Analysis of dwarfing genes in Zhepi 1 and Aizao 3: Two dwarfing gene donors in barley breeding in China
Bibliographic record
Abstract
Inheritance of plant height was studied in Zhepi 1 and Aizao 3, two dwarfing gene donors used in barley (Hordeum vulgare L.) breeding programs in China. With direct cross and para-backcross methods, allelism tests were conducted for Zhepi 1 and Aizo 3 with barley entries carrying either brh 1, uzu 1, sdw1, or six new dwarfing genes recently identified in Chinese barley accessions. Plant height in both Zhepi 1 and Aizao 3 was controlled by the same recessive dwarfing gene. The dwarfing gene carried by both of these cultivars is different from the three known and the six new dwarfing genes. Based on the results of this study, only two dwarfing genes have predominantly been used in barley breeding in China since 1950. Key words: Hordeum vulgare, dwarf source, dwarfing gene

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.
