The genetic variability that developed in plants during their evolution is the basic of their domestication and breeding into the crops grown today for food, fuel and other industrial uses. This third edition of Plant Evolution and the Origin of Crop Species brings the subject up-to-date, with more emphasis on crop origins. Beginning with a description of the processes of evolution in native and cultivated plants, the book reviews the origins of crop domestication and their subsequent development over time. All major crop species are discussed, including cereals, protein plants, starch crops, fruits and vegetables, from their origins to conservation of their genetic resources for future development.

In this major 1993 work, Lloyd Evans provides an integrated view of the domestication, adaptation and improvement of crop plants, bringing together genetic diversity, plant breeding, physiology and aspects of agronomy. Considerations of yield and maximum yield provide continuity throughout the book. Food, feed, fibre, fuel and pharmaceutical crops are all discussed. Cereals, grain legumes and root crops, both temperate and tropical, provide many of the examples, but pasture plants, oilseeds, leafy crops, fruit trees and others are also considered. After the introductory chapter, the increasing significance of crop yields to the world's food supply is highlighted. The next three chapters consider changes to crop plants over the last ten thousand years, including domestication, adaptation and improvement. Aimed at research workers and advanced students in crop physiology and ecology, agronomy and plant breeding, this book also reaches conclusions of relevance to those concerned with developmental policy, agricultural research and management, environmental quality, resource depletion and human history.

This book emerged from a series of lectures on crop evolution at the Faculty of Agriculture of The Hebrew University of Jerusalem. While many textbooks are available on general evolution, only a few deal with evolution under domestication. This book is a modest attempt to bridge this gap. It was written for advanced undergraduate and graduate students in the fields of crop evolution, ethnobotany, plant breeding and related subjects. Evolution under domestication is unique in the general field of plant evolution for three main reasons: (a) it is recent, having started not much more than 10 000 years ago with the emergence of agri culture; (b) the original plant material, i. e. the wild progenitors of many important crop plants, still grow in their natural habitats; (c) man played in this process. These factors enable a more reliable a major role assessment of the impact of different evolutionary forces such as hybridization, migration, selection and drift under new circumstances. Interestingly, a great part of evolution under domestication has been unconscious and a result of agricultural practices which have created a new selection criteria, mostly against characters favored by natural selec tion. Introducing crop plants to new territories exposed them to different ecological conditions enhancing selection for new characters. Diversity in characters associated with crop plants evolution is virtually absent in theit wild progenitors and most of it has evolved under domestication.

This book deals with the agronomy of the eight major grain, fiber and oilseed row crops produced in the United States: Corn, Wheat, Grain Sorghum, Barley, Rice, Cotton, Soybeans, and Peanuts. For each crop, Dr. Smith presents a structured discussion of: the types of cultivars, the history of the crop, its uses and processing, a detailed discussion of how to plant and grow the crop, the pests and problems involved, and the harvesting, grading and marketing practices.

This book is devoted to grain legumes and include eight chapters devoted to the breeding of specific grain legume crops and five general chapters dealing with important topics which are common to most of the species in focus. Soybean is not included in the book as it is commonly considered an oil crop more than a grain legume and is included in the Oil Crops Volume of the Handbook of Plant Breeding.Legume species belong to the Fabaceae family and are characterized by their fruit, usually called pod. Several species of this family were domesticated by humans, such as soybean, common bean, faba bean, pea, chickpea, lentil, peanut, or cowpea. Some of these species are of great relevance as human and animal food. Food legumes are consumed either by their immature pod or their dry seeds, which have a high protein content. Globally, grain legumes are the most relevant source of plant protein, especially in many countries of Africa and Latin America, but there are some constraints in their production, such as a poor adaptation, pest and diseases and unstable yield. Current research trends in Legumes are focused on new methodologies involving genetic and omic studies, as well as new approaches to the genetic improvement of these species, including the relationships with their symbiotic rhizobia.

As human populations grow and resources are depleted, agriculture will need to use land, water, and other resources more efficiently and without sacrificing long-term sustainability. Darwinian Agriculture presents an entirely new approach to these challenges, one that draws on the principles of evolution and natural selection. R. Ford Denison shows how both biotechnology and traditional plant breeding can use Darwinian insights to identify promising routes for crop genetic improvement and avoid costly dead ends. Denison explains why plant traits that have been genetically optimized by individual selection--such as photosynthesis and drought tolerance--are bad candidates for genetic improvement. Traits like plant height and leaf angle, which determine the collective performance of plant communities, offer more room for improvement. Agriculturalists can also benefit from more sophisticated comparisons among natural communities and from the study of wild species in the landscapes where they evolved. Darwinian Agriculture reveals why it is sometimes better to slow or even reverse evolutionary trends when they are inconsistent with our present goals, and how we can glean new ideas from natural selection's marvelous innovations in wild species.

Darwin's Harvest addresses concerns that we are losing the diversity of crop plants that provide food for most of the world. With contributions from evolutionary biologists, geneticists, agronomists, molecular biologists, and anthropologists, this collection discusses how economic development, loss of heirloom varieties and wild ancestors, and modern agricultural techniques have endangered the genetic diversity needed to keep agricultural crops vital and capable of adaptation. Drawing on the most up-to-date data, the contributors review the utilization of molecular techniques to understand crop evolution. They explore current research on various crop plants of both temperate and tropical origin, including maize, sunflower, avocado, sugarcane, and wheat. The chapters in Darwin's Harvest also provide solid background for understanding many recent discoveries concerning the origins of crops and the influence of human migration and farming practices on the genetics of our modern foods.
