Other claims from this paper (13)
- Method / resource Enzyme immunoassay and GC-MS measurements of DON were highly correlated.
- Observation Mean grain DON content ranged from 20 to 129 mg/kg.
- Observation Mean Fusarium head blight severity ranged from 3.8 to 6.8 on a 1–9 scale.
- Observation Parental means generally resembled the means of their F3 progenies.
- Observation DON content and head blight rating both showed significant genotypic variance.
- Observation Genotype × environment interactions for DON and head blight were high.
- Observation Grain DON content had lower heritability than head blight rating, especially in rye.
- Association Phenotypic correlation between head blight severity and DON content was higher in wheat, at 0.8.
- Association Genotypic correlation between the traits was tight in both rye and wheat, at 0.8–0.9.
- Observation Three rye populations contained transgressive segregants with higher DON content.
- Observation One rye population contained transgressive segregants with higher Fusarium head blight resistance.
- Recommendation The authors recommend starting selection for low DON content and head blight resistance in F3.
- Recommendation The authors recommend selecting reduced head blight severity across environments to obtain low-DON lines indirectly.
