Varieties and advanced lines resistant to septoria diseases of wheat in Western Australia - Mexico, DF (Mexico) CIMMYT : 1999 - Printed

The development of bread wheats in Western Australia has resulted in the release of several varieties with improved response to the commonly occurring leaf spot diseases caused by Phaeosphaeria nodorum, Mycosphaerella graminicola, and Pyrenophora tritici-repentis. In a yield trial evaluating resistance to M. graminicola, susceptible varieties suffered 20-50% yield loss, while yield loss of resistant crossbreds and varieties was 0-15%. Similar responses were observed in most lines for grain weight when assessed in M. graminicola-infected row plots. In P. nodorum-infected row plots, susceptible varieties suffered 30-50% grain weight loss, while resistant lines suffered 0-30% loss in grain weight depending on year of testing.
