Genetic dissection of the resistance to<i>Rice stripe virus</i>present in the<i>indica</i>rice cultivar ‘IR24’
Bibliographic record
Abstract
Rice stripe disease, caused by Rice stripe virus (RSV) and transmitted by the small brown planthopper (Laodelphax striatellus Fallen), is one of the most serious viral diseases of rice in temperate East Asian production regions. Prior quantitative trait loci (QTL) mapping has established that Oryza sativa L. subsp. indica 'IR24' carries positive alleles at the three loci qSTV3, qSTV7, and qSTV11-i. Here, we report an advanced backcross analysis based on three selected chromosome segment substitution lines (CSSLs), each predicted to carry one of these three QTL. Three sets of BC(4)F(2:3) populations were bred from a cross between the critical CSSL and its recurrent parent Oryza sativa L. subsp. japonica 'Asominori'. Both qSTV3 and qSTV11-i were detected in their respective population, but qSTV7 was not. An allelic analysis based on a known carrier of the major RSV resistance gene Stvb-i, which is located on chromosome 11, showed that qSTV11-i was not allelic with Stvb-i. A large mapping population was used to delimit the location of qSTV11-i to a 73.6-kb region. The de novo markers developed for this purpose will be useful as marker-assisted selection tools in efforts to introduce qSTV11-i into breeding programmes aiming to improve the level of RSV resistance.

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.
