Validation of a SNP-KASP marker for the Fusarium head blight resistance QTL on chromosome 5AS

: Fusarium head blight is a devastating wheat disease with a significant economic impact. Fhb5 is an important quantitative trait loci conferring Type I resistance to Fusarium head blight. In this study, we accessed the usability of a Kompetitive allele specific PCR marker for the QTL on Fhb-5AS . The KASP clustering results were compared with the linked SSR marker, wmc705 for Qfhb-5AS . Our results indicate that the single nucleotide polymorphic locus wsnp_Ra_c24707_34262900 ( IWA7777 ) provides reliable information for Qfhb-5AS based resistance and would be amenable to masker-assisted selection, introgression of the resistance loci and pyramiding of Fusarium head blight resistance in wheat cultivars.
