RAPD analysis of genetic variability of regenerated seeds in the Canadian flax cultivar CDC Normandy
Bibliographic record
Abstract
Genetic variability of the original breeder seeds and twice regenerated seeds of the Canadian flax cultivar CDC Normandy was analyzed using RAPD markers. It was found that two (out of 98) RAPD loci derived from 16 informative UBC RAPD primers were polymorphic, confirming a narrow genetic variation for CDC Normandy. No off-types from the other flax accessions being simultaneously regenerated were found in the 48-seed sample of the 1998 regeneration, but one off-type in the 1999 regeneration was revealed at seven fixed recessive RAPD loci. The G-statistics calculated for the change in genotypic frequencies at two polymorphic RAPD loci over the two regeneration cycles were not statistically significant at the 0.05 level, suggesting no significant genetic change occurred in the regenerated accessions. These findings have practical implications for flax germplasm management, breeding program and commercial seed production.

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.
