Identification of novel sources of resistance to <i>Pea enation mosaic virus</i> in chickpea germplasm
Bibliographic record
Abstract
Chickpea can be seriously affected by Pea enation mosaic virus (PEMV) in the Pacific Northwest region of the USA and other areas of the world. Use of pesticides to manage PEMV vector transmission is ineffective and PEMV‐resistant chickpeas have not been identified. Therefore, the Cicer core collection consisting of 499 wild Plant Introduction (PI) accessions and improved cultivars representing 25 countries and two chickpea phenotypes (Desi and Kabuli) was evaluated for resistance to PEMV based on a 1 to 5 scale where 1 = symptomless and 5 = severe mosaic and stunting. Eight accessions were considered resistant to PEMV based on mean disease severity values equal to or less than 1·9 in repeated greenhouse tests. All of the resistant accessions to PEMV were of the Desi type and all originated from Iran or India. PI 450763 was the only Kabuli accession that demonstrated tolerance to PEMV. PEMV resistance was not detected in commercial chickpea cultivars or advanced breeding lines currently grown in the USA and Canada. This is the first report of chickpea germplasm with resistance to PEMV.

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.
