Genetics and resistance Resistance to Entomosporium mespili among cultivars of saskatoon, Amelanchier alnifolia
Bibliographic record
Abstract
Abstract: Saskatoon (Amelanchier alnifolia Nutt.) cultivars were evaluated for their resistance to Entomosporium leaf and berry spot disease, caused by the fungal pathogen Entomosporium mespili DC. (Sacc.). Leaves and fruit from naturally infected plants of saskatoon cultivars were evaluated for disease incidence and severity. Detached leaves of these cultivars were also evaluated for disease severity after inoculation with a conidiospore suspension under controlled conditions. Leaf age was an important factor in disease response of detached leaves, with older leaves generally displaying reduced susceptibility. Comparisons of disease response for inoculated and naturally infected leaves of various cultivars revealed similar rankings and significant correlation coefficients. Analysis of data from all experiments revealed significant differences (P £ 0.05) in disease response among saskatoon cultivars. Leaf disease response of saskatoon cultivars to E. mespili was classed into four groups: (1) those that restricted infection and sporulation, e.g., Success; (2) those that restricted sporulation, e.g., Regent; (3) those that reduced sporulation, e.g., Northline; and (4) those that reduced neither infection or sporulation, e.g., Pearson II. Most cultivars had moderate to high values for the incidence and severity of leaf and fruit infection. Resistant cultivars were distinguished by their ability to restrict fungal sporulation on leaves and fruit. Among the saskatoon cultivars evaluated in this study, Parkhill, Regent, and Success showed consistently lower values for the incidence and severity of fungal sporulation on leaves and fruit.

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.
