Book Synopsis Plant Evolution under Domestication by : Gideon Ladizinsky
Download or read book Plant Evolution under Domestication written by Gideon Ladizinsky. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Plant Evolution and the Origin of Crop Species by : James F. Hancock
Download or read book Plant Evolution and the Origin of Crop Species written by James F. Hancock. This book was released on 2012. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Crop Evolution, Adaptation and Yield by : L. T. Evans
Download or read book Crop Evolution, Adaptation and Yield written by L. T. Evans. This book was released on 1996-05-02. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Grain Legumes by : Antonio M. De Ron
Download or read book Grain Legumes written by Antonio M. De Ron. This book was released on 2015-08-27. Available in PDF, EPUB and Kindle. Book excerpt: 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.
