Genetic diversity and relationships among<i>Prunus cerasifera</i>(cherry plum) clones
Bibliographic record
Abstract
Prunus cerasifera (Ehrh.) (cherry or Myrobalan plum) is a diverse species with several recognized subspecies and natural forms. It is used as rootstock or as an ornamental tree, and is considered to be one progenitor of the garden plum ( Prunus domestica L.). This study considers the genetic relationships among different P. cerasifera clones, including horticultural cultivars. Twenty nine P. cerasifera accessions of the Prunus Genetic Resources Collection of INRA were analysed using morphological traits, maternally inherited chloroplastic DNA (cpDNA) markers, and biparentally inherited microsatellite (SSR) markers. Ploidy information was obtained by flow cytometry. Multiple factorial correspondence analysis of morphological descriptors shows important differences between some clones, but most of the samples are grouped. Fifteen haplotypes of cpDNA were identified and clustered into three groups after statistical parsimony analysis. SSR markers revealed a total of 74 alleles, with a mean value of 10.6 alleles per locus. After analysis of ploidy level, P. cerasifera subsp. caspica was shown to have a hexaploid genome. Morphological and molecular data suggest that the taxonomic classification of some subspecies and of P. cerasifera subsp. caspica may need to be revised after analysis of additional individuals.

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.
