Inheritance of hull pubescence and seed color in annual canarygrass
Bibliographic record
Abstract
The availability of glabrous-hulled annual canarygrass (Phalaris canariensis L.) cultivars with yellow seed color may pave the way for developing this species into a food crop. The objective of this research was to study the inheritance of hull pubescence and seed color in annual canarygrass. A gametocide was applied to plants at Zadoks Growth Stage 42 to induce male sterility. CDC Maria, a glabrous-hulled and brown-seeded cultivar, was crossed with six pubescent-hulled, brownseeded annual canarygrass accessions and with CY193, a pubescent-hulled and yellow-seeded breeding line. In mono-hybrid crosses, segregation ratios of F2 populations were not significantly different from the phenotypic ratios of 3 pubescent-hulled: 1 glabrous-hulled for hull pubescence and 3 brown seeded: 1 yellow seeded for seed color. In the di-hybrid cross, a phenotypic ratio of 9 pubescent-hulled/brown seeded: 3 pubescent-hulled/yellow seeded: 3 glabrous-hulled/brown seeded: 1 glabrous-hulled/yellow seeded was observed. Glabrous-hulled and yellow seeded traits are each controlled by single recessive genes that segregate independently in annual canarygrass. Key words: Phalaris canariensis, canaryseed, inheritance, hull pubescence, seed color

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.
