Regional crown rot management – Trangie 2016

Abstract

Key findings •• Yield loss from crown rot ranged from not significant in the bread wheat variety LRPB Reliant[PBR] up to 16.9% in the barley variety Compass[PBR]. •• Bread wheat variety choice affected yield in the presence of high levels of crown rot infection with three entries being between 0.45 t/ha and 0.85 t/ha higher yielding than the susceptible bread wheat variety EGA Gregory[PBR]. •• Grain protein levels were low across the site (mean of 9.8%) and varied from 8.7% in Mitch[PBR] up to 10.6% in LRPB Spitfire[PBR]. Crown rot infection did not affect protein levels in any entry. •• Crown rot infection caused a small (1–4%), but significant increase in screenings in the barley variety La Trobe[PBR] and all of the 13 bread wheat entries.
