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.

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.

Key messages

Key findings

• Yield loss from crown rot ranged from 7.6% in the bread wheat variety LRPB SpitfireA up to 29.1% in the barley variety CommanderA. • Bread wheat variety choice affected yield in the presence of high levels of crown rot infection with nine entries being 0.30 t/ha to 1.33 t/ha higher yielding than the susceptible bread wheat variety EGA GregoryA.

• Grain protein levels varied from 12.0% in MitchA up to 15.8% in the recently released durum variety DBA LillaroiA. Crown rot infection did not affect any grain protein level in any entry.

• Screening levels varied from 2.2% in the barley variety CompassA up to 9.5% in the bread wheat line LPB12-0494.

• Crown rot infection did not affect screening levels in any entry.

Conclusions

Cereal crop and variety choice provided a 7–33% yield benefit over growing the susceptible
bread wheat variety EGA GregoryA under high levels of crown rot infection at Bullarah in
2016. This could have maximised profit in the 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.

TRIAL RESULTS:

Yield

In the no added CR treatments, yield ranged from 3.76 t/ha in the barley variety SpartacusA up
to 5.86 t/ha in the bread wheat variety BeckomA .
All entries suffered significant yield loss under high levels of crown rot infection (added CR),
which ranged from 7.6% in the bread wheat variety LRPB SpitfireA (0.44 t/ha) up to 29.1% in
the barley variety CommanderA (1.32 t/ha).
All four barley varieties were lower yielding than EGA GregoryA under high crown rot
infection (added CR). The bread wheat entries (LPB12-0494, SunguardA and LRPB GauntletA)
all produced a yield equivalent to EGA GregoryA in the added CR treatment.
The bread wheat entries LRPB SpitfireA (1.33 t/ha), BeckomA (0.98 t/ha), MitchA (0.81 t/ha),
CoolahA (0.71 t/ha), SunmateA (0.61 t/ha), LRPB FlankerA (0.48 t/ha), LRPB LancerA
(0.39 t/ha), LRPB ReliantA (0.33 t/ha) and LPB12-0494 (0.30 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 from 12.0% (MitchA) up to
15.8% (DBA LillaroiA). The recently released durum variety DBA LillaroiA achieved
0.9–1.2% higher grain protein levels than the other two durum entries in the experiment.
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 2.2% in the barley variety CompassA up to 9.5% in the bread
wheat line LPB12-0494. Crown rot infection (added CR) did not significantly
affect grain protein levels in any of the entries at this site in 2016. The three durum varieties
produced similar screenings levels to each other, in the range of 4.2–4.8%.
