Abstract
The oilseed crop Brassica juncea carries many desirable traits; however, resistance to clubroot disease, caused by Plasmodiophora brassicae, is not available in this species. We are the first to report the clubroot resistant resynthesized B. juncea lines, developed through interspecific crosses between a clubroot resistant B. rapa ssp. rapifera and two susceptible B. nigra lines, and the stability of the resistance in self-pollinated generations. The interspecific nature of the resynthesized B. juncea plants was confirmed by using A- and B-genome specific SSR markers, and flow cytometric analysis of nuclear DNA content. Self-pollinated progeny (S1 and S2) of the resynthesized B. juncea plants were evaluated for resistance to P. brassicae pathotype 3. The S1 and S2 progenies of one of the resynthesized B. juncea lines were resistant to this pathotype. However, resistance was lost in 6 to 13% plants of the S2 progenies derived from the second resynthesized B. juncea line; this apparently resulted from the loss of the genomic region carrying resistance due to meiotic anomalies.

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
