Inheritance of resistance to powdery mildew (<i>Oidium lycopersicum</i>) and its linkage to an SSR marker in tomato hybrid DRW4409
Bibliographic record
Abstract
Powdery mildew is a serious disease for greenhouse and field tomatoes in North America. The main objective of this experiment was to study the genetic inheritance of resistance to powdery mildew in tomato hybrid DRW4409 and to identify simple sequence repeat (SSR) markers linked to the resistance gene. Analysis of a genetic population derived from DRW4409 showed that resistance to powdery mildew is controlled by a single dominant gene. Screening 158 SSR loci found that the SSR marker, LEat014, is linked to this gene at a map distance of 8.0 cM. To the best of our knowledge, this is the first report of an SSR linked to the resistance gene in DRW4409. Because of its co-dominant nature, this SSR should be useful to breeders in screening tomato plants for resistance to powdery mildew when DRW4409 is used as the resistance gene source.

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.
