Virulence Profiles and Genome-Wide Association Study for Isolates Collected from Australian Lentil-Growing Regions.

, the causal organism of Ascochyta blight (AB) of lentil (), has been shown to produce an avirulence effector protein that mediates AB resistance in certain lentil cultivars. The two known forms of the effector protein were identified from a biparental mapping population between isolates that have reciprocal virulence on 'PBA Hurricane XT' and 'Nipper'. The effector AlAvr1-1 was described for the PBA Hurricane XT-avirulent isolate P94-24 and AlAvr1-2 characterized in the PBA Hurricane XT-virulent isolate Kewell.

Phenotypic and Genotypic Diversity of Populations in Southern Australia.

Speg. is a serious foliar fungal disease of faba bean and a constraint to production worldwide. This study investigated the phenotypic and genotypic diversity of the pathogen population in southern Australia and the pathogenic variability of the population was examined on a differential set of faba bean cultivars.

Changes in Aggressiveness of the Ascochyta lentis Population in Southern Australia.

Anecdotal evidence identified a change in the reaction of the resistant lentil cv Nipper to ascochyta blight in South Australia in 2010 and subsequent seasons, leading to infection. This study investigated field reactions of lentil cultivars against Ascochyta lentis and the pathogenic variability of the A. lentis population in southern Australia on commonly grown cultivars and on parental germplasm used in the Australian lentil breeding program.
