Analysis of Genetic Diversity and Relationship of <i>Jacaranda mimosifolias</i> Based on ISSR Molecular Markers Technique
Bibliographic record
Abstract
The genetic diversity and relationship of Jacaranda mimosifolias from 19 provenances including 21 germplasms in China were studied by ISSR molecular markers technique. 53 bands were amplified by using 10 selected primers from all the 33 primers, of which 44 bands were polymorphic, with the polymorphism ratio of 83.02%. Each primer could amplify 5.3 bands in average. The average number of tested alleles (Na) , effective alleles (Ne) , Nei’s gene diversity index (H) and Shannon’s information index (I) were 1.83, 1.45, 0.27, 0.40, respectively. ISSR molecular marker cluster analysis research shows 21 J. mimosifolias germplasm resources could be divided into two groups, and the genetic diversity is high. Their genetic relationship is not strongly related to geographical origin of cultivation area. In this study, the relatively accurately molecular identification of the germplasm resources of J. mimosifolias was carried out, which will provide a theoretical basis for the breeding of the improved varieties.

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.
