
Following every line of Clinton's ancestry back to wild species: about 100% rests on sources that agree (no DNA proof somewhere).

🧪 For breedersDNA markers: flower-sex and berry-color genotypes, SSR fingerprint
SSR fingerprint
SSR (microsatellite) markers are short repeated DNA stretches whose length varies between varieties. Their sizes identify a vine and test parentage: a true parent shares at least one allele with its offspring at every locus.
| Locus | Allele sizes (base pairs) |
|---|---|
| VRZAG62 | 188 / 190 |
| VRZAG79 | 245 / 259 |
| VVMD5 | 230 / 254 |
| VVMD7 | 243 / 251 |
| VVMD25 | 237 / 249 |
| VVMD27 | 186 / 210 |
| VVMD28 | 240 / 244 |
