Abstract
In major wheat-growing regions, rust diseases and common bunt significantly reduce wheat productivity, especially in years with favorable conditions for phytopathogen development and limited resistant cultivar use. Thus, the development of genetically resistant wheat cultivars carrying combinations of valuable resistance genes is an effective strategy to mitigate these losses. In this study, 156 advanced winter wheat breeding lines were evaluated for resistance to yellow (stripe) rust, leaf (brown) rust, and common bunt under an artificial infection background. Concurrently, molecular screening was performed using DNA markers to detect rust (Yr5, Yr10, Yr15, Lr9, Lr34/Yr18, and Lr37/Yr17) and common bunt resistance genes (Bt8, Bt9, Bt10, Bt11, and Bt12). Based on the integrated analysis of phenotypic and DNA marker-based molecular data, fourteen and five lines resistant to common bunt and yellow rust, respectively, were identified, and alleles associated with resistance were also detected. Notably, one line (9909) exhibited high resistance to both rust diseases and common bunt. These selected advanced breeding lines represent promising candidates for the development of wheat cultivars with enhanced disease resistance, thereby supporting sustainable productivity in wheat-growing regions.
