Concept

Centers of Origin

Also Known As Vavilov centers
Genetic Resources and Crop Diversity

The geographic regions where crops were first domesticated and where their wild relatives and greatest genetic diversity still live. Nikolai Vavilov proposed the idea in 1924 and kept refining the map all his life, counting three centers at first, then five, six, seven and eight as the evidence grew. The concept tells breeders where to look for the traits a crop has lost and tells conservation where losing a landscape means losing a crop's deep reserves.
