Abstract
Ion beam irradiation is a potential tool for inducing novel mutations in plants. We chose three crop species (rye, linseed, and faba bean) to determine the potential of nitrogen ion beam irradiation for inducing mutations. We tested ion beam irradiation with nitrogen ions at six different fluencies (5×105, 1×106, 5×106, 1×107, 5×107, and 1×108 N-ion cm-2) on dry grains. The three studied crop species had different sensitivities to the irradiation. Increased doses of ion irradiation had more effect on survival than on germination. Rye seedlings had the lowest survival rate at high doses of irradiation and significantly higher off-type plant phenotypes than the other two species. In M1 seedlings, stunted growth, failure to complete the plant life cycle and chlorophyll mutants were observed in all three species. Terminal-inflorescence mutations and sectional chimeras in faba bean were observed in the M2 generation. We conclude that ion beam irradiation is an effective tool for mutation breeding of diverse crop species when the appropriate dose is defined.

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
