Abstract
The loss-of-function of betaine aldehyde dehydrogenase 2 (BADH2) in rice leading to the accumulation of 2-acetyl-1-pyrrolidine (2AP), the substrate of enzymatic reaction , makes the rice flavor. The rice aroma allele BADH2-E2 has been widely used in aroma rice breeding in China. In this study, a PCR/LDR-based functional molecular marker was developed according to the 7bp deletion in the second exon of badH2-E2 aroma allele. Using PCR/LDR-based markers, the genotypes of Shenfan24, Shenfan26 and their F1 hybrids in the badH2-E2 locus could be accurately identified, and screening the F2 population derived from the cross of Shenfan24 and Shenfan26 shows that the segregation ratio of badH2-E2 positive homozygous, heterozygous and badH2-E2 negative homozygous were 1:2:1. The results of this study provide a new type of molecular marker for marker-assisted breeding and have certain application potential.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
