Genetic Diversity of <i>Phalaris arundinacea </i>Linn Germplasm Detected by SRAP Markers
Bibliographic record
Abstract
Sequence-related amplified polymorphism (SRAP) molecular marker was used to detect the genetic diversity of 25 accessions of Phalaris arundinacea Linn that collected from the USA, Russia, Kazakhstan, Canada, LanZhou and HuBei. The following results were obtained: 1) Sixteen primer pairs produced 131 polymorphic bands, with an average of 8.19 bands per primer pair. The percentage of polymorphic bands on average was 89.25%. The polymorphism information content (PIC) ranged from 0.784 to 0.9069, with an average of 0.8696. 2) The Neis genetic similarity coefficient of the tested accessions ranged from 0.5959 to 0.8425, and the average of Neis coefficient was 0.7422. These results suggested that there was rich genetic diversity among the resources of Phalaris arundinacea Linn. 3) Twenty-five accessions were clustered into five groups. Moreover, the accessions from the same or similar origin frequently clustered into one group. The findings implied that the correlation among the resources, geographical and ecological environment.

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.
