Other claims from this paper (9)
- Observation Stem rust has long been controlled through Rpg1 deployment.
- Method / resource A SCAR marker derived from Rpg1 made marker-assisted selection for stem rust resistance highly effective.
- Observation The durable adult plant spot blotch resistance QTL was identified in Steptoe/Morex.
- Observation That QTL was suppressed in Harrington/Morex and Dicktoo/Morex populations.
- Observation FHB resistance is controlled by many small-effect QTL.
- Observation Resistance sources for net blotch and SSLB were identified in barley accessions.
- Observation The net blotch and SSLB resistances are simply inherited.
- Observation The resistances are being introgressed into elite lines by phenotypic and marker-assisted selection.
- Recommendation Further multiple disease resistance breeding will require phenotypic screening, MAS and genomics discoveries.
