Fig. 2 – Logarithm of odd (LOD) contours identified by composite interval mapping of powdery mildew APR QTL on
chromosomes 2BS, 3B and 5AL in the Pingyuan 50/Mingxian 169 DH population. A2010: maximum disease severities (MDS),
Anyang 2010; B2010 and B2011, maximum disease severities, Beijing 2010 and 2011, respectively; average: mean MDS across
three environments; AUDPC: averaged area under the disease progress curve in Beijing for more than two years. The LOD
threshold for significance is 2.0.
