The potato has the potential to raise smallholder income and improve food security in Eastern Africa. While improving the quality of seed potatoes can contribute to increasing its productivity, most farmers largely rely on the seed potatoes they save themselves. Seed potato system interventions need to address the quality of specially multiplied and farm-saved seed potatoes simultaneously. This book shows that positive selectionthe selection of healthy looking mother plants for the production of seed potatoes by aware potato farmerscan contribute to improving seed potato quality and the quality of the subsequent harvest.

Sweetpotato and potato are expanding faster than any other food crops in sub-Saharan Africa. There is growing investment in research to address bottlenecks in value chains concerning these two crops, and growing interest from the private sector in investing in them. This book addresses five major themes on sweetpotato and potato: policies for germplasm exchange, food security and trade in Africa; seed systems; breeding and disease management; post-harvest management, processing technologies and marketing systems; nutritional value and changing behaviours.

This book describes the potential impact of the innovative hybrid breeding technology in potato. Conventional potato production is based on cumbersome breeding and multiplying of seed tubers. Seed tubers degenerate during the many generations of slow multiplication. Their bulkiness makes them difficult to store and transport. These issues are solved by hybrid true potato seed. Hybrid potato can help respond to the challenges of poverty, food security and climate change, especially in remote and harsh environments. Hybrid breeding will increase the turnover of cultivars in such environments once new seed systems based on hybrid true potato seed are established and regulated. With faster breeding and multiplication systems, clean seed can be produced of hybrid cultivars that respond to rapidly changing agronomic and socio-economic conditions. Public-private partnerships are crucial to facilitate the development and dissemination of hybrid cultivars that are adapted to the specific conditions and needs of the diverse types of potato growers in different environments and markets. These partnerships depend on knowledge and technologies emerging from international agro-industrial innovation systems. But next to this dominant innovation route, alternative systems are feasible with more emphasis on food sovereignty in farming systems that are less corporate and technology-driven, and more diversity-oriented.

This open access book describes recent innovations in food systems based on root, tuber and banana crops in developing countries. These innovations respond to many of the challenges facing these vital crops, linked to their vegetative seed and bulky and perishable produce. The innovations create value, food, jobs and new sources of income while improving the wellbeing and quality of life of their users. Women are often key players in the production, processing and marketing of roots, tubers and bananas, so successful innovation needs to consider gender. These crops and their value chains have long been neglected by research and development, hence this book contributes to filling in the gap. The book features many outcomes of the CGIAR Research Program in Roots, Tubers and Banana (RTB), which operated from 2012-21, encompassing many tropical countries, academic and industry partners, multiple crops, and major initiatives. It describes the successful innovation model developed by RTB that brings together diverse partners and organizations, to create value for the end users and to generate positive economic and social outcomes. RTB has accelerated the scaling of innovations to reach many end users cost effectively. Though most of the book's examples and insights are from Africa, they can be applied worldwide. The book will be useful for decision makers designing policies to scale up agricultural solutions, for researchers and extension specialists seeking practical ideas, and for scholars of innovation.

This book provides basic knowledge on how to produce, multiply and use propagation material in seed potato production and supply systems world wide. Healthy, vigorous seed tubers are essential in potato production. Producing them used to be expensive and difficult. Multiplication rates in the field are low, seed-borne diseases are numerous and seed tubers lose quality during storage between growing seasons. Recently, novel methods of multiplication have revolutionised the seed potato industry. This has resulted in a diversity of seed production systems adjusted to the local potential and needs. This book summarises the current knowledge and assesses the efficient use of modern technology in different stages of seed production. It describes in detail what seed quality means, how (pre-)basic seed can be produced, how this can be multiplied, and how seed health is maintained. It also describes diverse examples of seed supply systems in different regions of the world. The book is aimed at agronomists, farm advisors, seed producers, breeders, and at those involved in seed policies, seed programme development and seed trade. Also recommended for (international) students in agronomy, horticulture and plant breeding.

This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.

The stories presented in this report illustrate how improved collaboration among RTB centers is making a real difference. This includes harnessing the potential of genomics to accelerate the development of improved RTB varieties, facilitating collaborative responses to critical crop diseases and improving postharvest options. During its second year, the CGIAR Research Program on Roots, Tubers and Bananas (RTB) expanded its geographic reach and its network of partners while launching a series of collaborative initiatives aimed at resolving the most serious constraints faced by smallholder farmers growing RTB crops. While this work was initiated within a framework of seven disciplinary themes, RTB started a process to transition from an output-focused research agenda to one based on outcomes and impacts.

This publication is based on the proceedings of the Workshop "Strengthening Potato Value Chains in developing countries" held in November 2008. The presentations summarized in this publication are mostly based on experiences made in CFC (Common Fund for Commodities) potato sector development projects. In line with the policy to disseminate the information generated by CFC financed projects as widely as possible, it is our expectation that this publication will be instrumental to make impressive results and experiences of CFC pilot projects in the potato sector available to a wider audience. This document will be most useful and relevant to extension workers, researchers, policy makers and others involved in the development of the potato sector.

This book describes the historical importance of potato (Solanum tuberosum L.),potato genetic resources and stocks (including S. tuberosum group Phureja DM1-3 516 R44, a unique doubled monoploid homozygous line) used for potato genome sequencing. It also discusses strategies and tools for high-throughput sequencing, sequence assembly, annotation, analysis, repetitive sequences and genotyping-by-sequencing approaches. Potato (Solanum tuberosum L.; 2n = 4x = 48) is the fourth most important food crop of the world after rice, wheat and maize and holds great potential to ensure both food and nutritional security. It is an autotetraploid crop with complex genetics, acute inbreeding depression and a highly heterozygous nature. Further, the book examines the recent discovery of whole genome sequencing of a few wild potato species genomes, genomics in management and genetic enhancement of Solanum species, new strategies towards durable potato late blight resistance, structural analysis of resistance genes, genomics resources for abiotic stress management, as well as somatic cell genetics and modern approaches in true-potato-seed technology. The complete genome sequence provides a better understanding of potato biology, underpinning evolutionary process, genetics, breeding and molecular efforts to improve various important traits involved in potato growth and development.

African agriculture is currently at a crossroads, at which persistent food shortages are compounded by threats from climate change. But, as this book argues, Africa can feed itself in a generation and can help contribute to global food security. To achieve this Africa has to define agriculture as a force in economic growth by advancing scientific and technological research, investing in infrastructure, fostering higher technical training, and creating regional markets.
