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 findings
• Yield loss from crown rot ranged from not significant in five of the bread wheat varieties, the barley variety CommanderA and the durum variety JandaroiA up to 12.9% in the bread wheat variety EGA GregoryA.
• The recently released durum variety DBA LillaroiA produced a protein level of 15% which was over 1% higher than the two other durum entries JandaroiA and 190873.
• Crown rot infection did not significantly impact on the level of screenings in any of the entries due to limited expression under the wet seasonal conditions at this site in 2016. However, genetic differences were evident with screening levels which ranged from 3.2% in the durum line 190873 up to 17.6% in the bread wheat variety BeckomA.
Conclusions
Cereal crop and variety choice affected yield in the absence and presence of crown rot infection, which differed by 2.26 t/ha and 2.24 t/ha, respectively between the best and worst entries. The three durum entries were higher yielding relative to bread wheat and barley entries in both the added CR and no added CR treatments at this site in 2016. This was likely due to seasonal conditions (near full soil water profile at sowing plus 472 mm of in-crop rainfall), which limited crown rot expression.
Cereal crop and variety choice still provided a 9% to 35% yield benefit over growing the susceptible bread wheat variety EGA GregoryA under high levels of crown rot infection at Tamarang on the Liverpool Plains in 2016. This can maximise profit in the current 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.

PAWC 246 mm plant available soil water (0–120 cm) TRAIL RESULTS: Yield: In the no added CR treatment, yield ranged from 5.11 t/ha in the bread wheat variety SunmateA up to 7.38 t/ha in the durum variety DBA LillaroiA . The barley variety CommanderA, durum variety JandaroiA and five of the bread wheat entries (LPB12-0494, LRPB GauntletA, LRPB LancerA, SunguardA and LRPB SpitfireA) did not suffer significant yield loss under high levels of crown rot infection (added CR). In the remaining entries, yield loss ranged from 4.2% in the bread wheat variety LRPB ReliantA (0.26 t/ha) up to 12.9% in the bread wheat variety EGA GregoryA (0.77 t/ha). Only the bread wheat variety SunmateA was lower yielding than EGA GregoryA under high crown rot infection (added CR). The barley variety La TrobeA and two bread wheat varieties (SunguardA and LRPB SpitfireA) all produced yields equivalent to EGA GregoryA in the added CR treatment. All three durum entries produced yields higher than EGA Gregory. The bread wheat entries MitchA (0.87 t/ha), CoolahA (0.79 t/ha), LRPB ReliantA (0.70 t/ha), SuntopA (0.63 t/ha), LRPB FlankerA (0.61 t/ha), BeckomA (0.56 t/ha), LPB12-0494 (0.51 t/ha), LRPB GauntletA (0.36 t/ha) and LRPB LancerA (0.29 t/ha) were all higher yielding than EGA GregoryA under high levels of crown rot infection (added CR). The barley entries SpartacusA (0.54 t/ha), CommanderA (0.49 t/ha) and CompassA (0.49 t/ha) were also higher yielding than EGA GregoryA in the added CR treatment. Grain quality: Protein levels were relatively high at this site in 2016, which is likely a result of the high starting soil nitrogen levels. Protein levels in the bread wheat entries varied from 12.1% in MitchA, Coolah and LPB12-0494 up to 14.0% in LRPB SpitfireA (Table 1). Crown rot infection (added CR) did not significantly affect grain protein levels in any of the entries at this site in 2016. The recently released durum variety DBA LillaroiA achieved 1.1–1.2% higher grain protein levels (15.0%) than the other two durum entries in this experiment. Crown rot infection did not significantly affect the level of screenings in any of the entries at this site in 2016. However, genetic differences were evident with screening levels ranging from 3.2% in the durum line 190873 up to 17.6% in the bread wheat variety BeckomA |
