Reactions of field pea varieties to three isolates of Uromyces fabae
Bibliographic record
Abstract
Reactions of 93 field pea varieties to three isolates of Uromyces fabae (Pers.) de Bary (Uf-1, Uf-2, and Uf-3) were measured as leaf area with symptoms (LAS) under controlled environmental conditions. Significant differences ( P < 0.05) were observed from pea varieties and rust isolates, and variety ×isolate interaction. Of these varieties, Tara and Century were mo st resistant (LAS <2%) to both Uf-1 and Uf-3 isolates; Victoria and Topper were most resistant to Uf-2 only; and Titan, Tipu, Emerald, and Yellowhead were most resistant to Uf-3 only. The remaining varieties had LAS of 2-67% for Uf-1, 2-86% for Uf-2, and 2 -45% for Uf-3, and were considered susceptible to the respective isolates. Over the average of 93 varieties, Uf-3 had LAS of 8.6% and was considered a less virulent isolate compared to Uf-1 (16.2%) and Uf-2 (15.2%). It is suggested that several different pathogenic isolates are required to test pea lines for rust resistance. A growth room inoculation and assessment method was developed in this study and can be used for evaluating pea lines for susceptibility to U. fabae.

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.
