Revised International Registry of Cultivars and Germplasm of the Genus<i>Amelanchier</i>
Bibliographic record
Abstract
An updated International Registry of the genus Amelanchier, consisting of 32 ornamental cultivars and 25 cultivars grown for fruit, was created on the basis of published information, unpublished research data, and observations made by originators or their successors. Additionally, in 1997 a survey of the location and availability of Amelanchier germplasm was sent to 60 botanical gardens and arboreta across Canada and throughout the central and northern United States. Thirty-three replies were received of which 31 of the gardens or arboreta had Amelanchier germplasm. The collection of Amelanchier at the University of Saskatchewan was included in the survey results. The survey indicated that various Amelanchier species and cultivars are widely distributed. A total of 25 different species, subspecies or varieties, 8 different hybrids, and 42 different cultivars were reported as being held in the collections surveyed. This study comprises the most recent, comprehensive and quantitatively characterised list of Amelanchier cultivars to date. This information will be beneficial to the nursery industry in terms of cultivar characterisation, the exchange of plant material, and the development and distribution of new Amelanchier cultivars.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
