Crown rot (CR) caused predominantly by the fungus Fusarium pseudograminearum (Fp), remains a major constraint to the production of winter cereals in the northern grains region. Cereal varieties differ in their resistance to crown rot which can have a significant impact 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 impact of crown rot on the yield and quality of four barley, three durum and 13 bread wheat varieties
Conclusions
Cereal crop and variety choice provided a 6–20% yield benefit over growing the susceptible bread wheat variety EGA GregoryA under high levels of crown rot infection at Parkes 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.

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; (liste Results: Yield In the no added CR treatment, yields ranged from 4.82 t/ha in the durum line 190873 up to 5.51 t/ha in the bread wheat variety CoolahA . The bread wheat varieties MitchA and BeckomA did not suffer significant yield loss under high levels of crown rot infection (added CR). In the remaining entries, yield loss ranged from 5.7% in the bread wheat variety CoolahA (0.31 t/ha) up to 18.6% in the bread wheat variety LRPB FlankerA (1.02 t/ha). No entry was lower yielding than EGA GregoryA under high crown rot infection (added CR). The barley varieties CommanderA and CompassA, the three durum entries and bread wheat varieties LRPB GauntletA, LRPB SpitfireA and LRPB FlankerA all produced yields equivalent to EGA GregoryA in the added CR treatment (Table 1). The barley varieties SpartacusA (0.69 t/ha) and La TrobeA (0.59 t/ha), along with the bread wheat entries CoolahA (0.86 t/ha), MitchA (0.84 t/ha), SuntopA (0.75 t/ha), LRPB LancerA (0.72 t/ha), BeckomA (0.71 t/ha), SunmateA (0.50 t/ha), LRPB ReliantA (0.36 t/ha), SunguardA (0.35 t/ha) and LPB12-0494 (0.28 t/ha) were higher yielding than EGA GregoryA under high levels of crown rot infection Grain quality Only moderate protein levels were achieved at this site in 2016, which ranged from 9.2% (CoolahA) up to 11.5% (SpartacusA). Crown rot infection (added CR) did not significantly affect grain protein levels in any of the entries at this site in 2016. In the no added CR treatment, screening levels ranged from 1.0% in the barley variety CompassA up to 4.0% in the bread wheat line LPB12-0494 . Screening levels increased by 0.6–1.4% in the added CR treatment with the four barley varieties and the bread wheat entries SunmateA, LRPB ReliantA, SunguardA and LPB12-0494. In the remaining entries, there was no significant difference in the level of screenings between the no added CR and added CR treatments. In the added CR treatment, screening levels ranged from 1.5% in the durum line 190873 up to 4.8% in the bread wheat line LPB12-0494 . |
