Technical Abstract: Wild and cultivated relatives of potato feature prominently in breeding programs. In this short article, I describe five exotic clones that have promising traits for the future of the US potato industry. They include M6, an inbred line of S. chacoense that provides a source of genes for self-compatibility, Verticillium wilt resistance, and soft rot resistance; US-W4 a potato dihaploid that is self-compatible, male fertile, and produces high-yielding offspring when crossed to diploid wild potatoes; XD3 a hybrid between US-W4 and a S. chacoense clone that is homozygous for a dominant gene for resistance to Potato Virus Y; M18 an inbred line derived from M6; and C287, an interspecific hybrid with resistance to Verticillium wilt and silver scurf.
