Genetic map of globe artichoke ‘Romanesco C3’. Marker names are shown to the right of each LG, with map distances (in cM) to the left. One LG containing <4 loci is labelled as ‘minor group’. 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.
