ABSTRACT = {Barley (<i>Hordeum vulgare</i> L.) is a significant global crop that thrives in various climatic and drought-stress conditions. Furthermore, increased drought intervals and more significant weather variability resulting from climate change can affect the severity of plant diseases. Therefore, two primary objectives of integrated disease management regarding climate change are identifying cultivars resistant to foliar diseases and understanding disease progression under abiotic stress. In the current study, we assessed the quantitative foliar disease resistance of 17 commercial barley cultivars under both normal and water stress conditions over two growing seasons (from 2020/21 to 2021/22). The findings demonstrated a reduced incidence of foliar fungal diseases (leaf rust, net blotch, and powdery mildew) under severe drought stress relative to standard irrigated field conditions. The barley cultivars (Giza 130, Giza 131, and Giza 133) demonstrated significant differences across all disease resistance indices. In addition, the study aimed to molecularly characterize 17 commercial barley varieties using single-cell DNA testing (SCoT) to identify genetic polymorphism and specific markers for each genotype. Eight SCoT primers were employed to investigate the genetic polymorphism among 17 barley varieties. Furthermore, these cultivars exhibited optimal performance for the majority of agricultural attributes examined, both under normal and water-stressed conditions.},
