Positions and estimated effects for quantitative trait loci on chromosome 5H with significant (p < 0.0001) effects on powdery mildew disease severity
| Population | QTL | Position (cM) | Markers | QTL effect estimate ± standard error | |
|---|---|---|---|---|---|
| 2011 | 2012 | ||||
| CLE210/Baudin | QPm.CLBa-5H | 139.5 | wri200-wri202 | − 2.6 ± 0.2 | − 2.7 ± 0.2 |
| Denar/Baudin | QPm.DeBa-5H | 150.7 | wri184-wri190 | − 2.9 ± 0.2 | − 2.2 ± 0.1 |
These statistics were derived using genetic linkage maps of chromosome 5H derived from KASP marker genotyping of the barley populations CLE210/Baudin and Denar/Baudin. Negative QTL effect estimates indicate that the allele from the more resistant parent (CLE210 or Denar) is associated with lower disease severity than the allele from the more susceptible parent (Baudin)
