Abstract
Bambara groundnut ( Vigna subterranea (L.) Verdc.) is an important African legume crop. In this study, a collection consisting of 240 accessions was analyzed using 22 simple sequence repeat (SSR) markers. In total, 166 alleles were detected, with a mean of 7.59 alleles per locus. Allelic and gene diversities were higher in the west African and Cameroon/Nigeria regions with 6.68 and 6.18 alleles per locus, and 0.601 and 0.571, respectively. The genetic distance showed high similarity between west African and Cameroon/Nigeria accessions. Principal coordinate analyses and neighbor-joining analysis consistently revealed that the majority of west African accessions were grouped with Cameroon/Nigeria accessions, but they were differentiated from east African, central African, and southeast Asian accessions. Population structure analysis showed that two subpopulations existed, and most of the east African accessions were restricted to one subpopulation with some Cameroon/Nigeria accessions, whereas most of the west African accessions were associated with most of the Cameroon/Nigeria accessions in the other subpopulation. Comparison with SSR analysis of other Vigna cultigens, i.e., cultivated azuki bean ( Vigna angularis ) and mungbean ( Vigna radiata ), reveals that the mean gene diversity of Bambara groundnut was lower than azuki bean but higher than mungbean.

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
