Crown rot (CR) caused predominantly by the fungus Fusarium pseudograminearum (Fp), remains a major constraint to winter cereal production in the northern grains region. Cereal varieties differ in their resistance to crown rot, which can have a significant affect on their relative yield in the presence of this disease.
This experiment was one of 11 conducted by NSW DPI in 2016 across central/northern NSW extending into southern Qld; to examine the effects from crown rot on the yield and quality of four barley, three durum and 13 bread wheat varieties.

Treatments Varieties (20) • Four barley varieties: CommanderA, CompassA, La TrobeA and SpartacusA. • Three durum varieties: JandaroiA and DBA LillaroiA plus the numbered line 190873. • Thirteen bread wheat varieties: EGA GregoryA, LRPB FlankerA, BeckomA, CoolahA, SunmateA, LRPB LancerA, LRPB ReliantA, LRPB GauntletA, LRPB SpitfireA, MitchA, SuntopA and SunguardA; (listed in order of increasing resistance to crown rot) plus one numbered line LPB12-0494. Pathogen treatment: Added or no added crown rot at sowing using sterilised durum grain colonised by at least five different isolates of Fp at a rate of 2.0 g/m of row at sowing. 128 | NSW Department of Primary Industries Results Yield In the no added CR treatment, yield ranged from 3.85 t/ha in the barley variety CommanderA up to 5.92 t/ha in the bread wheat variety BeckomA . The bread wheat varieties BeckomA, SuntopA, LRPB GauntletA and LRPB ReliantA did not suffer significant yield loss under high levels of crown rot infection (added CR). The remaining entries suffered significant yield loss under high levels of crown rot infection (added CR), ranging from 4.2% in the bread wheat variety SunmateA (0.25 t/ha) up to 14.9% in the barley variety CompassA (0.68 t/ha). All four barley varieties and all three durum entries were lower yielding than EGA GregoryA under high crown rot infection (added CR). The bread wheat varieties LRPB SpitfireA, SunguardA, LRPB FlankerA and LRPB ReliantA all produced yields equivalent to EGA GregoryA in the added CR treatment . The bread wheat entries BeckomA (0.76 t/ha), SunmateA (0.60 t/ha), SuntopA (0.56 t/ha), MitchA (0.52 t/ha), CoolahA (0.52A t/ha), LRPB LancerA (0.41 t/ha), LRPB GauntletA (0.34 t/ha) and LPB12-0494 (0.29 t/ha) were all higher yielding than EGA GregoryA under high levels of crown rot infection Grain quality: Protein levels were relatively high at this site in 2016, ranging from 11.9% (BeckomA) up to 14.7%. Crown rot infection (added CR) did not significantly affect grain protein levels in any of the entries at this site in 2016 Screening levels ranged from 4.4% in the barley variety CompassA and bread wheat variety CoolahA up to 9.3% in the barley variety SpartacusA . Crown rot infection (added CR) did not significantly affect grain protein levels in any of the entries at this site in 2016. Conclusions: Bread wheat variety choice provided a 6–15% yield benefit over growing the susceptible bread wheat variety EGA GregoryA under high levels of crown rot infection at Edgeroi in 2016. This could have maximised profit in this growing season, but will not reduce inoculum levels for subsequent crops because all winter cereal varieties are susceptible to crown rot infection. Winter cereal crop and variety choice is therefore not the sole solution to crown rot, but rather just one element of an integrated management strategy to limit losses from this disease. |
