Abstract
An optimized transformation system was developed for maize elite inbred lines using Agrobacterium tumefaciens mediated gene transfer by studying various important factors which affect transformation efficiency.The system was performed by transient expression of GUS gene after embryogenic callus were placed on cocultivation medium for 3 days.The study with the embryogenic callus derived from immature embryos of maize inbred line Qi 319 and R 18-599 showed that the quality of the callus played an important role in the transformation process,the callus subcultured two times and pre-cultured for 7 days were the best for transformation.In addition,the study showed that the combination of EHA 105 and Qi 319 was better than EHA 105 and R 18-599 combination for transformation,which was concluded from the detection of transient GUS expression,since the average frequency of transient GUS expression of EHA 105-Qi 319(mean=31.20%) was significantly higher than that of EHA 105-R 18-599(mean= 23.74%) based on the test(t0.05).

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.
