Genetic variation and heritability of rutin and glutathione concentrations in asparagus spears
Bibliographic record
Abstract
Drinkwater, J. M., Tsao, R., Liu, R. and Wolyn, D. J. 2014. Genetic variation and heritability of rutin and glutathione concentrations in asparagus spears. Can. J. Plant Sci. 94: 1355–1362. Asparagus (Asparagus officinalis L.) spears contain numerous phytochemicals, including rutin (a flavonoid) and glutathione (a biothiol), that are beneficial to human health due to antioxidant or other activities. To assess the potential to increase phytochemical content through breeding, genetic variability was surveyed in diverse germplasm adapted to southern Ontario. Selected female and supermale genotypes were also hybridized in a partial diallel to estimate heritability and identify parents with good combining ability. Genetic variation for rutin (3.30 to 8.14 mg g −1 dry weight) was observed, while glutathione concentrations (5.37 to 7.86 µmol g −1 dry weight) did not differ significantly among tested genotypes. Combining ability effects were significant for rutin concentration and heritability was also moderate. From these results, breeding to improve the concentration of rutin, rather than that of glutathione, is most achievable in the germplasm tested.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
