Abstract
Abstract Gene flow from acetolactate synthase‐resistant ( HR ) B rassica juncea oilseed canola to related weed, S inapis arvensis (density 1 plant/m 2 ) was assessed in a 100 m 2 field plot of HR B . juncea . Two HR F 1 hybrids (H1 and H2) were detected among 109 951 seedlings screened with imazethapyr (hybridization frequency – 1.8 × 10 −5 ). Hybridity was confirmed using flow cytometry, B . juncea ‐specific amplified fragment length polymorphisms ( AFLP s) markers, genomic in situ hybridization ( GISH ) and PCR ‐based detection of B . juncea's HR gene. H1 and H2 had 2n = 27 and 2n = 45 chromosomes, corresponding 3x (Sr AB ) and 5x (Sr AABB ) genomic structures and reduced male fertility, 3.2 and 16.6% pollen viability, respectively. H1 was self‐incompatible, whereas H 2 set seed when selfed ( B . juncea trait). Selfed F 2 , F 3 and F 4 plants showed HR trait persistence and vigorous growth and high (80–100%) pollen fertility in 22% and 39% of the F 2 and F 3 plants, respectively. No progeny were obtained from F 1, F 2 or F 3 hybrids × S . arvensis backcrosses, suggesting the likelihood of introgression of traits is low to negligible.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
