Wheat production faces significant challenges from fungal plant pathogens capable of adapting to commonly used resistance genes. Consequently, there is an increasing need for new, durable, disease-resistant genes to prevent pathogen-induced yield losses without relying on chemical plant protection products.

Although the barley gene pool has been identified as a potential source of resistance genes effective against wheat pathogens, barley genetic resources have not yet been extensively utilized for wheat improvement. This study aims to reveal the genetic landscape of barley resistance against non-adapted wheat pathogens, specifically powdery mildew and stripe rust, within a genetically diverse barley panel.

By employing a novel micro- and macro-phenotyping approach and leveraging a high-throughput phenotyping platform alongside available genotypic data, we aim to uncover the genetic basis of non-host resistance that could be harnessed to develop durable disease resistance in wheat.
