The domestication of plants is one of the first and most crucial steps in the development of a full-fledged, reliable agricultural economy.To successfully feed a society using plants, the first humans had to continually work to improve their yield in quality and quantity. trough domestication and evolution contributes very important role in producing global food and crop plant improvement. Diversification may accompany or follow domestication, and results in variants within the crop adapted to different uses by humans or different agronomic conditions. First, I propose a method to systematically introgress diversity from crop wild relatives into crop breeding programs. Debates concerning the evolution and domestication of clonal crops are introduced with reference to Actinidia, Colocasia, Houttouynia, Manihot, Nelumbo, Saccharum, Solanum and other taxa.
