GWAS for Stripe Rust Resistance in Wild Emmer Wheat (Triticum dicoccoides) Population: Obstacles and Solutions

Stripe rust is a devastating disease in wheat that causes substantial yield loss around the world. The most effective strategy for mitigating to develop resistant cultivars. wild relatives of are good sources resistance fungal pathogens. Here, we used genome-wide association study (GWAS) identify loci associated with stripe (causal agent: Puccinia striiformis f. sp. tritici) emmer (Triticum dicoccoides) at seedling stage, greenhouse, and adult plant field. We found two major contributing our panel were previously cloned seedling-stage gene, Yr15, adult-plant-stage Yr36. Nevertheless, detected 12 additional minor QTLs additionally contribute mapped locus on chromosome 3AS tentatively harbors novel gene. genotype phenotype data generated panel, together SNPs rust, provide valuable resource disease-resistance breeding durum bread wheat.
