Other claims from this paper (10)
- Intervention effect Low EMS concentrations stimulated germination.
- Intervention effect Higher EMS concentrations progressively reduced germination.
- Intervention effect Gamma radiation induced persistent dwarfism, altered leaf morphology and chlorophyll defects in M1 plants.
- Intervention effect EMS treated M1 plants resembled wild type controls.
- Intervention effect Gamma radiation at 50 Gy induced early flowering.
- Intervention effect Gamma radiation at 50 Gy increased sterility.
- Intervention effect EMS delayed flowering.
- Intervention effect EMS reduced sterility.
- Observation Altered leaf phenotypes and chlorophyll defects occurred in M2 progeny.
- Recommendation The authors recommend applying a range of mutagen doses to mitigate infertility.
