Table 4 QTL analysis performed for Stagonospora nodorum blotch resistance by interval mapping of F2 progeny derived from a cross of Arina ( by an F2 progeny from a cross between Alsen and Ocoroni86 that was homozygous for the molecular markers linked to the Fhb1 (Alsen) and Sr2 (Ocoroni86) resistance genes

  1. aThe R2 (%) is the amount of phenotypic variation associated with the QTL
  2. bAdditive and dominance genetic effects for an allelic substitution were estimated using QTL Cartographer 2.5. Negative numbers indicate that the effect came from Arina
