Durability of resistance to rust in sunflower: implications for resistance breeding.
Bibliographic record
Abstract
Sunflower rust is caused by Puccinia helianthi Shw. and is an important disease in Argentina, Australia, Canada, Egypt, Israel, Turkey, USA and the former USSR. Sunflower rust is a macrocyclic, heterothallic and autoecious fungus, surviving mainly in plant debris in soil in the form of teliospores. New races of P. helianthiare continuously evolving and overcoming resistance genes, resulting in a continuous threat for the crop. The deployment of hybrids with simple resistances has exacerbated this problem. Combination of the appropriate R-genes could result in a resistance more difficult to overcome. The identification and characterization of new durable sources of sunfl ower rust resistance is a high priority for both researchers and industry. There is a possibility of breeding for high coumarin content to improve resistance at early stages of fungal development.

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.
