简介

This book is a volume of series on“Crops and Their Wild Relatives”.It comprises two parts：Overview and Elaboration.The Overview part presents the information on categories and botanical，cytological and agronomic classification，and theories of origin and evolution of crops .The Elaboration part includes14chapters.Chapter1narrates categories，diversity and significance of food crops and their general status on production in the world and China.From Chapter2to Chapter14，it discuss separately the general status on production，the major characteristics on botany and biology，the origin，evolution，dissemination and classification，as well as cultivar evolution and propagation technologies of rice，wheat，barley，oats，maize，foxtail millet，broomcorn millet，sorghum，food legumes，sweet potato，potato，cassava and buckwheat.In each chapter，it also introduces crops relatives and their characteristics and relations with crops，and their utilization in crop breeding and production.This book is characterized by its distinctness，scienceness，theoreticalness and practicability with particular emphasis on the genetic diversity and its use values in crops and their wild relatives.It provides rich information and scientific basis for variety improvement and researches on taxonomy，origin and evolution of crops.This book will be useful reference for scientists working on crop genetic resources，genetics and breeding and biological diversity，and teachers and students in relevant universities and colleagues.。
