Mapping Genes Conferring Resistance to Phytophthora Root Rot of Soybean, Rps1a and Rps7
Bibliographic record
Abstract
A linkage map was constructed for two Phytophthora sojae Kauf. +Gerd. root rot resistance genes, Rps1a and Rps7, in soybean (Glycine max (L.) Merr.) using microsatellite or simple sequence repeat (SSR) markers. An F2 population consisting of 81 individuals derived from a cross between OX281, which carries Rps7, and Mukden, which carries Rps1a, was used as the mapping population. A linkage map consisting of 10 SSR markers was first constructed using the computer software MapMaker/EXP 3.0. Rps1a and Rps7 were then placed at two different loci in the same linkage group with LOD scores of 2.88 and 9.16, respectively. Rps1a and Rps7 were linked at a distance of 13.8 cM. Rps1a was flanked by Satt159 (0.7 cM) and Satt009 (3.2 cM). Rps7 was flanked by Satt009 (10.6 cM) and Satt125 (29.1 cM).

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.
