Registration of durum wheat germplasm A0709‐BX05 with resistance to ergot
Bibliographic record
Abstract
Abstract A0709‐BX05 (Reg. no. GP‐1060, PI 698311) is a Canada western amber durum (CWAD) derived durum wheat [Triticum turgidum L. subsp. durum (Desf.) Husn.] line developed at the Swift Current Research and Development Centre, Agriculture and Agri‐Food Canada. A0709‐BX05 was selected by a modified pedigree breeding procedure from the single cross of A0262&AM050/‘Strongfield’ made in 2007. A0709‐BX05 was evaluated for ergot resistance based on the honeydew and sclerotial production on spikes in greenhouse testing from 2012 to 2018. A0709‐BX05 expresses a highly resistant response to ergot, with rare to no honeydew and very few to no sclerotia formed on the spike after inoculation, far superior to checks Strongfield, ‘AC Navigator’, and ‘AC Melita’ and better than ‘Eurostar’. A0709‐BX05 has a good package of agronomic, disease, and end‐use quality traits for the CWAD wheat class combined with the ergot resistance. The release of A0709‐BX05 will accelerate the deployment of ergot resistance in durum wheat breeding and genetic and genomic studies related to ergot resistance in durum wheat.

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.
