Genetic diversity in a collection of borage (<i>Borago officinalis</i>) germplasm
Bibliographic record
Abstract
The common borage, Borago officinalis L., is of Euro-Mediterranean origin, but is found extensively in the wild. It is also cultivated as a garden plant, crop vegetable, or pharmaceutical herb. Analysis of random amplified polymorphic DNAs (RAPDs) revealed high levels of genetic diversity among 10 borage wild accessions and seven cultivars, which included five white-flowered selections grown in northern Spain for petiole production, and two blue-flowered lines used medicinally. These latter two cultivars and populations, sampled far from the original habitat of the species, were closely related to wild borage populations from northern Europe. The two medicinal cultivars did not differ from each other, while those used for petiole production differed significantly from their Spanish wild relatives. Differences among the 17 populations accounted for 41.4% of the total genetic variability; this value increased to 50.8% when only the 10 wild populations were considered. Population differentiation and within-population variability are discussed in relation to mating system, selection, and conservation practices.

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.
