Fig. 6From: Association mapping reveals a reciprocal virulence/avirulence locus within diverse US Pyrenophora teres f. maculata isolatesJitter genotype by phenotype plot for alleles A and B of the marker 3_630965 on barley line (A) MXB468 and (B) CI9819 using the 1–5 Ptm phenotyping scale [37] identified as the potential reciprocal virulence locus. Phenotypic scores are color coded based on isolate origin and standard error is displayed in blue for allele A and red for allele BBack to article page
