Abstract
Morphological, anatomical, physiological, and nutritional seed characteristics of the lablab bean (Lablab purpureus) were investigated in 46 germplasm accessions, from wild through semi-domesticated forms to landraces and current cultivars. This study aimed to improve the understanding of the domestication process in this tropical crop legume. Wild accessions were distinguished by typical small, brownish and mottled seeds. Cultivated and semi-domesticated forms showed much wider variation in size, colour and shape. Most wild accessions had a thicker seed testa as well as a greater spread of germination over time and larger proportions of hard seeds than most cultivated and semi-domesticated accessions, which germinated more uniformly. Generally, wild accessions showed higher tannin and nitrogen values. In most characteristics, semi-domesticated accessions were intermediate. Not all cultivated accessions combined all typical features of the ‘domestication syndrome’. This was particularly obvious in the dendrogram generated by cluster analysis from a relative domestication index calculated from seed mass and seed-coat texture for any pair of accessions. On the basis of seed characteristics of the germplasm studied, the crop is considered to have originated from Africa.

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
