Return to Resistance

Return to Resistance PDF Author: Raoul A. Robinson
Publisher: IDRC
ISBN: 9780889367746
Category : Agricultural pests
Languages : en
Pages : 502

Book Description
In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.

The Potato Crop

The Potato Crop PDF Author: Hugo Campos
Publisher: Springer Nature
ISBN: 3030286835
Category : Science
Languages : en
Pages : 524

Book Description
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.

Climate-Smart Food

Climate-Smart Food PDF Author: Dave Reay
Publisher: Springer
ISBN: 3030182061
Category : Nature
Languages : en
Pages : 200

Book Description
This open access book asks just how climate-smart our food really is. It follows an average day's worth of food and drink to see where it comes from, how far it travels, and the carbon price we all pay for it. From our breakfast tea and toast, through breaktime chocolate bar, to take-away supper, Dave Reay explores the weather extremes the world’s farmers are already dealing with, and what new threats climate change will bring. Readers will encounter heat waves and hurricanes, wildfires and deadly toxins, as well as some truly climate-smart solutions. In every case there are responses that could cut emissions while boosting resilience and livelihoods. Ultimately we are all in this together, our decisions on what food we buy and how we consume it send life-changing ripples right through the global web that is our food supply. As we face a future of 10 billion mouths to feed in a rapidly changing climate, it’s time to get to know our farmers and herders, our vintners and fisherfolk, a whole lot better.

Taxonomy of Wild Potatoes in Northern South America (Solanum Section Petota)

Taxonomy of Wild Potatoes in Northern South America (Solanum Section Petota) PDF Author: David M. Spooner
Publisher:
ISBN: 9781943751082
Category : Solanum
Languages : en
Pages : 305

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.

Innovation in Seed Potato Systems in Eastern Africa

Innovation in Seed Potato Systems in Eastern Africa PDF Author: Peter Gildemacher
Publisher: Kit Pub
ISBN: 9789460224072
Category : Potatoes
Languages : en
Pages : 0

Book Description
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.
