Identification of candidate chromosome region of Sbwm1 for Soil-borne wheat mosaic virus resistance in wheat.

ABSTRACT: Soil-borne wheat mosaic virus (SBWMV) causes a serious viral disease that can significantly reduce grain yield in winter wheat worldwide. Using resistant cultivars is the only feasible strategy to reduce the losses caused by SBWMV. To fine map the resistance gene Sbwm1, 205 wheat accessions was genotyped using wheat Infinium iSelect Beadchips with 90 K SNPs. Association analysis identified 35 SNPs in 12 wheat genes and one intergenic SNP in the Sbwm1 region that showed a significant association with SBWMV resistance. Those SNPs were converted into Kompetitive Allele-Specific Polymerase assays (KASP) and analyzed in two F₆-derived recombinant inbred line (RIL) populations derived from the crosses between two resistant cultivars 'Wesley' and 'Deliver' and a susceptible line 'OK038
