Study on a Stripe Resistance Gene and its Molecular Marker in Wheat ICA31 from Syria

Abstract

Abstract: Inheritance analysis showed that the wheat line ICA31 carries a single dominant gene conferring high resistance to stripe rust isolates CYR30，CYR31 and CYR32. Through allelic test, the resistance gene was different from Yr5, Yr10 and Yr15. By pedigree analysis, the resistance gene in ICA31 derived from the Syria common wheat line Xu18. Results of the SSR marker and BSA analysis showed that the resistance gene was located on 1BS and a diagnostic marker WMS11-193bp for the gene was identified. The genetic distance from the resistance gene to WMS11-193bp was 2.1 cM. The work is valuable for molecular-assisted selection in wheat breeding program against stripe rust.
