Regional crown rot management – Gilgandra 2017

Abstract

Key findings •• The durum variety Jandaroi[PBR], plus the two bread wheat varieties LRPB Mustang[PBR] and LRPB Spitfire[PBR] were affected by frost at this site in 2017, which complicates interpretations. •• Yield loss from crown rot ranged from not significant in the four barley varieties and three of the 12 bread wheat varieties, up to 66% loss in the durum variety Jandaroi[PBR]. •• The four barley varieties were 0.99–1.42 t/ha higher yielding than the susceptible bread wheat variety EGA Gregory[PBR], where high levels of crown rot infection were present. •• The bread wheat varieties LRPB Reliant[PBR], Suntop[PBR], Mitch[PBR] and Sunguard[PBR] were also higher yielding (0.40–0.46 t/ha) than EGA Gregory[PBR] in crown-rot-infected plots.
