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.

Aimed at the professional and postgraduate reader, this text describes the evolution and adaptation of grain. A pragmatic approach has been taken wherein adaptation has been traced for crop traits preferred by consumer demand and agro-ecological requirements in the production areas.

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 is divided into two parts. Part 1 deals with the evolutionary processes, describing the chromosome structure, genetic variation, multifactorial genome, polyploidy, gene duplication and speciation. Part 2 deals with the origins of agriculture and the dynamics of plant domestication, covering some cereal grains, protein plants, starchy staple and sugar crops, as well as fruit, vegetable, fibre and oil crops. A chapter on ex situ and in situ conservation of germplasm resources is included.

The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.
