Summary:
The genetic variability that developed in plants during their evolution is the basis 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, 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.
