Cultigen facts for kids
A cultigen is a special kind of plant that has been changed so much by humans that it can no longer grow on its own in the wild. These plants have been grown and selected by people for thousands of years. Because of this long history, their original wild forms are often unknown.
Think of plants like the sweet banana or the corn (maize) we eat. They are cultigens. They wouldn't survive without people planting them, caring for them, and harvesting them.

What Makes a Plant a Cultigen?
A plant becomes a cultigen through a process called domestication. This means humans have carefully chosen and grown plants with certain traits over many generations. For example, early farmers might have picked corn plants that had bigger kernels or bananas that were sweeter. Over time, these changes became so big that the plant became completely dependent on humans.
- No Wild Counterpart: The most important thing about a cultigen is that it doesn't have a wild version growing naturally anywhere.
- Human Selection: Its survival and spread depend entirely on people planting and caring for it.
- Ancient History: Many cultigens were developed thousands of years ago. This was so long ago that we often don't know exactly which wild plant they came from.
How Cultigens Help Us
Cultigens are super important for human life. Most of the food we eat comes from cultigens. Without them, it would be very hard to feed the world's population.
- Food: Many of our main food crops, like wheat, rice, potatoes, and most fruits and vegetables, are cultigens.
- Other Uses: Some cultigens are grown for other purposes, like cotton for clothes or certain flowers for their beauty.
Who Coined the Term?
The word "cultigen" was first used in 1918 by an American botanist named Liberty Hyde Bailey. He was a very important person in the study of plants and farming. He wanted a clear way to talk about plants that were created or changed by human activity, rather than those found naturally in the wild.
Examples of Cultigens
Many plants you see every day are cultigens. Here are a few common ones:
- Corn (Maize): Modern corn looks very different from its wild ancestor, teosinte. It has much larger kernels and cannot spread its seeds without human help.
- Banana: The sweet, seedless bananas we eat are cultigens. Wild bananas are full of hard seeds.
- Wheat: This grain, used for bread and pasta, has been bred over thousands of years to produce high yields.
- Rice: A staple food for billions, rice has been cultivated for a very long time and relies on human farming.
- Potatoes: These underground tubers have been selected for size and taste.
