Genetic map of cultivated cardoon ‘Altilis 41’. Marker names are shown to the right of each LG, with map distances (in cM) to the left. LGs containing <4 loci are labelled as ‘minor groups’. Loci showing significant levels of segregation distortion are identified by asterisks (0.1 > *P ≥ 0.05; 0.05 > **P ≥ 0.01). Segments shaded in red indicate where a pair of LGs has merged as a result of reducing the stringency to LOD 5.
