Solanum demissum Lindl. is one of the most valued and used species for potato (Solanum tuberosum L.) breeding due to its richness in genes for resistance to various biotic and abiotic factors. Over the years, it has been a plant of interest, mainly for its resistance to potato late blight (caused by Phytophthora infestans [Mont.] de Bary.), which has led to crosses between S. demissum and S. tuberosum to obtain resistant cultivars. It has also been used for identifying physiological races of P. infestans and, recently, it has been associated with glycoalkaloids and antioxidant compounds, whose potential uses are of interest to various industries. Since there is great potential in the species S. demissum, not only as a source of resistance genes but also as a source of important bioactive compounds, this review summarizes the research conducted on the use of Solanum demissum in the breeding of cultivated potato, as well as its potential uses in other areas. In addition, areas of opportunity and limitations for breeding for resistance to late blight are highlighted to serve as a starting point for the development of new research or lines.
