Abstract
DNA fingerprinting is a useful tool for the registration and identification of new cultivars,the protection of cultivars' rights and evaluation of genetic diversity.In this study,10 pairs of core SSR makers were screened among 500 pairs of SSR primers to establish DNA fingerprinting of japonica rice cultivars attended regional trials In the Northeast the past two years.The result of genetic diversity showed that only 300 alleles were detected in 100 polymorphic loci with the average number of 3,the average number of PIC was 0.3753 and Shannon-Weiner index was 0.6445,significantly lower than others rice regions.So,the current genetic diversity of germplasm resources on rice in Northeast Region of China was correspondingly narrow.

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
