Trial details

Aims

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.

Key messages

Key findings

• Yield loss from crown rot ranged from not significant in the barley varieties SpartacusA and CommanderA up to around 20% in the barley variety CompassA and bread wheat varieties EGA GregoryA and LRPB FlankerA.

• 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 GregoryA.

• Grain protein levels varied from 11.3% in MitchA up to 14.9% in LRPB SpitfireA. 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 SunmateA and LRPB ReliantA.

Conclusions

Cereal crop and variety choice provided a 7–13% yield benefit over growing the susceptible
bread wheat variety EGA GregoryA under high levels of crown rot infection at Garah 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.

Treatments Varieties (20)

• Four barley varieties: CommanderA, CompassA, La TrobeA and SpartacusA.

• Three durum varieties: JandaroiA and 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.

TRIAL RESULTS:

Yield In the no added CR treatment, yield ranged from 3.54 t/ha in the barley variety CommanderA up to 5.61 t/ha in the bread wheat variety LRPB FlankerA .

Only two of the barley varieties, SpartacusA and CommanderA, did not suffer significant yield loss under high levels of crown rot infection (added CR). In the remaining entries, yield loss ranged from 7.6% in the bread wheat variety MitchA (0.40 t/ha) up to 21.6% in the barley variety CompassA (0.93 t/ha).

All four barley varieties, the durum variety DBA LillaroiA and the bread wheat variety LRPB SpitfireA were lower yielding than EGA GregoryA under high crown rot infection (added CR). The remaining durum entries and six of the bread wheat varieties (LRPB GauntletA, SunguardA, LRPB ReliantA, LRPB LancerA, LRPB FlankerA and BeckomA) all produced yields equivalent to EGA GregoryA in the added CR treatment .

The bread wheat entries SunmateA (0.57 t/ha), MitchA (0.49 t/ha), LPB12-0494 (0.36 t/ha), SuntopA (0.34 t/ha) and CoolahA (0.32 t/ha) were all higher yielding than EGA GregoryA under high levels of crown rot infection (added CR).

Grain quality:

Protein levels were relatively high at this site in 2016 and ranged between 11.3% (MitchA) up to 14.9% (LRPB SpitfireA). 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 1.9% in the bread wheat variety LRPB LancerA up to 7.9% in the barley variety La TrobeA .

Screening levels were increased in the added CR treatment, with all four barley varieties and two of the bread wheat varieties SunmateA and LRPB ReliantA by between 1.7 to 5.6%. 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 2.9% in the bread wheat variety LRPB LancerA up to 10.7% in the barley variety La TrobeA
