Abstract
Abstract Severities of the stem rusts of wheat and barley [Puccinia graminis f. sp. tritici] and oat [P. graminis f. sp. avenae] were light in Canada in 1998. Sixteen different pathotypes were identified from 151 P. g. tritici isolates, and 4 pathotypes were identified from 105 P. g. avenae isolates. The majority of P. g. tritici isolates from wheat were collected in Alberta and British Columbia, where the pathotype QFCSR made up 78% of the isolates. The majority of P. g. tritici isolates from barley were collected in Manitoba, where RCRSK made up 63% of the isolates. All P. g. tritici isolates were virulent to Sr5, Sr21, Sr9g, and Sr9d and avirulent to Sr22, Sr24, Sr25, Sr26, Sr27, Sr29, Sr30. Sr31, Sr32, Sr33, Sr37, and Sr40, a series of resistant lines, and commonly grown bread and durum wheat varieties. Most P. g. avenae isolates from both cultivated and wild oat were NA29. A pathotype new to western Canada, NA67, was identified that has combined virulence to Pgl3, Pg9, and Pg2. It constituted 15% of isolates from wild oat and 27% of isolates from cultivated oat and is virulent to the commonly grown oat cultivars in western Canada.

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
