Before revision:  Given that most tetraploid potato linkage maps have been generated either from diploid populations (Felcher et al., 2012) or from a subset of marker types (e.g. both parents were heterozygous) (Grandke et al., 2017), developing a map construction method based on discrete graphical models opens the opportunities to construct high-quality linkage maps for any biparental diploid and polyploid species containing all different marker types.
