Crop Evolution and Genetic Resources covers all aspects of plant genetic resources research in taxonomical, morphological, physiological, biochemical, genetic, cytological or ethno botanical research on genetic resources and includes contributions to gene bank management: collecting, maintenance, evaluation, storage and documentation. Diversity of the plant genetic resources plays a key role in agricultural development. Systematic identification, characterization, and evaluation of this diversity are a pre-requisite for its scientific management. The advent of the Convention on Biological Diversity led to a paradigm shift from genetic resources being considered as common heritage of mankind to sovereign rights of nations. This book will be useful for undergraduate and post-graduate students, teachers and researchers in the field of practical plant breeding, cytogenetic and biotechnology.
