Global differences in production traits for 20 European local pig populations. Breeds are distributed according to breed scores for phenotypic traits and colored according to genetic similarity. Lower values for breed score growth represent lower average daily gain from weaning to 60 kg of live weight, while higher values represent higher average daily gain in the same growth period. Low values for breed score reproduction represent low reproductive performance, while high values represent breeds with higher reproductive performance. Low values for breed score stature represent lighter and smaller breeds, while high values represent heavier and larger breeds. Low values for the breed score fat represent leaner breeds, while high values represent fatter breeds. Breeds in green are genetically Landrace-like breeds, in purple Large White-like breeds, in blue Iberian-like breeds, in red Duroc-like breeds, and in light blue the Gascon and Basque breeds
