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 effect 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.

Treatments: Varieties (20)
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. Results: Yield In the no added CR treatment, yield ranged from 2.16 t/ha in the barley variety La TrobeA up to 3.55 t/ha in the bread wheat variety BeckomA. Waterlogging at early growth stages (up to GS32) was evident at this site in 2016, which appeared more pronounced in the barley varieties than in the bread or durum wheat entries. The durum variety DBA LillaroiA and seven of the bread wheat varieties (MitchA, LRPB FlankerA, LRPB SpitfireA, SuntopA, LRPB ReliantA, LRPB GauntletA and SunguardA) did not suffer significant yield loss under high levels of crown rot infection (added CR). In the remaining entries, yield loss ranged from 9.6% in the bread wheat variety CoolahA (0.32 t/ha) up to 32.9% in the durum variety JandaroiA (0.84 t/ha). All four barley varieties and all three durum entries were lower yielding than EGA GregoryA under high crown rot infection (added CR). With the exception of MitchA, all the bread wheat entries produced a yield equivalent to EGA GregoryA in the added CR treatment . The bread wheat variety MitchA (0.41 t/ha) was the only entry that was higher yielding than EGA GregoryA under high levels of crown rot infection Grain quality Protein levels were low at this site in 2016 and ranged between 7.7% (MitchA) up to 10.1% (190873; Table 1). The low protein levels were likely related to denitrification that occurred with transient water logging at the site early in the season. Crown rot infection (added CR) did not significantly affect grain protein levels in any of the entries at this site in 2016. 120 | NSW Department of Primary Industries In the no added CR treatment, screening levels ranged from 1.7% in the barley variety CompassA up to 8.0% in the bread wheat variety SunmateA (Table 1). Screening levels were increased by around 1–2% in the added CR treatment with the barley variety La TrobeA and the bread wheat entries MitchA, BeckomA, CoolahA, LRPB FlankerA, SunmateA, EGA GregoryA, LRPB ReliantA, LRPB GauntletA, LPB12-0494 and LRPB LancerA. 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 2.1% in the barley variety CompassA up to 10.3% in the bread wheat variety SunmateA. |
