While genetic diversity in potato cultivars is low, tremendous variation exists in wild relatives. Many of these relatives contain valuable genes for disease resistance, tuber quality, storability, and stress tolerance. Some are more easily crossable with the cultivated potato than others. In addition, when hybridized with the cultivated potato, variation exists among wild species in the ability to produce desirable tubers, adapted plants, and fertile offspring. This article summarizes challenges associated with the use of wild potato relatives in breeding and discusses their potential for cultivar improvement.
