Abstract
ABSTRACT Wild lentil genotypes are a valuable resource for genetic diversity, but their scientific study and utilization in breeding programs have been hampered by traits such as crossability barriers and seed dormancy. To make wild lentil genotypes more accessible for further exploration, we investigated the effect of different seed scarification techniques plus the abscisic acid (ABA) analog, ABA‐1019 on breaking dormancy and seed germination release in seven lentil genotypes and 54 accessions (lines). Dormancy was alleviated by scarification with or without the addition of chemical substances but germination release was dependent on lentil genotypes/accessions and seed coat manipulations. ABA‐1019 functions as an antagonist to native ABA, thereby blocking the ABA‐induced delay in germination. ABA‐1019 significantly increased germination and seedling emergence rates compared to the water and dimethyl sulfoxide (DMSO) controls. DMSO increased germination rates and indices in some lentil genotypes compared to water control. ABA‐1019 also had a positive effect on shortening the time to germination, emergence, and flowering, which is of particular interest when developing inbred populations or advancing lines to increase homogeneity. Our results indicate that combinational (physical and physiological) dormancy exist in some lentil accessions.

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
