Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Potato is a crop grown on all inhabited continents of the globe. It is included in the top five crops of the world, used as staple food in several countries, and the number of people daily consuming the potato may surpass one billion. Despite the high quantities of seed potato produced worldwide, there are yield gaps due to challenges such as abiotic stresses, pests, climate change and poor production practices. A region-wide critical analysis of yield declining factors can help formulate management strategies that can improve potato yields. Bridging yield gaps in potato will ultimately ensure the role of this crop in securing current and future food security. Potato Production Worldwide presents information on this global crop from its history, morphology, and taxonomy to the growth and development of the potato crop, including the latest strategies in addressing today's biotic and abiotic challenges. This book identifies the reasons for yield gaps in various potato production regions of the world, as well as presenting the best production practices, pest management strategies and approaches to deal with climate change from the perspective of potato production. Chapters provide important insights into potato production cultures and approaches in the major potato production countries. Potato Production Worldwide will be a valuable resource for researchers, scientists and students seeking a comprehensive view of successful potato production. - Provides comprehensive information on the origin, history, taxonomy, morphology, ecophysiology, growth and development of the potato - Addresses production practices, including irrigation, nutrient management, harvesting and post-harvest techniques - Explores the impact of Abiotic stresses (drought, chilling, salinity etc.) and their management

Book Description
Experts discuss the challenges faced in agrobiodiversity and conservation, integrating disciplines that range from plant and biological sciences to economics and political science. Wide-ranging environmental phenomena—including climate change, extreme weather events, and soil and water availability—combine with such socioeconomic factors as food policies, dietary preferences, and market forces to affect agriculture and food production systems on local, national, and global scales. The increasing simplification of food systems, the continuing decline of plant species, and the ongoing spread of pests and disease threaten biodiversity in agriculture as well as the sustainability of food resources. Complicating the situation further, the multiple systems involved—cultural, economic, environmental, institutional, and technological—are driven by human decision making, which is inevitably informed by diverse knowledge systems. The interactions and linkages that emerge necessitate an integrated assessment if we are to make progress toward sustainable agriculture and food systems. This volume in the Strüngmann Forum Reports series offers insights into the challenges faced in agrobiodiversity and sustainability and proposes an integrative framework to guide future research, scholarship, policy, and practice. The contributors offer perspectives from a range of disciplines, including plant and biological sciences, food systems and nutrition, ecology, economics, plant and animal breeding, anthropology, political science, geography, law, and sociology. Topics covered include evolutionary ecology, food and human health, the governance of agrobiodiversity, and the interactions between agrobiodiversity and climate and demographic change.

Book Description
The potato is the world’s most important non-cereal food, with a global production of 370 million tonnes. The cultivated potato, Solanum tuberosum L. (AABB, 2n = 4x = 48, genome size 844 Mb), belongs to Solanum section Petota and was domesticated in the South American Andes about 8.000 to 10.000 years ago. The Petota section is characterized by a broad genetic diversity involving introgressions, interspecific hybridization events, auto‐ and allopolyploidy, and a high degree of morphological similarities. Overall, 7 cultivated and 228 wild species (Hawkes, 1990) or 4 cultivated and 107 wild species (Spooner et al., 2014) were described and are conserved through 82,000 accessions in 89 institutions. Depending on the genetic material, clonal plants are preserved in field genebanks and/or in vitro slow-growth storage and/or cryopreservation or as seeds in cold storage facilities. However, challenges for efficient identification of collection gaps, conservation, and usage of potato genetic resources in potato breeding programs, are the differences in taxonomic classification, the limited information, and advances in characterization, evaluation, sequencing, and conservation approaches. The aim of this research topic is to highlight the latest developments and strategies in the conservation and use of potato genetic resources. It addresses different scientific fields, i.e. plant physiology, genetics, functional genomics, phenomics, taxonomy, computer modeling, and database management.
