Regional crown rot management – Garah 2016

Abstract

Key findings •• Yield loss from crown rot ranged from not significant in the barley varieties Spartacus[PBR] and Commander[PBR] up to around 20% in the barley variety Compass[PBR] and bread wheat varieties EGA Gregory[PBR] and LRPB Flanker[PBR]. •• Bread wheat variety choice affected yield in the presence of high levels of crown rot infection with five entries being between 0.32 t/ha to 0.57 t/ha higher yielding than the susceptible bread wheat variety EGA Gregory[PBR]. •• Grain protein levels varied from 11.3% in Mitch[PBR] up to 14.9% in LRPB Spitfire[PBR]. Crown rot infection did not affect protein levels in any entry. •• Crown rot infection increased the level of screenings in all four barley varieties and the two bread wheat varieties Sunmate[PBR] and LRPB Reliant[PBR].
