QTL mapping of BNYVV resistance from the WB41 source in sugar beet
Bibliographic record
Abstract
The most important rhizomania-resistance gene in sugar beet is the Rz1 gene from the Holly Sugar Company in California, the source widely used to breed partially resistant varieties. Other important gene sources are WB41 and WB42, which both originate from Beta vulgaris subsp. maritima collected in Denmark, and which have been reported to be similar. The major resistance gene in WB42 is known as Rz2. We studied the resistance in WB41 and used markers to map the major resistance gene in this source, which we call Rz3. It was identified on chromosome III. This is the chromosome that Rz1 and Rz2 have been mapped to. Data from greenhouse tests and ELISA showed that Rz3 had incomplete penetrance, with heterozygotes varying widely in resistance levels. The involvement of additional minor genes in the strong resistance of the original WB41 source cannot be excluded.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
