Crop Evolution and Domestication Syndromes

Résumé

Crops evolved through evolution and domestication process and different crops either have different or similar origin. Evolution and domestication process is progressing process starting with wild species, then formation of cultivated one and selection of improved strain of the species by growers and researchers. These processes may happen due to mutation, immigration, artificial selection, natural selection, speciation and cross. Evolution and domestication process then results difference among domesticated as well as evolved crops from their wild progenitors and this coined as syndromes. The syndromes discussed in this paper includes plant height and growth habit, flowering time inflorescence size and morphology, fruit size and morphology, organ color and toxic substance, seed size and dispersal and seed dormancy. As future direction, studying the wild species more and more and maintaining them enables to develop crops that are resist to biotic or abiotic stresses and obtaining yielding crops varieties.
