Yield response of 32 bread wheat entries across three sowing dates – Trangie 2016

Abstract

Key findings •• The quicker maturing varieties LRPB DartA, Hatchet[PBR] Livingston[PBR], Mace[PBR], Sceptre[PBR], Mitch[PBR] and Suntop[PBR] were generally lower yielding than other entries at SD1, but were more yield competitive with other entries at SD2 and SD3. •• The longer season varieties EGA Wedgetail[PBR] (6.08 t/ha) and EGA Eaglehawk[PBR] (5.88 t/ha) were the highest yielding varieties at SD1, followed by Cutlass[PBR] (5.51 t/ha) and LRPB Flanker[PBR] (5.36 t/ha). •• The mean yield at SD1 (4.89 t/ha) was not significantly different from SD2 (4.63 t/ha), but SD3 (3.56 t/ha) was significantly lower yielding than either SD1 or SD2. •• All varieties yielded their lowest from SD3. •• Protein percentages were low to moderate (mean of 9.8% for SD2 and 10.3% for SD1) with no significant difference from SD for any of the entries.
