Resistance Sources to Xanthomonas fragariae in Non-octoploid Strawberry Species
Bibliographic record
Abstract
Forty-three accessions from 11 strawberry species were screened in the greenhouse for resistance to three strains of Xanthomonas fragariae Kennedy and King. Among the accessions tested, Pen-5 of Fragaria pentaphylla Losink expressed either no symptoms or a hypersensitive reaction, while accessions Pen-2 and Pen-4 developed either no symptoms or restricted water-soaked lesions. Two accessions of F. moschata Duch were characterized by reduced translucency at the inoculation site in the course of symptom development. These accessions, representing three resistance types, were classified as highly resistant, resistant, and moderately resistant, respectively, based on mean separation of disease severity ratings. The classifications proved to be consistent with the results from measurements of bacterial populations on inoculated leaves of those genotypes. The study suggests that species of F. pentaphylla and F. moschata harbour diversified sources of resistance. Resistant genotypes were not detected in F. nilgerrensis Schlect, F. daltoniana J. Gay, F. nubicola Lindl, F. gracilis Losinsk, F. iinumae Makino, F. vesca L., F. viridis Duch, or F. orientalis Losinsk.

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.
