Plant evolution and the origin of crop species

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.
