Regional crown rot management – Tamarang 2016

Abstract

Key findings •• Yield loss from crown rot ranged from not significant in five of the bread wheat varieties, the barley variety Commander[PBR] and the durum variety Jandaroi[PBR] up to 12.9% in the bread wheat variety EGA Gregory[PBR]. •• The recently released durum variety DBA Lillaroi[PBR] produced a protein level of 15% which was over 1% higher than the two other durum entries Jandaroi[PBR] 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 Beckom[PBR].
