Resistant Expression of High Level Resistant Mutant Rsb in Different Strains of R.solani,Much Application of N and Transplanting Density
Bibliographic record
Abstract
Rsb,mutant with high level resistance to sheath blight was found in BC2F2 of indica×japonica(Shuhui 955×Kitaake),which were much susceptible to sheath blight of rice.Resistant analysis of the pure Rsb,which was gotten by anther culture,was carried out in two manners.Firstly,it was done in general cultivation by using different international standard strains;Secondly,it was done in much quantity application of N and different transplanting density by using isolate with high pathogenicity,in which the application of N of high-yielding practices in Sichuan was designed as the lowest level.Results indicated that Rsb still had high level resistance to sheath blight under general cultivation and pathogenicity of AG 1-IA was the highest for all international standard strains tested.However,it did not show high level resistance to sheath blight and was middle type in Rush disease rating,only having endurance when it was transplanted in much quantity application of N and different transplanting density.The effect of transplanting density to infection of sheath blight was smaller than that of application of N.Analysis on correlation indicated that the disease rating of sheath blight had significant correlation with application of N at 1% level(r=0.867 3**,Fig.1).The resistance of Rsb is heritable and true,and it is controlled by major genes.The resistance response of same rice cultivar to sheath blight is mainly affected by the application quantity of N.

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.
