This book is probably the only current volume to combine discussion of plant evolution with that of crop origins. The first edition was published in 1992 by Prentice-Hall, and has now been fully revised to reflect recent advances. Key features include: a description of the process of evolution in native and cultivated populations of plants; a review of when and where major crops were domesticated; discussion of the subsequent development of crops over time; and greater integration of the information on evolution and crop origins compared to the first edition. The book is aimed at advanced students and postgraduates.
