Abstract

fetched live from OpenAlex

Protein quantity and quality are known to have an impact on nutritional value of barley ('Hordeum vulgare' L.) and end-use quality in wheat ('Triticum aestivum' L.). Fifteen genotypes of spring barley and thirteen genotypes of winter wheat from nine official Ontario Performance Trial locations across Ontario over four years were analyzed for protein and agronomic parameters. Analysis of variance revealed environmental main effect of barley genotypes for total protein, soluble, and insoluble fractions accounting for 35%, 34% and 32% of the total variation, respectively. The main effect of genotype of winter wheat was highly significant and accounted for 57%, 57%, and 52% of the total variation for total protein, soluble and insoluble fractions, respectively. The conclusions of the study were that an increase in total protein results from an increase in the insoluble fraction which leads to a reduced nutritional value of barley grain and a higher quality value of wheat grain for bread.

Not 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.
