Unraveling the genetic architecture of stripe rust resistance in ICARDA spring wheat

Stripe rust, also known as yellow rust, caused by Puccinia striiformis f. sp. tritici (Pst), is among the most destructive fungal diseases affecting global wheat productivity. Identifying genetic loci associated with Pst resistance is crucial for developing durable Pst-resistant wheat varieties. This study aimed to discover genetic markers linked to Pst-resistance in wheat using a 15 K single-nucleotide polymorphism (SNP) array. The QTLs detected represent promising candidates for marker-assisted selection, facilitating the development of wheat cultivars with enhanced resistance to Pst. Additionally, this study recommends incorporating the 36 consistently resistant lines into national and international wheat breeding programs to enhance Pst disease management efforts.
