First published in 1949, this remarkable book is the culmination of a life-long study of every aspect of the potato. Dr Salaman is concerned first with the history of the potato as a member of the botanical genus Solanum, its adaptation by man as a cultivated plant, and the record of its spread throughout the world; secondly he considers the influence the potato has exerted upon the social structure and economy of different peoples at different times. The archaeological and anthropological evidence for the early significance of the potato among the peoples of Latin America is discussed in...

One of the world centers of crop evolution and origin, Ethiopia has long been recognized as an important area of diversity for several major and various minor crops. Based on an international conference held in Addis Ababa, this book describes how plant genetic diversity in Ethiopia is of vital importance in breeding new varieties of crops with desirable characteristics, such as increased resistance to pests and diseases and greater adaptation to heat and drought. The three main sections in the book consider the Ethiopian center of diversity, germ plasm or genetic material collection and...

This 1975 book deals with one of the world's fastest disappearing natural resources - the invaluable reservoir of genetic variability in our cultivated plants which have evolved since our forebears began to domesticate them some 10,000 years ago. The preservation of these 'genetic resources', as they have come to be called, is vital to mankind. Without them the geneticists and plant breeders cannot breed the new varieties needed to feed the world's population by providing more disease-resistant strains of our food plants. This volume explores topics such as how to collect and preserve this...
