摘要: Identification and genetic analysis of yellow rust resistance have suggested that wheat line R55 carries single dominant gene conferring yellow rust resistance. The bulked segregant analysis (BSA) for an F-2 population using microsatellite marker technique has indicated that the yellow rust resistance gene is located on the short arm of chromosome 1B, tightly linked to the microsatellite markers WMS11-193 bp and WMS18-184 bp, the linkage distance between the markers and the gene is 1.9 cM. This gene has been formally named Yr26. It is inferred from the pedigree, resistance and gene locus analysis that the Yr26 has been transferred from Triticum turgidum L. and is different from the other known yellow rust resistance genes.
