Abstract
Backcross populations at advanced generations are useful in evaluating the agronomic traits from unadapted germplasms, such as wild species. In this study, we generated 159 backcross recombinant inbred lines (BRILs) at the BC2F8 generation between Oryza sativa Nipponbare (a recurrent parent) and O. rufipogon W630 (a donor parent). These BRILs were found to have nearly homozygous genome constitutions based on the marker genotypes at 180 SSR loci covering whole chromosomes. Since their selfed progenies have almost identical genotypes in each line, they were further used for QTL analysis of drought tolerance. Out of six QTLs detected, three were found to have wild alleles with favorable effects on drought tolerance. The present BRILs with known marker data can be applied to more QTL analyses of traits specific to wild species.

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 it
