Wheat Germplasm Samples Susceptible to Puccinia striiformis f. sp. tritici Collected from Natural Fields in Uzbekistan, 2023-2025
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), threatens wheat production in Central Asia. This study investigates host genetic composition and environmental factors driving pathogen lineage turnover in Uzbekistan. From 2023-2025, 793 paired host-pathogen samples were collected across agroecological zones and genotyped using Target sequencing (GenoBaits panels 100k ).These wheat host genomic data, combined with previously deposited Pst pathogen data (BioProject: PRJNA1514982), will enable genome-wide association studies to identify host resistance loci against specific Pst lineages, supporting wheat breeding for durable stripe rust resistance in Central Asia.
