Other claims from this paper (9)
- Intervention effect Irradiation at meiosis had the strongest effects in the treatment year.
- Intervention effect Irradiation at tillering had comparatively small effects, attributed to counterselection.
- Association Mutation yield per irradiation unit decreased with increasing dose.
- Association In surviving material, mutation yield per radiation unit appeared to decrease with dose.
- Intervention effect Spike-emergence irradiation mostly produced fertility-affecting mutations, less so than meiosis irradiation.
- Intervention effect Mutation yield per unit radiation at spike emergence did not decline in the same way as at tillering and meiosis.
- Intervention effect Selection against induced changes was less pronounced after spike-emergence treatment.
- Intervention effect The proportion of mutations preserving fertility was greater after spike-emergence than meiosis irradiation.
- Recommendation The authors prefer spike-emergence irradiation methodologically and practically.
