Abstract

fetched live from OpenAlex

Abstract A sulphonylurea herbicide, tribenuron‐methyl, methyl 2‐[[[[(4‐methoxy‐6‐methyl‐1,3,5‐triazin‐2‐yl) methylamino] carbonyl] amino] sulphonyl] benzoate, was used to induce male sterility in rapeseed. Application of 0.2 μ g tribenuron‐methyl per plant at the bolting stage with the longest floral bud &lt;2 mm and repeated 15 days afterwards, resulted in 94.5–100% plants being male sterile in six different breeding lines, but combined with low phytotoxicity. However, excessive double application of the chemical (&gt;0.2 μ g per plant) did have some significant impact on rapeseed, including stunting, fading leaves and petals, reduction in the size of floral parts and a shortened duration of flowering. The percentage of hybrid seeds from ‘84004‘ treated with 0.2 μ g × 2 tribenuron‐methyl per plant and pollinated by a male parent ‘Huaye’ was 92.7%, which met the hybridity requirement in China. The results suggest that tribenuron‐methyl could be used as an efficient chemical hybridizing agent.

Teacher imitation

Not 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.
