Other claims from this paper (5)
- Intervention effect The physical mutagenic agent was nearly always superior to the chemical agent in oat, giving a larger number of phenotypic classes of shorter plants regardless of cross or generation.
- Observation The mutant oat genotypes showed differentiated sensitivity to doses of the applied agents.
- Intervention effect The authors conclude the mutagenic agents are efficient in altering genetic variability of plant height both upwards (taller) and downwards (shorter).
- Intervention effect The largest degree of genetic divergence for the new dwarfing genes in the M2 generation of UFRGS 10 was obtained with the physical agent at 100 Gy.
- Intervention effect The largest degree of dominance for the new dwarfing genes in the M2 generation of UFRGS 10 was obtained with the chemical agent at 0.5%.
