Key Concepts

Artificial Selection

Artificial selection is the process by which humans intentionally choose which traits should be passed on to future generations. In the context of food crops, it involves selecting plants that display favorable traits such as increased yield, improved taste, and enhanced resistance to pests, and then breeding these plants to reinforce these attributes over successive generations.

Crop Breeding

Crop breeding is the systematic practice of crossing plants to combine desirable traits and produce improved varieties. It relies heavily on artificial selection to identify and propagate individuals with superior qualities, thereby enhancing productivity, nutritional value, and adaptability to different growing environments.

Domestication

Domestication is the long-term process of adapting wild species for human use through sustained artificial selection. In food crops, domestication has transformed wild plants into cultivated varieties that are more amenable to agricultural practices, featuring traits like reduced bitterness, larger edible parts, and increased consistency in performance.
