Abstract
Fusarium head blight (FHB) challenges the malting and brewing industry due to the presence of the mycotoxin deoxynivalenol (DON) in infected grain. New barley ( Hordeum vulgare L.) cultivars must have improved resistance while still providing producers with robust, high yield. ‘Lowe’ (Reg. no. CV‐369, PI 689750; Canadian Food Inspection Agency Reg. no. 8132; Canadian PBR Cert. No. 5884) is a two‐rowed, hulled, spring barley developed for malting use, especially for the craft brewing industry. Lowe has a high level of resistance to FHB, accumulating 50% less DON than ‘AC Metcalfe’, with levels similar to the most‐resistant check, ‘Chevron’. Lowe was created using a modified bulk breeding method with the headrow that produced Lowe derived from a F 6 population. It was tested as TR13609 in trials managed by the Prairie Recommending Committee for Oat and Barley from 2013 to 2015. Lowe outyielded the malting checks AC Metcalfe and ‘CDC Copeland’ in 2 yr of agronomic evaluation. It is a tall cultivar with better lodging resistance than the malting checks. Lowe matures 3 d later than the malting checks. Lowe has excellent properties for malting and brewing, with low protein, high extract, and low β‐glucan concentrations in the wort. Lowe is resistant to surface‐borne and loose smuts and moderately resistant to scald, spot form of net blotch, and FHB. Lowe combines excellent agronomic, disease, and malting attributes suitable for all‐malt brewing that will make it suitable for production on the northern Great Plains.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
