  abstract = {Two barley populations, i.e. 135 doubled haploid {(DH)} lines of the cross {'Igri'} (rrs1) x {'Triton'} {(Rrs1)} {(I} x T) and 76 {DH} lines of the cross {'Post'} x {'Vixen'} (both rrs1) {(P} x V), were analysed to identify {QTL} for Rhynchosporium secalis resistance independent of the Rrs1 locus by using the single spore R. secalis isolate 271 {(Rrs1-virulent).} A major {QTL} with its positive allele derived from cv. {'Triton'} was detected in the I x T population on chromosome {2HS} explaining almost 80\% of the phenotypic variance. Thus, it can be considered as an R-gene corresponding to the already described {Rrs15(CI8288)} on chromosome {2HS.} In addition, two minor {QTL} were identified, one in the centromeric region of {6H} in a highly polymorphic region with already several mapped R-genes and a second one at the end of the short arm of chromosome {7H} which may be an allele of Rrs2 because of its chromosomal position. Regarding the {DH} population P x V different minor {QTL} were identified on chromosomes {6H} and {7H.} The first one is corresponding to the genomic region of the Rrs13 gene whereas the {QTL} on chromosome {7H} maps in a genomic region where several R-genes against different pathogens have been localized. A comparison of both {QTL} analyses reveals no R. secalis isolate 271-specific resistance locus but leads to the hypothesis that two of the identified {QTL} may be alleles of the R-genes {Rrs15(CI8288)} and Rrs2.},
