During its prolonged clonal propagation, numerous deleterious mutations have accumulated in the potato genome,leading to severe inbreeding depression; however,the shaping of this mutation burden during polyploidization and improvement is largely unknown.Here, we sequenced 20 diploid landraces of the Stenotomum group, eight tetraploid landraces, and 20 tetraploid modern cultivars, to analyze variations in their deleterious mutations. We show that deleterious mutations accumulated rapidly during the polyploidization of tetraploid potatoes. This study provides a foundation for future potato improvement. 关键词：POTATOES STUDY
