Reactions of field pea cultivars to four races of <i>Fusarium oxysporum</i> f. sp. <i>pisi</i>
Bibliographic record
Abstract
Reactions of the 117 field pea cultivars available in Canada were evaluated to the four common races (1, 2, 5, and 6) of Fusarium oxysporum Schl. f. sp. pisi (van Hall) Sny. and Hans, the causal agent of fusarium wilt, in growth chambers. Based on the visual assessment of foliar wilt symptoms, 49 cultivars were resistant to at least one of the four races, and the remaining 68 cultivars were susceptible to all four races. Of these resistant cultivars, Ascona and 44 other cultivars were resistant to race 1; Impala to race 2; Aladin to races 1 and 2; and Radley and Princess to races 2, 5, and 6. In an effort to standardize the methodology for screening field pea for resistance to the pathogen, other quantitative parameters including shoot length, vascular discoloration, and shoot and root dry weights were evaluated on selected cultivars. Correlation analysis revealed that foliar wilt symptoms and the reduction in shoot length were highly correlated (r = -0.90, P < 0.01). The result suggests that the reduction in shoot length could be used to supplement the visual severity rating for fusarium wilt in field pea. Key words: Field pea, Pisum sativum, fusarium wilt, Fusarium oxysporum f. sp. pisi, resistance

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.
