Abstract Key message The GWAS and testing with Yr gene linked markers identified 109 loci including 40 novel for all-stage adult plant stage resistance to stripe rust in 459 US contemporary hard winter wheat genotypes. Stripe is a destructive disease, caused by Puccinia striiformis f. sp. tritici ( Pst ). To identify sources of wheat, panel Great Plains genotypes was evaluated at the seedling against five races field environments Oklahoma, Kansas, Washington. results showed that 7–14% were resistant stage, whereas 32–78% across environments, indicating presence resistance. Sixteen displayed broad spectrum all environments. further genotyped using 9858 single-nucleotide polymorphisms (SNPs) generated from multiplex restriction amplicon sequencing (MRASeq) functional DNA known ) genes Yr5 , Yr15 Yr17 Yr18 Yr29 Yr36 Yr40 Yr46 QYr.tamu-2B . A genome-wide association study (GWAS) performed genotypic phenotypic data, which 110 SNPs be significantly associated response. In addition, detected their panel. This genomic regions not previously characterized genes. These findings offer significant opportunities diversify enhance wheat.
