Germplasm Preservation

Preserving plant genetic resources is achieved through gene banks and the conservation of natural habitats.

Importance of Crop Plant Origins

Knowing their origins helps us find wild relatives and new genes for crop improvement.

Vavilovian Centres of Diversity

N.I. Vavilov proposed the idea that certain regions of the world are centers of origin for cultivated plants.
