Morphological Study on Elymus dahuricus, Hordeum brevisubulatum and Their F_1Hybrid and BC_1.
Bibliographic record
Abstract
The morphological characteristics of Elymus dahuricus, Hordeum brevisubulatum and their F 1 hybrid and BC 1 were observed. The results showed that the morphological characteristics of F 1 hybrid tended toward maternal E. dahuricus, the spike length of F 1 hybrid exceeded that of E.dahhuricus, and the spikelet length, florets per spikelet, the length of glume and lemma of F 1 hybrid also exceeded the average of parents, which showed the strong heterosis, F 1 hybrid inherited the characteristics of short rhizome and 3 spikelets per node from H.brevisubulatum, there was not significant effect on other characteristics; the characteristics of first backcross generation (BC 1) tended toward recurrent parent H.brevisubulatum,there were significant differences among lines; the shape of the first glume can be the characteristic trait for parents and their hybrids,which can be used as one of the most important characteristics to indentify genuine hybrid.

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.
