Solanum section Petota., which includes the cultivated potato (S. tuberosum) and its wild relatives, is distributed from the southwestern United States to central Argentina, Uruguay, and adjacent Chile. This taxonomic treatment includes all wild species of section Petota from northern South America, which includes Venezuela, Colombia, Ecuador, and Peru. It is the last of five taxonomic treatments of a monophyletic potato + tomato + section Etuberosum clade, including treatments of 1) wild potatoes from North and Central America, 2) wild potatoes from southern South America, and the close outgroup section Etuberosum, 3) cultivated potatoes, and 4) wild tomatoes. Wild species of section Petota include diploids (2n = 24), triploids (2n = 36), tetraploids (2n = 48), and hexaploids (2n = 72), with all of these levels represented in northern South America. We here recognize 60 species from section Petota in this region and partition them into five species groups, recognizing only about half of the species from northern South America relative to the most recent taxonomic treatments by J.G. Hawkes and C.M. Ochoa. We summarize recent morphological and molecular studies of species limits and their interrelationships, and provide a key to the species, descriptions, synonymies (including designations of lectotypes), illustrations, localities, disease resistances, and distribution maps for all species.

This atlas describes the ecogeographic distribution of wild potatoes. They occur solely in the Americas, from the southwestern United States to central Argentina and Chile. To help the nonspecialist to understand the past and future changes in their classification, we first discuss the habitats, morphology, and taxonomy of wild potatoes. This is followed by a discussion of problems of data and information quality associated with the locality databases that were used for the maps in this atlas. Distribution maps are provided for all species and series (a taxonomic level that groups related species). Finally, statistics on ecogeographic distribution of wild potatoes, and analytical maps of species richness and series richness are provided.

This book gathers the latest information on the organization of genomes in wild Solanum species and emphasizes how this information is yielding direct outcomes in the fields of molecular breeding, as well as a better understanding of both the patterns and processes of evolution. Cultivated Solanums, such as potato, tomato, and pepper, possess a high number of wild relatives that are of great importance for practical breeding and evolutionary studies. Their germplasm is often characterized by allelic diversity, as well as genes that are lacking in the cultivated species. Wild Solanums have not been fully exploited by breeders. This is mainly due to the lack of information regarding their genetics and genomics. However, the genome of important cultivated Solanaceae such as potato, tomato, eggplant, and pepper has already been sequenced. On the heels of these recent developments, wild Solanum genomes are now becoming available, opening an exciting new era for both basic research and varietal development in the Solanaceae.

This authoritative and scholarly 1990 treatise on the potatoes of Bolivia provides a definitive guide to the rich diversity and taxonomy of this important group of plants. The volume represents the culmination of a lifetime's study of these potatoes by Carlos Ochoa, and is published in collaboration with the International Potato Center in Lima, Peru. The text is abundantly illustrated throughout with clear line drawings, photographs and many specially commissioned watercolours, which identify the characteristic features of these plants and their natural habitats. The great variety of these wild potatoes within Bolivia provides botanists and plant breeders with a unique resource for the study of the cultivated varieties and the development of improved cultivars. This volume presents a thorough taxonomic treatment of all these varieties and incorporates valuable information about their distribution and habitat preferences which is illustrated through the use of maps and photographs.
