Abstract excerpt

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...
