Fig. 4From: Population structure of Venturia inaequalis, a causal agent of apple scab, in response to heterogeneous apple tree cultivationBarplot showing the average mean Q values for 20Â V. inaequalis populations, representing the admixture between two main inferred clusters: one comprising Rvi6 and the other Rvi6-avirulent populations. Each bar contains the Q values calculated by a) STRUCTUREÂ 2.3.4 or b) TESS 2.3.1 softwareBack to article page
