Construction of F<sub>1</sub> Populations of <i>S. spontaneum</i> L. and Sugarcane and Molecular Detection of Genetic Diversity
Bibliographic record
Abstract
In order to obtain more hybrid offspring with excellent traits of Saccharum spontaneum L., this research used the YN 82-116 as a female parent to hybridize with the male parent GT 05-3595. The SSR primer MSSCIR1 combined with capillary electrophoresis technology was used to identify true and false hybrids of 48 hybrid progenies and to analyze genetic diversity. A total of 28 SSR fragments were amplified, the polymorphic bands ratio was 67.9%, and the F 1 generations were all real hybrids. The parental and offspring inheritance similarity coefficients range from 0.00 to 0.97, with an average of 0.58. The overall genetic similarity of filial generation is high, but the genetic differences are large. UPGMA cluster analysis showed that 37 offspring were clustered with their father, with a closer genetic distance and higher genetic similarity. The results can be used in the later stage to guide the process of cross breeding, improve breeding efficiency, and effectively introduce germplasm resources that are densely S. spontaneum L .

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.
