Natural enrichment of selenium in Saskatchewan field peas (<i>Pisum sativum</i> L.).
Bibliographic record
Abstract
Pulses are important dietary sources of selenium (Se). Supplying needed Se through widely used foods such as pulses and cereals could increase dietary Se intake. We analyzed the total Se concentration of 17 field pea (Pisum sativum L.) cultivars grown at six locations for 2 yr in Saskatchewan. A significant effect of location was identified, with the highest Se concentration in pea seeds grown in the Saskatoon region and the lowest concentration in the Melfort region. The effect of crop year was not significant. Significant genotypic differences in total Se concentration among the 17 field pea cultivars were not observed in the combined analysis. Total Se concentrations over six locations × 2 yr ranged from 373 to 519 µg kg-1, corresponding to 68-94% of the recommended daily allowance (RDA) for adults based on a 100 g serving of dry field peas. Saskatchewan soils are derived from marine shale and are rich in Se, and pulses grown in Saskatchewan have the potential to provide an excellent natural source of this element. Key words: Selenium, field pea, biofortification

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.
