Genetic Diversity of Cynodon dactylon accessions Based on RAMP Markers in Hengduan Mountains from Southwest of China
Bibliographic record
Abstract
Genetic diversity of 25 Cynodon dactylon accessions from Hengduan Mountains from southwest of China were analyzed by using RAMP(random amplified microsatellite polymorphism) markers.The results indicated that the polymorphism among the tested accessions was plentiful.A total of 56 bands were amplified based on 10 primer combinations,of which 39 bands were polymorphic,the percentage of polymorphic bands was 69.64.Two to six polymorphic bands could be amplified from each primer combination,with an average of 3.9 bands.The RAMP-based genetic similarity(GS) among 25 bermudagrass accessions ranged from 0.666 7 to 0.947 4,with a mean of 0.812 9.All the accessions could be distinguished by RAMP markers.The cluster analysis resluts showed that 25 accessions were classfied into 4 groups,which were correlated with the geographical distribution of the accessions to some degree.These results suggested that there actually existed plentiful genetic diversity of C.dactylon.RAMP marker was a useful method for analyzing the genetic diversity among C.dactylon accessions.

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.
