Abstract

Crown rot, caused by Fusarium pseudograminearum (Fpg), is an
important soilborne disease of winter cereals. Complete
resistance has yet to be reported in any wheat genotypes and
hence is an ongoing issue for Australian wheat growers. In order to understand the nature of the partial resistance identified to crown rot we have examined the patterns of disease and pathogen spread in both susceptible and partially resistant tissues. Field trials were designed to study disease symptom development and localisation of Fpg hyphae in the bread wheat varieties Puseas, Vasco and Sunco, and the line 2–49.
