DOIAbstract
Wild and cultivated potatoes form a polyploid series with 2n = 2x to 2n = 6x (x = 12). In nature, they are separated by external and/or internal hybridization barriers that, when incomplete, provide opportunities for gene flow and introgression. Isolation distances estimated in one environment are not necessary extrapolable. As a starting point for pollen-mediated gene flow risk assessment in potatoes, an experiment was set up in the field in one of the major potato growing area in Argentina, with two pollen-pistil compatible tetraploid commercial cultivars with differential molecular marker patterns. The field design consisted of a 10 × 10 m central square with the pollen donor, surrounded by circles with a male sterile pollen recipient, s...
